There has been some speculation in the post threads that GM is more excited about A123 batteries. I wonder what the difference in the batteries is. Lutz has said that both batteries have extreme strengths and some weaknesses. Does anyone have any idea what they would be?

I am quite ignorant about anything scientific, but I have a feeling that the A123 chemistry has a higher potential than the CPI ones. However, CPI may have higher production capacity and perhaps a lower short-term cost. I say this because a lot of the talk about A123 has been a revolutionary improvement in lithium battery technology. Maybe CPI, being lower-tech is cheaper and easier to make. I base that on CPI having their batteries sent to GM sooner.

I could be completely off-base in my speculation so I want to hear what others think.
