Battery claims
July 18th
This follows on from previous news that a new manager was given this deadline. But there never can be a set time in which break throughs can be made and no one is standing still on batteries.

This story not only talks about a high mileage battery getting a warranty replacement but about growing calls for battery warranties to increase to 15 years at 85% capacity. This would eliminate the last concerns about battery life. Notably the car was a later Model S with a more reliable battery pack than earlier cars. It can't be emphasised enough how young the modern history of EV batteries is. From nothing 20 years ago to where we are today. The development curve for making a really real world reliable for decades battery hasn't even spanned that time period.

SAKUU PCC cheap high density solid state 370wh/kg using a lot less packaging. Not so great on cycle life, but game changing. But on the subject of life cycle a 1000 lifetime might be poor, but in a 400 range car thats 400,000 miles. It really wouldn't matter that much if it was 500 cycles!

June 17th
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.
https://cnevpost.com/2024/06/17/welion-sees-31-pct-increase-installations-may-2024/
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.

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.

This story not only talks about a high mileage battery getting a warranty replacement but about growing calls for battery warranties to increase to 15 years at 85% capacity. This would eliminate the last concerns about battery life. Notably the car was a later Model S with a more reliable battery pack than earlier cars. It can't be emphasised enough how young the modern history of EV batteries is. From nothing 20 years ago to where we are today. The development curve for making a really real world reliable for decades battery hasn't even spanned that time period.

SAKUU PCC cheap high density solid state 370wh/kg using a lot less packaging. Not so great on cycle life, but game changing. But on the subject of life cycle a 1000 lifetime might be poor, but in a 400 range car thats 400,000 miles. It really wouldn't matter that much if it was 500 cycles!

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.
https://interestingengineering.com/transportation/farasis-energy-ev-battery-handles-22f-to-149f
_____________
June 17th
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.
https://cnevpost.com/2024/06/17/welion-sees-31-pct-increase-installations-may-2024/
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.

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.

Forge battery claiming sampling on a 300wh/kg at cell level battery with 10 minute charging an reduced manufacturing costs. Factory plans are for mass production in 2026.
It's interesting to compare this announcement which is perhaps 20% improvement or less on current available best is class batteries with more hyperbolic "game changing" claims.
In my view it doesn't take very much to change the game. If these batteries could replace LFP batteries in cars with 225 miles range, those cars would have over 300 miles range and that's a tipping point without solid-state being needed.

This story not only talks about a high mileage battery getting a warranty replacement but about growing calls for battery warranties to increase to 15 years at 85% capacity. This would eliminate the last concerns about battery life. Notably the car was a later Model S with a more reliable battery pack than earlier cars. It can't be emphasised enough how young the modern history of EV batteries is. From nothing 20 years ago to where we are today. The development curve for making a really real world reliable for decades battery hasn't even spanned that time period.

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.
https://cnevpost.com/2024/06/17/welion-sees-31-pct-increase-installations-may-2024/
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.

Battery claims
August 15th
China based Eve Energy reveals a very fast charging NCM battery pack targeting 400wh/kg by 2028. I still find myself struggling with why car users would care? It's not gain if you spend 5 minutes at a charger rather than 3 minutes at the pump and then have to park up for the toilets. Plus whilst the harm in fast charging is it appears greatly exaggerated I have never heard anyone claim It's totally harmless.

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.
https://cnevpost.com/2024/06/17/welion-sees-31-pct-increase-installations-may-2024/

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?

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.

Yokohama National University achieving high energy density with manganese anodes, note the density of 820wh/kg quoted isn't a cell level density let alone pack level.

Plus whilst the harm in fast charging is it appears greatly exaggerated I have never heard anyone claim It's totally harmless.

The CATL 500wh/kg condensed battery promises to power long range aircraft. An 8 tonne aircraft translates I guess to carrying 25 people. That's pretty "real" and undoubtedly would change aviation.

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.

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.
