As a lawyer, I’ve had the privilege of working with some of the finest scientific minds in the world. They all started with brilliant concepts and impressive laboratory results, but a substantial majority failed to create a viable business.

After countless clients that started well and ended up mired in a swamp, I’ve come to understand that technology is a two-edged sword. On the leading edge, developers of low cost technologies can build fortunes. On the bleeding edge, developers that can’t control their costs and manufacture competitive products often morph into the financial equivalent of a black hole. Sadly, I believe most current developers of advanced Li-ion batteries are on the bleeding edge of energy storage technology and are doomed to spend years, if not decades, hemorrhaging cash.

I frequently feel like Cassandra, the Greek princess who was given the gift of prophecy and then cursed so that no one would believe her. When I read reports about how an MIT researcher has developed a new material that will allow Li-ion batteries to recharge in seconds or how Japan’s national alternative energy development agency has targeted a 50% reduction in Li-ion battery costs over the next year, I don’t get excited over the mirage of progress.

Instead, I start asking buzz kill questions like “How much will these new materials add to the cost of a battery?” and “How can anybody reasonably target a 50% price reduction over the next year when the average has been 5% for the last 20 years?” The answers, of course, are “plenty” and “they can’t.” The stories are cheerleading and hype, not rigorous analysis; and we all know what happens when optimistic forecasts collide with immutable economic laws.

The fact is that everyone, including me, wants an easy, quick and painless solution to our growing energy dilemma. However wishes, hopes, dreams and desires can’t change the fact that until somebody overcomes the cost, performance, abuse tolerance and cycle-life issues that the DOE has analyzed in depth and I’ve discussed in earlier blogs, there will be no Li-ion solution for the average consumer’s energy storage needs. Progress is being made, but it’s an uphill battle where the goal is measured in miles and the progress is measured in feet.

Every time I mention the elephant in the living room, I’m inundated with comments suggesting that the data I’ve cited is old or unreliable. The contrary authority invariably says something like “Lyons said that most estimates put the near-future cost for battery manufacturing at $250-300 per kWh once economies of scale are ramped up” or points me to a Chinese website. The only response I can offer is balderdash! With annual revenues of several billion dollars, the Li-ion battery sector already has plenty of scale. What it lacks are meaningful potential economies.

Economies of scale are modest savings that can reduce per unit cost as a profitable business grows. They arise from factors like discounts on raw materials purchases, greater worker specialization, lower financing costs and reduced spending on ancillary items like research and development. For a more detailed discussion of the topic, see “What Are Economies of Scale?

An estimated 75% of the cost of a battery goes for raw materials. So unless you insist on believing in a commodity fairy that will slash raw materials costs despite rapidly escalating global demand, you can’t honestly believe that vaguely defined economies of scale will make insanely expensive products affordable. Even the happy talk articles like the most recent one from Japan merely serve to prove the point:

“NEDO also analyzed battery cost (not a cell but a battery pack) as of March 2009. It estimates that the cost is about ¥200,000/kWh (approx US$2,016/kWh) for both types of batteries.”

In January I published a comparative breakeven analysis for an EV-40 and an EV 100 using the $1,333 per kWh value for Li-ion batteries that I took from a July 2008 Sandia Laboratories report on its Solar Energy Grid Integration Systems – Energy Storage Program. That analysis showed that an EV-40 could not break even at gas prices of less than $3.70 and an EV-100 could not break even at gas prices of less than $9.20. Even if I use the latest happy-talk target out of Japan and give effect to the vainly anticipated battery price collapse, the breakeven points work out to $3.02 for an EV-40 and $7.54 for an EV-100. At those prices, there are only two classes of buyers, the emotionally committed and the mathematically challenged. This is not encouraging news in a recession.

When evaluating any company, the first thing I want to know is whether it can sell a product and earn a reasonable gross margin on the sale because without gross income net income is impossible. In general, high gross margins are wonderful things and low gross margins are very bad things.

The universe of publicly traded Li-ion battery manufacturers is small so there are not a large number of reliable data points. Nevertheless, I was able to do some digging through SEC filings and cobble together the following table that compares historical product sales, gross profit and gross margin data for five active Li-ion battery manufacturers (Click on the table for a PDF version).


From both a revenue growth and gross margin perspective, Advanced Battery (ABAT) has been an impressive performer and seems to be on the leading edge of Li-ion technologies. At the other end of the spectrum, Valence Technology (VLNC) and A123 Systems seem to be stuck on the bleeding edge. While Ener1 (HEV) and China BAK Battery (CBAK) have modest gross margins, their performance falls far short of leading edge; in fact, they’d be poor performers among the conventional battery manufacturers that I’ve identified in the following table.


