I expect that like computers, it will sort itself out. In the early days of desk top computers, one make of computer wouldn't 'talk' to printers, or anything else belonging to another make. Now virtually all are interchangeable.

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.
June 27th 2025, GM working on three new battery technologies
GM are working on Solid-state state, Sodium and Lithium Manganese Rich batteries. All of that has been reported previously but it does emphasise that not only do they recognise the future is in batteries but also the importance of vertical integration.
I'm happy to be corrected but 5 years ago it felt to me like legacy auto were having to scrabble around for batteries probably paying through the nose for the worst batteries.

June 27th 2025, Vanadium Redox Flow batteries for grid storage
Less an claim and more an “informational” that there are lots of alternatives to Lithium when it comes to grid storage. All batteries have specific properties and the super power of Vanadium Redox Flow batteries is long term storage.

June 27th 2025, longer life Zinc ion batteries
Claims of a 5000 cycle life and hence a contender for grid storage.

June 24th 2025, Quantumscape speeds up solid-state production
These are lithium metal solid-state batteries entering an advanced sampling phase. Based on earlier press releases these would be 300wh/kg energy density.

at least a few of the options will become useful

The new claims in the last week are as follows.
July 5th 2025, Chery backed company samples solid-state batteries
This again is a “we have a production line” claim with promises of progressing from 300wh/kg to 400wh/kg and then to 500wh/kg. Assuming accessible costs any of these numbers would be game changing.
A note on solid-state costs. I don't think it serves the interests of companies to not suggest initial prices will be high. Would CATL really want to say that in a couple of years you can have a 80kwh solid-state battery for the price of a 50kwh lithium ion battery now? They are not going to say that! But obviously raw materials costs would have likely reduced.
