Last Friday I published "Battery Investing for Beginners" as an introductory piece for investors who don't know much about the energy storage sector but are interested in learning more because of the hugely successful initial public offering by A123 Systems (AONE). Since the article was well received and there seems to be a good deal of reader interest, I've decided to continue the theme with a series of articles where I'll try to build a contextual framework for the industry and show where various types of energy storage devices and their manufacturers fit into that framework. Since I don't want to spend too much time replowing old ground, I'll rely on hyperlinks to my earlier blogs and third party source documents.
I'm a lawyer, not a journalist. My undergraduate degree was in accounting with a solid base of hard science. I've spent the last 30 years working in securities law where most of my work involved small natural resource or technology development companies. I'm not an engineer or scientist, but my chosen field of practice requires me to understand the science well enough to explain it. My foundation in the energy storage sector dates to 2003 when I took on a client named Axion Power International (AXPW.OB) that was organized to develop a novel energy storage device that's half lead-acid battery and half supercapacitor.
I spent the next five years working as Axion's general counsel and served as a member of its board for four of those years. I stepped down from my position as Axion's board chairman in January 2007 and brought in successor legal counsel in early 2008. I still own a substantial long position in its stock. In short, I know the energy storage sector well and understand what the principal players are trying to accomplish, but I come from the lead-acid side of the business and because of my long history with high-tech innovation I'm not as excited by gee-whiz technology as many commenters. I like to think of myself as a cautious optimist who sees the opportunities but never overlooks the challenges.
Everybody understands the basic problem. We passed an inflection point for peak cheap oil in the late '90s and fuels that are expensive today can only become more costly in the future. We've also passed the inflection point for peak cheap electricity. When you factor in concerns over CO2 emissions as a possible cause of climate change, we have a real mess on our hands. The good news is that fundamental economics are finally kicking in and forcing us to attack the issue of energy waste while we search for new ways to generate electricity from non-traditional sources. Merrill Lynch strategist Steven Millunovich believes we are at the dawn a new industrial revolution, the age of cleantech. I believe he's right.
When I started writing this blog, I decided to limit its scope to "pure-play" energy storage device manufacturers that file regular reports with the SEC. The decision resulted in three noteworthy exclusions: Johnson Controls (JCI), which is the largest battery manufacturer in the world but only gets 15% of its revenue from battery sales; SAFT Groupe (SGPEF.PK), a profitable French battery manufacturer that does not file reports with the SEC; and BYD (BYDDY.PK), a Chinese manufacturer of cell phones and automobiles that gets 23% of its revenue from battery sales and does not file reports with the SEC. The decision also left me with a small but reasonably comparable short list of companies that only differ in the nature of their products and the development stage of their businesses. For investors who would rather track an index that includes JCI and BYD, I recommend the Energy Storage and Battery Technology Stocks Index (*BTTRY) published by Tickerspy.
There are two basic classes of energy storage devices: cool devices like lithium-ion batteries, supercapacitors and high-speed flywheels that promise extraordinary performance and are relatively expensive in terms of cost per unit of storage capacity; and cheap devices like lead-acid batteries, flow batteries and low-speed flywheels that offer lower levels of performance but are relatively inexpensive. My favorite source of cost data on energy storage technologies is a July 2008 Sandia National Laboratories report on its Solar Energy Grid Integration Systems – Energy Storage (SEGIS-ES) program. The following table separates the raw Sandia data into short duration power technologies, short duration energy technologies and long duration energy technologies; orders the technological contenders based on the average of current and 10-year projected cost data reported by Sandia; and identifies the American companies I follow that are focused on each storage technology.

There are also two basic classes of pure-play energy storage companies: emerging entrepreneurial companies that are developing new technologies; and established manufacturing companies that have solid customer bases and sustainable business models. A fifth and final class is a rapidly expanding group of Chinese battery manufacturers that have listed their shares in the U.S. but are not expected to be major players in the growth of America's domestic battery industry.
