Battery claims
June 22nd
Farasis Energy joining the list of semi solid-state batteries. This one with a 5000 life cycle to 70% and good temperature performance. The energy density is implied to be high. No mention of costs, manufacturing or time scales.

Production of the WeLion 360 wh/kg ( update 260 wh/kg at pack level) semi solid-state battery continues to increase. These are 150kwh batteries but at a $40,000 cost. I have no information on how that cost might reduce, but I'd invite people to consider that a 50kwh battery of this type would give a car a decent range and it is not at all unreasonable to assume volume production would halve costs.

Cycle life appears to be 20% degradation over 1000 cycles. That's not over impressive but 1000 x 50 x 5 e.g. a 50kwh battery getting 5 miles a kw would reach 250,000 miles which isn't terrible.

TDK claim small solid-state batteries with 1000wh/l a 250% improvement on existing batteries.
Due to ceramic materials, the batteries are not considered scalable even to smart phone sizes.

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.

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.
