  • Axion Power Concentrator 235: May 12: Axion Power Completes Private Placement For $9 Million And $1 Million [View instapost]
    I've very sorry to take so long to respond back. We have been dealing with a sudden family health issue that has me preoccupied right now.

    I am still heavily involved with advanced transportation systems and I have seen a lack of representation by Axion at key automotive conferences. Last week I participated with the DOE Annual Peer Review and expected to see a presentation by Axion but they did not attend. ??? Very surprised as the DOE announced an increase in funding from 88 to 170M$ (requested) for next year. I've also heard from some of my former contacts that Axion is focusing more on grid and residential systems. I hope this is not true.

    Could you explain your comment on "lack of TG's willing to talk?"

    I will try to do better to be more responsive going forward.

    Ed.

    You can't abuse the battery. The BMS constantly monitors state of health and state of charge and won't let a start/stop cycle happen if the battery cannot support it. So basically, the system is disabled.

    If the battery will hold a charge and start the car, no warranty will be paid. You just get bad gas mileage.

    For fun, I recently test drove a 5 series BMW with start/stop and eassist Buick Lacrosse with start stop. BMW was horrible. Salesman turned off the Eco mode as he got in the car and told me not to use it. I told him this was an important feature for me and turned it back on. It is horrible. System would not work. We drove 15 mins on highway to get it charged and then came off an off ramp. I had to momentarily stop to merge back with traffic and engine shut down, followed by geared start. Horrible. Salesman reiterated that this mode is a problem for them. Then I drove the Buick. Flawless. Hard to tell engine is off unless you look at dial. Plenty of starting/takeoff torque with BAS and engine starts amazingly smooth. Likely retarded ignition couple with turnovers to get manifold pressure down before pressurizing fuel rail.

    Bottom line is that start/stop needs to be better in USA for drivability. These systems with geared starters are not going to work. You are going to need BAS with a second high charge acceptance battery. This could be PbC but I fear Axion has dropped the automotive focus. Very sad.

    I've visited this lab in the past. Daimler uses them for almost all of their battery qualification and testing. Other automobile companies like VW, Audi, BMW, use them for some of their testing. If you can get the weight of the shipment we might be able to figure out if they are PbC or advanced lead acid.

    The amount of power required in and out of the battery is challenging for lithium ion thermally. If you take a hot summer day and then apply the 30 minute charge/discharge requirements NS is talking about, either the Li battery will have to be bypassed or the life will drop dramatically. Not good choices...

    Unfortunately it is more complicated. The PbC battery has self discharge and the vehicle loads are somewhere in the 10-20 mA range but can be 100-150mA for systems like OnStar that periodically transmits/receives even through the car is off. As the PbC battery discharges, the voltage drops so you are losing cranking capability as the SOC drops and the positive plate is forming PbSO4 which increases internal resistance. Now you through in a CCA test at -20C and it is very unlikely you will start the engine. Unfortunate set of conditions but automakers have to design for all scenarios.

    Here is what I found:

    >>The EPS battery is a single unit that results in a more direct energy path, Dhar says. Cells are positioned in an interlocking pattern in a single-cavity configuration, similar to the way bricks are laid to create a wall.

    >>“So you get rid of all these extra connections, these extra lead terminals,” he explains. “You reduce the weight (and) the (electrical) resistance.”

    This sounds like more bipolar nonsense. If you don't deal with the fact that the active material in the negative cannot charge fast, you will go nowhere.

    Seriously, a lead acid battery can produce a short circuit current >1000A until it is dead. But only charges continuously at 2-5A. How do people keep ignoring this imbalance? Every green tech application that I have looked at needs a balance of charge/discharge that is different from the "charge slow for a long time and then use the energy" which is the conventional way to use batteries. This doesn't provide for regenerative braking in vehicles, power spikes from solar/wind, ancillary grid service, etc, etc.

    Conventional use = who cares, charge all the time until you need it.
    Green use = you better have a balance of charge/discharge or you will be useless.