To allow for fundamental differences among their technologies and business models, I've segregated my universe of pure play energy storage companies into five classes that I'll briefly describe below and summarize in a series of tables that identify the individual companies and provide summary data on their share prices, market capitalizations and key financial ratios.
Cool Emerging -My cool emerging class consists of thinly-capitalized developers of relatively expensive energy storage technologies. Their annual operating losses are typically large in relation to their total assets and they'll be dependent on additional financing for an indeterminate period of time. Cool emerging companies are typically valued on the basis of the perceived potential of their technology and their expected time to market.
| Name | Symbol | Price | Mkt. Cap. | P/E | P/B | P/S |
| Ener1 Inc | HEV | $7.07 | $826.0 | 9.8 | 37.5 | |
| Valence Technology | VLNC | $1.81 | $229.7 | N/A | 11.6 | |
| Altair Nanotechnologies | ALTI | $1.17 | $123.5 | 2.7 | 33.8 | |
| Beacon Power | BCON | $0.73 | $88.1 | 4.2 | 213.7 |
Cool Sustainable -
My cool sustainable class consists of well-capitalized developers of relatively expensive energy storage technologies that have a substantial customer base. Their annual operating losses are typically smaller in relation to their total assets and their need for additional financing is generally less pressing. Cool sustainable companies are typically valued on the basis of their earnings potential and business development plans.
| Name | Symbol | Price | Mkt. Cap. | P/E | P/B | P/S |
| A123 Systems | AONE | $18.73 | $1,838.9 | 3.6 | 20.5 | |
| Maxwell Technologies | MXWL | $19.27 | $500.5 | 6.2 | 5.4 | |
| Ultralife Corporation | ULBI | $5.90 | $99.8 | 1.3 | 0.5 |
Cheap Emerging -
My cheap emerging class consists of thinly-capitalized developers of relatively cheap energy storage technologies. Their annual operating losses are typically large in relation to their total assets and they'll be dependent on additional financing for an indeterminate period of time. Like their cool counterparts, cheap emerging companies are typically valued on the basis of the perceived potential of their technology and their expected time to market.
| Name | Symbol | Price | Mkt. Cap. | P/E | P/B | P/S |
| Axion Power | AXPW.OB | $2.12 | $75.9 | 18.3 | 62.8 | |
| ZBB Energy | ZBB | $1.24 | $15.4 | 1.9 | 8.7 |
Cheap Sustainable -
My cheap sustainable class consists of well-capitalized manufacturers of relatively cheap energy storage technologies that have a substantial customer base. Like their cool counterparts, cheap sustainable companies are typically valued on the basis of their earnings potential and business development plans.
| Name | Symbol | Price | Mkt. Cap. | P/E | P/B | P/S |
| Enersys | ENS | $21.71 | $1,040.0 | 15.7 | 1.4 | 0.6 |
| Exide Technologies | XIDE | $8.01 | $604.9 | 2.0 | 0.2 | |
| C&D Technologies | CHP | $2.14 | $56.3 | 1.3 | 0.2 | |
| Active Power | ACPW | $0.88 | $58.2 | 3.1 | 1.3 |
Chinese Companies -
My last class consists of Chinese companies that have listed their shares in the U.S., but operate solely in Asia. They're generally profitable and may export products to the U.S., but they're not expected to be key players in America's drive to develop a thriving domestic battery manufacturing industry.
| Name | Symbol | Price | Mkt. Cap. | P/E | P/B | P/S |
| Advanced Battery Technologies | ABAT | $4.09 | $253.1 | 11.8 | 2.1 | 5.3 |
| China BAK Battery | CBAK | $4.19 | $241.7 | 1.5 | 1.1 | |
| China Ritar Power | CRTP | $5.47 | $105.3 | 20.0 | 2.8 | 1.0 |
| Hong Kong Highpower | HPJ | $3.34 | $45.3 | 23.2 | 2.5 | 0.7 |
My fundamental premise is that current conditions in the energy storage sector are a lot like they were in high-school.
