September 15th 2024, Catl launch 1.5 million km bus batteries
These batteries have a 10 year 1 million km warranty and are projected for a “service life” of 15 years which I feel might be misinterpreted as some kind of time limit on battery life where really it's a projection for a battery clocking up more than 1 million km.

September 14th 2024, fly wheel storage goes live in China
No one has crunched the numbers here, but especially as it is the first of its kind I suspect it would have been expensive.
This though symbolises the problem of competing with fossil fuels in a market economy. Fossil fuel may be cheap at point of use, but the hidden costs are incomprehensibly high, the literally destruction of the eco system.
But despite this we demand renewables to be cheaper than fossil fuels.

September 11th 2024, Japan roll out 2.4 billion in domestic EV subsidies
If any final admission was needed, then this is it. The future is with batteries, everyone including Toyota with any clue knows this.

September 11th 2024, Ilika goliath solid-state battery prototypes demonstrate superior safety.
Solid-state prototypes that are being sampled to OEMs.
https://www.ilika.com/latest-news/goliath-prototypes-demonstrate-superior-safety
September 11th 2024, Panasonic to begin mass production of 4680 battery cells
It's important to remember that 4860 is just a specification like saying an AA battery. The real questions will be how much? And how good? In comparison with what Tesla is able to do with its thus far problematic 4860 production.
September 9th 2024, Envsision produces the highest energy density grid storage battery
Grid storage batteries continue their journey towards commoditization. A lot of people think that Tesla will continue to make massive profits from grid storage, but I fail to see how long term.

September 7th 2024, Wartsila releases new grid storage battery.
This is in the list almost because it isn't very interesting and that serves to highlight the growing commoditization of grid level batteries.
https://www.pv-magazine.com/2024/09/05/wartsila-releases-new-utility-scale-battery/
________
September 6th 2024, Group 1 unveils potassium ion battery
I have found little technical material on this, but they say it is being sampled to cell manufacturers. Batteries free of lithium, nickel, copper and cobalt are clearly a good thing. The release places energy density at between 160 and 180wh/kg on a par with older LFP batteries.
______
September 5th 2024, Nio signs worldwide battery swap partnership deal
The fact that companies continue to pursue battery swapping as a solution is interesting. But like we have petrol and diesel coexisting there is no intrinsic reason why battery swapping shouldn't have a place. A swappable battery can still be charged without swapping and swapping has a number of potential advantages.
You don't own what is the expensive point of failure in an EV.
You should be able to choose battery size, only swapping to a heavier battery when needed.
If you can't charge at home it's the familiar solution to ICE drivers.
It would be a bit faster than even very fast charging EVs.
The merits of these points are very debatable, but hey people will pay £500 to go to an Oasis gig!

_________
September 4th 2024, MG to release car with possibly a 368wh/kg “solid-state” battery in 2025.
The article implies it will be a battery jointly developed in a partnership between SAIC and Chinese battery specialist, Jiangsu Qingtao and actually semi solid-state. SAIC has claimed their batteries will be 30% cheaper than LFP in the long term.
Like many announcements in recent weeks these energy densities would create long range EVs lighter than ICE cars.

__________
September 3rd 2024, Enerpoly opens first Zinc-ion mega factory for grid storage.
Batteries meant to be cheaper and longer lasting than Lithium based batteries. The article does contain misinformation that lithium batteries only “manage 12 years”.
https://newatlas.com/energy/enerpoly-zinc-ion-battery-megafactory/
__________
September 1st 2024, Another rebuttal to the idea that batteries cannot be recycled in an environmentally frequency cost effective fashion.
___________
August 31st 2024, Study shows that how a battery is initially charged can have a dramatic effect on battery life.
With a very high current initial charge stabilizing the “SEI” layer on the negative electrode. Two obvious points though, what chemistries does this apply to? And consider the source as this research is funded by Toyota.

_______
August 31st 2024, Swansea University collaborates in the development of a graphene foil
The foil highly conductive to heat and electricity could replace copper and aluminum current collectors in batteries, increasing energy density and forming an oxygen barrier protecting against thermal runaway.
_______
August 30th 2024 , ORNL with a claim of a thin electrode separator membrane that could give solid-state batteries 500 wh/kg density.
Of course there are many solid-state claims at the moment and this one is still in the lab.
_______
August 30th 2024, Chinese company Penghui Energy promise solid-state mass production of a “cheap” possibly 300 wh/kg battery in 2026.
The 600 cycle life gives cars an approximately 300,000 mile life. The price claim is that “it costs just 15% more than your average standard battery cell used in today's EVs” but that's such a moving goal post that it could be twice as expensive or more than some new LFP batteries.
__________
August 28th 2024, 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. But we are talking game changing numbers in a no Cobalt battery. A reminder here that I aim to keep these battery updates in the realms of real rather than hyperbole, from lab to production is a long road. This particular claim is sufficiently interesting to get a mention but might drop off the list unless it firms up.
https://www.eurekalert.org/news-releases/1055354?
___________
August 19th 2024, Amazing cost and density claims from Paraclete at $35kwh and 520wh/kg
Note this is talked about in reference to the anode only.
https://www.electrive.com/2024/08/19/paraclete-announces-battery-density-breakthrough/
______
August 15th 2024, 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.
_______
August 14th 2024, Lithium metal batteries from SES passes stringent safety tests for a 400wh/kg battery.
Cost and production hurdles aside it's another portent of EVs with 350 miles of range that would be lighter than ICE cars.
https://www.electrive.com/2024/08/13/ses-reports-progress-with-lithium-metal-battery/
_______
August 9th 2024, An expansion of sodium ion batteries on the Chinese grid.
_______
August 7th 2024, Forge battery claiming sampling on a 300wh/kg at cell level battery with 10 minute charging and 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.
_________
August 6th 2024, Batteries have dropped in price 90% in 15 years
Note this that's out of date! Could be 95% by the end of 2024. Yet some people think price parity is 2027.

________
July 31st 2024, Samsung are sampling expensive solid state batteries at 500 wh/kg density

________
July 16th 2024, 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 emphasized 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.

_________
July 3rd 2024, 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 2024, Production of the WeLion 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.

June 13th 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? 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.