Over the course of my career I’ve had substantial experience with both leading edge and bleeding edge companies. As a lawyer, I try to discourage potential clients from starting down a road that has a low chance of commercial success because life is short and dealing with disappointed investors is never pleasant. Once a project begins I carefully watch for signs that a client is tending away from the leading edge and toward the bleeding edge because an early failure is invariably easier to cope with than a client that lives on the bleeding edge for years. Factors I view as warning flags that a company is approaching the bleeding edge include:

Countertrend revenues

When companies like Ener1’s Korean subsidiary report revenue declines while their peers are reporting substantial revenue increases, I see yellow and orange flags.

Gross margins

High gross margins are usually a reliable indicator of a superior product and small gross margins can be tolerable in high volume industries, but negative margins are a red flag.

Debt financing

In the absence of a long and well-established earnings history, substantial debt is toxic and leading edge companies don’t have substantial liabilities to anyone.

Related party debt

A heavy reliance on insider financing is normal during the formative years, but when the insiders of public companies like Valence and Ener1 purchase secured debt instead of straight equity the risk to common stockholders skyrockets.

Idle factories

In the absence of a cogent explanation, idle factories are a red flag that the owner cannot manufacture and sell a commercially viable product. There are always opportunities for viable products and a manufacturer like Ener1 that can’t harvest the low hanging fruit will rarely succeed with more sophisticated customers.

Operating expenses

Leading edge companies like Advanced Battery aggressively control operating expenses at all levels, which permits them to take over 70% of their gross margin to the bottom line. Profligate spenders like Ener1, Valence and A123 are far closer to the bleeding edge.

Nosebleed valuations

When a market leader like Advanced Battery trades at 6.8 times earnings and has a market capitalization of $110 million, no reasonable investor can justify market capitalizations of $193 million or $483 million, respectively, for companies like Valence and Ener1 that have never even come close to reporting a profit.

PR perspective

Leading edge companies talk about events while bleeding edge companies publicize goals. What will happen if the DOE reviews A123’s $1.8 billion loan request or Ener1’s $480 million loan request and decides the requests don’t meet regulatory requirements?

Veiled hubris

New entrants in a technological field are almost never better at manufacturing and marketing than their entrenched competitors who offer comparable products. Li-titanate batteries from Ener1 may compete with Toshiba’s SCiB line, but they are unlikely to be demonstrably better or cheaper. Likewise Li-phosphate batteries from Valence and A123 may compete with products from BYD, but assuming competitive superiority without demonstrable proof is the pinnacle of veiled hubris.

On August 15, 2008, when the Dow [^DJI] was at 11,660 and the Ardour Global Index [^AGIGL] was at 3,370; I offered a short-list of pure play energy storage companies that were likely to benefit from an unprecedented surge in demand for manufactured energy storage devices that will be driven by cleantech, the sixth industrial revolution.

The intervening eight months have been a tough time as the Dow has collapsed to 7,401, a shocking 36.5% decline; and the Ardour Index has plummeted to 1,285, a breathtaking 62% plunge. As a group, my short list of pure play energy storage companies has tracked the Ardour Index and fallen an average of 60%. The following chart compares closing prices of those companies on August 15, 2008 with their closing prices on March 19, 2009.


Combined, the short list companies have a current market capitalization of $2.1 billion. As I previously reported, Federal grants for advanced battery manufacturing will inject $2 billion in new capital into the battery industry over the next two years and grants for electricity delivery and reliability projects are likely to bump that total by another $1 to $1.5 billion. Moreover, effectively unlimited debt financing will be available through an alphabet soup of DOE guaranteed loan programs. In combination, the likely impact on the energy storage sector is mind-boggling.

If one assumes that the DOE does not understand the difference between the leading edge and the bleeding edge and it decides to treat all applicants equally, there is a remote chance that the bleeding edge battery manufacturing companies will have sufficient resources to justify their current market capitalizations when the dust settles, but those market capitalizations are not likely to increase significantly from current nosebleed levels. Instead, the market performance is likely to come from companies that focus on their accomplishments rather than their goals.

At heart I’m an incurable optimist and I firmly believe that “In America we get up in the morning, we go to work and we solve our problems.” (From The Lost Constitution by William Martin). But our problems are not going to be solved by airbrushed centerfolds that thrive on the bleeding edge and promise simple and economically implausible solutions to incredibly complex problems.
