One of the post pointed out that GM did not pick A123 in the past and references an article. See below if interested.

Re: GM’s China Dream Falters Because Of Bad Batteries / Chinese-built EVs not as easy as A123
"The batteries that its in-country supplier A123 has been producing are not up to specification and can not be used as originally intended."

A123 and GM have a checkered past. A123 used to be a US company and GM was considering using them for the original Volt batteries. But LG Chem has a more robust profile with more commercial battery experience, so GM went there. GM did briefly use an A123 pack (bottom-plate-cooled!) for the first Spark EVs, but after China’s Wanxiang Group bought A123, GM used cells made by LG Chem with a very Volt-esque module design and cooling concept.
So GM finally trusts the now-Chinese-owned A123 for a real production battery and gets burned. Probably a lot of veteran GM and LG Chem battery engineers in Detroit muttering “I told you so”

Was wondering about GM's battery issues in China which delayed their launch. Interesting stuff. A123 batteries were known for more stable chemistries than Lithium Ion. At the time of my EV conversion project they were cheaper and more plentiful. All this EV stuff was new to me, and I really liked their stability for safety. Sounds like these versions have a new twist, nanoscale powder.