    You can put lipstick on a pig... This technology appears to be useless unless I am missing the majic potion they fed the negative.

    I really like PbC for start-stop because it actually works all of the time. The problem is that lead acid works during the 20 minute test at room temperature but not normally for the customer. Problem is getting the car companies to care about the former.

    Good question. When you recycle lead, you add carbon. It acts as a reducing agent to covert lead oxides and sulfides back to lead. One argument is that you just wouldn't need to add the carbon into the blast or reduction furnaces and you would still be able to recover the acid, plastic, and lead.

    Another answer is to follow what people like RSR are doing in terms of recycling lithium ion cells. They have a cryogenic process to remove carbon and cathode materials very economically. If this is true, then you could recycle the carbon.

    Very good point. Axion's original patent claims a carbon negative electrode that includes leads. Yes, Axion could easily add carbon negative electrodes to lead negative electrodes. However, this doesn't work.

    Axion really needs to show this conclusively. Also - please see extensive posts on other concentrators...

    Queen's is typically one of the best engineering schools (1st or 2nd in ratings every year) in Canada and located in Ontario. They are very aggressive. I have almost no ties to Queen's.

    Sorry for the late reply - I wish this board would email me when I have someone ask me a question.

    Here are the answers:

    0. From above and below, I am no longer a part of Axion. I have not worked for Axion outside some minor help to maintain customers and answer questions since Dec/2010.

    1. I believe TG and management is focused on some of the best commercial possibilities. I believe there are other opportunities and I believe they could be more aggressive. However, it is easy to criticize from the outside and to be fair to Tom and the management team, I might always say they should be more aggressive until they are cash flow positive. On the other hand, these are difficult technical sales campaigns and it always takes a lot of time to see revenue - maybe two years. Look at Maxwell sales - they are now over the hump but it took a good 10 years. I don't think it will take that long with Axion but you need to cast a big net and be aggressive.

    2. I would just be guessing at this point. My real data is two years out and I bet there are people on this forum that are more in tune with Axion's current status than I am.

    3. When will the sales come and will they be able to manage cash flow and avoid bankruptcy? I think this is the big questions. The flooded lead acid battery sales are clearly helping them in this regard but the PbC sales have to start coming.

    4. I do continue to have a financial interest in Axion. It is not as big as it used to be, but this is largely due to my financial adviser's persistence to diversify.

    Yes - have been posting a lot of this. I suspected early that the battery spontaneously went into thermal runaway with no previous indication of a problem. As a pilot, I am not an expert but somewhat familiar with the system on the plane and how they are used. It is very hard to understand how an external influence could have caused this problem as the battery is used very lightly (only to start the APU) and the terminal voltage on the battery was not above 32V or 4.0 VPC. Each cell should be safe to 4.2VPC easily. Boeing admits over 100 batteries failed due to low voltage and SecureAPlane suffered a fire that burned their lab down during battery testing. Yet the batteries still entered service...

    Lots of big problems with the design:

    1. They used LCO instead of NMC or LMO which is standard in the automobile industry because they are safer. (I didn't say safe, just safer)
    2. Cells are large and rectangular with heave metal cases - not good for thermal engineering. Large automotive batteries are flat and do not use heave external packaging to promote thermal management.
    3. Cells are not thermally isolate but put on top of each other. Automotive packs use isolation such as thin cells space apart with aluminum plates that are connected to cooling systems. Not of which was included in the battery design.
    4. GS Yuasa was somewhat forced on Boeing due to Japanese content to get sales to Japanese Airlines. It is likely the best battery was not chosen - what about LG, Sanyo, Moli, EnerDel, A123, etc. ???

    Based on what is being shown by the NTSB, CAT scans and SEM/EDS, I think they are looking for contaminants in the battery. Iron contamination due to a wearing bearing caused the massive Sony recall. Based on how the battery was being used, it is hard to understand how the battery went into thermal runaway unless there is a mfg defect.