There are four publicly held lithium-ion battery developers vying for supremacy in the high profile contest to become the technology superstar for PHEVs and EVs. They're competing against each other, a number of foreign companies and a host of privately held companies for a market that will be a long time coming. While they all trade at prices that would give value investors a nosebleed, the odds that a particular company will make it to the NFL draft are remote at best.
At the other end of the spectrum there are a small number of emerging and sustainable companies that are manufacturing and developing technologies for the more mundane energy storage needs of the average consumer who would be hard-pressed to buy a $22,000 Prius class hybrid, much less a $40,000 Volt class PHEV.
As the newly born excitement over the energy storage sector wanes and fundamental investment analysis gains supremacy, I expect the relative valuations of the cool technology companies to either remain flat or fall while the relative valuations of the cheap technology companies rise to more reasonable levels. On Thursday I'll put together an analysis of how that investment thesis has held up since last November and establish a new set of foundation metrics for future tracking comparisons. I continue to believe cheap will outperform cool for the foreseeable future. Only time will tell whether I'm right or wrong.

We've all grown up with the idea that shortage means we'll have to pay more. For a lot of these critical raw materials we're about to learn that the word shortage means not available at any price.
Jack Lifton is absolutely right when he argues that encouraging the domestic production of batteries without encouraging the domestic production of raw materials to make the batteries is a fool's errand that simply exchanges one form of dependence for another.
1) The Grant winners including A123 and JCI/Saft have promised to build factories in Michigan and in Florida respectively for U.S. based Lithium-ion battery cells.
2) While I applaud them for getting this money in order to bring jobs to the U.S. in a terrible economic situation, I also have to think that these "factories" will not be on-line until 2012 if all goes smoothly, and all the environmental issues can be resolved?
3) Given the points that Jack makes and the fact that new mining operations here, and in other parts of the world, cannot be ramped up to meet demand for at least 5 years (if we start today) the prospect of raw material shortages are going to impact these ventures in a way that nobody has really though through yet.
4) The Chinese are already making noises and submitting white papers to the government that indicate they will probably restrict the export of their rare earth metals which means any factories built here will be impacted in ways that are now unforseen.
My conclusion is that the best course for LiFeBATT moving forward is to keep the production of our battery cells off-shore, either in China or Taiwan, and to focus on engineering complete plug & play systems with a dual mode of execution of our business plan. We will continue to import both complete battery packs from our Taiwan assembly plant and also individual cells and components to assemble complete packs here in the U.S. @ our facility in Virginia. This will enable us to best service our customer base without venturing into manufacturing of cells domestically. The more I have been thinking about this the more I am almost glad we didn't get one of these government grants and have to build a manufacturing plant from scratch. I will watch A123 and JCI/SAFT with great interest to see how they accomplish this task and how much support they get from investors?
My gut feeling is that these new "factories" will not be able to compete in price or quality that we can get now from our Asian suppliers given that they have a big headstart and we can ramp up their QC and their cell making technolgy much quicker than these new ventures can build plants from ground zero.

For production at Ovonic Materials there were two 1000 lb capacity continuous operation vacuum induction furnaces, a powder metal production facility (very fine powder in the micron and submicron range), and a Raney nickel reactor for charging nickel-metal hydride alloy powders with hydrogen. The entire operation is in a building designed to safely process with hydrogen, and the powder metal production equipment is in a separated room capable of automated operation under inert atmosphere.
I have known Stan Ovshinsky for 61 years, and I never once knew him to stint on costs by buying second rate equipment.
I am going to guess that duplicating the facility would cost between 10 and 20 million dollars and the skill of the remaining workforce is priceless.
I believe that GWMG picked up the facility (in a leased building) for at most $2 million-it was a steal if it goes back into operation.

