> Also, a lithium-iron-phosphate battery is a lithium-ion battery, in that the electrolyte works by lithium ionic conduction. The appropriate contrast would be "lithium-nickel".

Correct, I want to point out that John Goodenough was responsible for the basic research which lead to all lithium-ion batteries.

I explicitly intended LiFePO to be included, and I hope for a variety of reasons that it's much more popular than cobalt-heavy formulas in ten years.

Only now do I realise that "Goodenough" is a real person's name, and neither a placeholder name nor a case of Emphasis Via Capital Letters:

I have been interested in the technology from TexPower:

They offer a lithium-nickel chemistry without cobalt. If it can be proven in practice, it would allow comparable density to the best car batteries in a scalable chemistry. The founder is a researcher at the University of Texas who wrote several papers on the chemistry:
