Battery claims
The following link is to the complete list of claims I have been compiling.

https://martindavidwalker.blogspot.com/2024/09/battery-claims.html

The new claims in the last week are as follows.

November 24th 2024, Goliath moving towards a minimum viable product solid state battery
Perhaps not the strongest claim ever, but a real timeline, not something intangible in 3 years.

November 22nd 2024, Honda going to produce solid-state batteries
Still in the “mock production line” phase.

November 20th 2024, first solid state production line.
A road map promising 500wh/kg in a couple of years.

I think the Estima needs adding...practical and long lasting

November 30th 2024, BYD unveil sodium ion battery for grid storage
“Sodium-ion batteries are much cheaper as their raw material is abundant, and they can offer longer lifespan with higher discharge rate even when cold. To top it all off, they are safer than lithium batteries whose piercing, exposure to high temperatures, or manufacturing defects can result in uncontrollable thermal runaway.”

November 26th 2024 another flight capable battery
https://newatlas.com/energy/ghove-lithium-sulfur-battery-evtol/
November 25th 2024 another update on Cheri/SAIC solid-state production claims
The claim is for a 45,000 life cycle, in perspective a 1000 lifecycle will take a car 300,000 miles. What I'm not reading about is the cost of the battery.

The new claims in the last week are as follows.

December 6th 2024, Nickel Hydrogen batteries being piloted for grid storage
Nickel Hydrogen offers the advantage of in this case a high cycle life of 30,000. But this is offset by the fact they are very expensive, use Nickel and suffer from a high self discharge rate of 1% a day.

December 5th 2024, CATL announce 200wh/kg sodium ion batteries
That's enough for cheaper batteries and cars with longer range than current LFP batteries. Plus of course none of the overblown issues of lithium based batteries.

https://arstechnica.com/cars/2024/12/lower-cost-sodium-ion-batteries-are-finally-having-their-moment/
December 5th 2024, Quantumscape reach another solid-state production milestone
At 301wh/kg these are the most energy dense batteries in the works. But since most EVs currently have batteries of less than 200wh/kg it could mean current 250 miles range EVs getting 300 miles whilst becoming lighter than ICE cars.

December 11th 2024, Inlyte announce very long life cycle Iron Sodium batteries
The startup is targeting commercial demonstration projects in 2025 and large-scale U.S. manufacturing by early 2027.
