Interesting post on fb by an ex Brit now US, EV SUV driver...
Honda Nissan and Mitsubishi merging.

Comments saying 1.that it is in effect the destruction of Nissan
2.China is making huge strides environmentally and US car makers despite having a large market share in China are losing major business
And 3, that Chinese battery electric capital equipment is cheap but doesn't last., so they think that China's over production is a short term threat.

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.
January 3rd 2024 high density sodium batteries
At face value another break through that makes EVs cheaper than ICE cars.

January 2nd, 2024 CATL launching swappable batteries and charging partnerships.
People including me are quick to say the swappable boat has sailed. But CATL thinks differently and it occurs to me that there are a lot of niche markets.

Most of the little scooters (vespa type things) in China have swappable batteries

Having them battery powered, with interchangeable batteries would certainly make them quieter, but need to have sound so they don't sneak up on people.

Definitely scary in China, could be on the road one minute pavement next. They’re loonies

The new claims in the last week are as follows.
January 5th 2025, Claims of 480wh/kg Zinc batteries
I almost didn't include this as it reads too much like a puff piece. But if true would be another game changer. Game changer is a phrase I over use without apology. Battery tech needs little improvement now to create a cheap light EV with if you want it ICE like range.

norway is getting close to all EV for new vehicles and has a high ev on the road share already

rational planning is usually a good idea

removing applications that have no progression towards a harvest that needs grid distribution might get some of the nearly ready stuff connected

the grid scale harvests, the battery banks to buffer excess wind/solar/the bigger versions of the shetland array etc have a better claimto early connection to the upgraded grid than unfinished nukes or assorted zombie plans that are as yet unfunded etc

ps ev needs user end grid scale distribution sorting as well

pps the "production" price of harvested is less and with wind 60% less than from fossil or nukes

The new claims in the last week are as follows.
January 16th 2025, ProLogium Unveils Fast Charging Inorganic Battery At CES 2025
Claims of cheap production, low temperature performance and 380wh/kg energy density with a target of 450wh/kg. This is more than double the energy density of typical LFP batteries. It is worth thinking not just about the range and cost implications of half the materials but also the reduced carbon footprint.

https://cleantechnica.com/2025/01/10/prologium-unveils-fast-charging-inorganic-battery-at-ces-2025/
January 15th 2025, Samsung solid-state battery with highest energy density set for mass production
A 2027 cheap mass production claim. My last Samsung report was last July and the batteries were said to be 500wh/kg with potential to go higher. Still not much solid detail though. 2027 now achieves my general rule of ignore it as hyperbole at the 3 years or more mark!

https://www.notebookcheck.net/Samsung-solid-state-battery-with-highest-energy-density-set-for-mass-production.947578.0.html
January 15th 2025, The struggle for mass market sodium batteries
Less an advance more economic lessons, though frankly I see the Chinese getting sodium through the hurdles. They take a longer term economic view.

a slight wild card but

rokon

they make petrol ones, not the point (noisy and petrol is not ideal)

2 wheel drive, high torque, their ones only need 7HP(the drive train eats quite a bit of that as it is mechanical and relatively heavy)

"fly by wire", 2 hub motors(see koenigssegg for the type of motor that has an ace power to wt ratio), good batteries are becoming increasingly available

a very off road machine, better than a quadbike or rear drive bike, (or a rokon), and plausibly carrying an energy harvest kit if extended travel is planned(see carry capacity) seems plausible

development might cost a bit, once it was worked out a good design could be relatively cheap enough for a "mule" type of transport

much like the C90 changed urban noodle delivery, and much else, a leccy version of a rokon could transform could "challenging"rural travel

Sounds as if it could be useful on rough terrain, and being a motorcycle, even if heavy, easier to get off if it starts to topple. The idea of storing water/fuel in the wheels is interesting and should add to stability. As you suggest, an electric version would be very interesting, especially if it came with solar recharging kit.

We have had a bit of a break no doubt due to Chinese New Year.

The new claims in the last week are as follows.
February 16th 2025, BYD to start sampling solid-state batteries in 2027
Like many others they are targeting larger production in 2030 but cite costs as an issue