Thanks again for inciting this excellent forum for discussion on various battery (storage) solutions. Your many contributors bring a useful and diverse experiences to the discussion along with many good insights. Having used a number of various battery technologies over many years for small capacity but demanding applications, I appreciate the auto vehicle problems where real costs are a big part of the equation (unlike many research applications). A relevant question is how much will these developments (or lack thereof) affect our economy and future? The question of natural resources is very interesting, but perhaps less than critical because we have often overcome the difficulty of providing for external resource needs. The cold war mentality promoted the concept that we must become self sufficient in everything, but it isn't always necessary for successful production of a product in demand worldwide.
Now that A123 has launched their successful IPO they are trying to bury the lawsuit against them by U.T. and Phostech and I expect they will want to do this very soon. See Bloomberg link below:

Your incessant rants against the usage of batteries in PHEVs rather than in HEVs are unnecessary. The market should be able to deal with the allocation of battery production between PHEVs and HEVs because, at least in the US, the current economics of an unsubsidized PHEV purchase is terrible and that of an unsubsidized HEV purchase is marginal. As a side note, these rants are not in your self interest since you should be encouraging the demand for large format batteries, the area where Axion competes. Digression over, let’s put some numbers to HEV vs. ICV and PHEV vs. HEV economics for the US.
First let’s compare the economics of a 50-mpg HEV with a 30-mpg ICV. Assume 12,000 miles per year of driving, $3 per gallon gasoline and a $4,000 price premium for the HEV compared to the ICV. The HEV would consume 240 gallons per year, which is 160 gallons less than the 400 gallons annually consumed by the ICV, for an annual fuel saving of $480. Over a 10-year period (of stagnant gasoline and electricity prices), the savings total $4,800, for an ROI of 3.5% on $4,000 – an ROI well below loan interest rates. However, the ROI is fairly sensitive to the annual mileage that one assumes. For example, at 20,000 miles per year, the fuel savings are $800 annually and $8,000 over ten years for an ROI of 15.1 % on the $4,000 price premium. For less than 10,000 miles of annual driving for 10 years, the ROI is negative.
As mentioned, the current economics of a PHEV are terrible compared to an HEV. The energy savings arise because the 1 kWh of electrical energy required to move a PHEV 5 miles costs 5¢ (assumed off-peak charging rate) and the 1/10 of a gallon of gasoline required to move a HEV the same distance costs 30¢. Therefore, every kWh of battery charge used to propel the PHEV will save 25¢. However, the cost of 1 kWh of battery capacity is about $1,000, with promises of a much lower price, and it would provide about 2,500 charge-discharge cycles – enough for 250 commutes annually or 2,500 commutes over 10 years. Over this ten-year period, the net energy savings per kWh would be $62.50 annually and $625 for ten years, for an ROI on $1,000 of – 7.74 % (yes, minus 7.74 %). At a $500 per kWh battery cost, the ROI on the $500 would still be a less than sterling 4.3 %.
For Europe, the economics are more favorable. Assuming energy costs of 10¢ per kWh and $7 per gallon, and 9,000 miles of annual driving or 250 annual commutes, I get ROIs of 16.4 % for HEV vs. ICV and 8.1 % for PHEV vs. HEV. Throw in the diesel factor (10 % less fuel consumption), and these ROIs become 13.0 % and 5.3 %, respectively.
In summary, there is nothing in these numbers that suggest PHEVs should fly off the showroom floors in the US or Europe, unless heavily subsidized.
What I'm gathering is that more than a few commentators in your columns I've been reading since July '08 are writhing and screaming about how you ignore all the potentials of the future (I was one of them back then). Yet, it is apparent to me, other than the very kind Don Harmon, that no one is putting serious money behind their beefs. If they have, you have more than proven to this investor, that their money is languishing.
Our government, through it's recent generous awarding of billions to the battery sector underscores how important batteries are for national security reasons. But what goes into the batteries (REEs) is far more important. That China controls 97% of all the world's REEs scares the bejesus out of me.
For your pro-lithium readers I suggest they check (AMLM). Possibly, a within-the-USA answer to where lithium will come from. But that mine is still three years out from "possibly" producing lithium for batteries.
(That's the way I'm playing lithium, and (ALML) was one of the very few stocks up in yesterday's market evisceration; up another nickle today)
