Yeah, that's LiFePO4, AKA LFP, LiPo or Lithium Iron Phosphate.  It's
perfect for large-scale consumer packs.  Qualities (vs. Lithium Cobalt):
* No exotic or poisonous materials to source or recycle
* Longer life, with more consistent performance than other technologies
* Does not catch fire when abused

It looks like the new Lithium Titanate anode technology is compatible with
LFP cathode tech, which would give a battery with all of LFP's qualities,
and with ultracapacitor-like surge performance.
Looks like ALTI might be working that angle, along with revenues from
licensing their renal-failure treatment.

Oh, and A123 got a nice contract with GM last month.

Me too.

Smart man.  And very impressive that he was able to buy such a large share
of a Chinese company.
