A pretty busy week in terms of new developments and updates. An interesting development a day or thereabouts.
June 15th
Throwing this in the mix as we care about batteries mostly because of range, but 20% better efficiency is the same as 20% better battery. It equally important and oft forgotten.

Still not good news of the 4860 front, still seems like an expensive impossible to repair battery undercut by third parties. Can a new head really defy reality and deliver a cheaper product by end of year when the competition is far from standing still?

Latest study that suggests little damage is done fast charging a modern EV. It is not however split out by battery chemistry or charging to 100% rather than 80% and of course the data for fast charging remains sparse as few people regularly fast charge.

Another Factorial update superceding the June 7th article on them sampling cells to Mercedes. The aim is a 90kwh battery driving 600 miles range whilst being 30% less in weight and size.

Liquid air energy storage plant being built in the UK. Claimed to be economical at scale. As ever this sort of development begs the question of what is "really" economic? Ripping coal from the ground in Wales was nicely economic for mine owners, but the slag heaps are not economic for us now. Lithium and Cobalt are also "nicely economic" and not the utter horror fossil fuel companies would have us believe, but even materials that will be recycled come at an environmental and social cost.
