Some more info on NIO's semi solid state batteries that are scheduled to be in production cars later this year:

https://www.autoevolution.com/news/nio- ... 75124.html
According to what Li said at the time, this semi-SSB would comprise “in-situ solidified solid-liquid electrolyte, inorganic pre-lithiated carbon-silicon anode, and nano-scale ultra-high nickel cathode.”
Of interest is the investment by Huawei and Xiaomi which means we could see the tech in mobile computing devices and micro-mobility.

1.15 kwh per liter (oh yeah!!)
Claimed.

We know about battery claims.
This is to express my gratitude to Justin of Grin Technologies for his extraordinary measures to save this forum for the benefit of all.

Here are some you can buy:

https://www.foxtechfpv.com/foxtech-diam ... ttery.html

There is a man who tested them in this thread named RichardG:

https://community.openppg.com/t/new-bat ... ty/2274/43
Foxtech:
The ultimate, money-no-object highest power density per weight is the Foxtech Diamond. A similar pack configuration to the Bonkas. I have posted my capacity investigation on these in this thread above.
These are what Foxtech call semi-solid lithium. They have impressive energy density specifications, which my testing has confirmed.

4 x Foxtech Diamond gives 7% more energy for 15% less weight than 4 x Bonkas.
But costs 28% more.
The Foxtechs are very difficult to get hold of ( but I now have four!)
They need re-wiring with thicker cable to work with OpenPPG.
The Foxtech’s longevity is yet to be tested.
They are currently only available in a 6S configuration.

Actually they didn't claim 1.15 kWh per liter. I thought I had derived that from the energy capacity vs. volume, but I made. a mistake and 1.15 liters is the volume.

570 watt hours/1.15 liters gives .496 kWh per liter.

If anyone is wondering the semi-solid state batteries sold by Foxtech have specs which match up exactly with those of solidstatelion.com (the company which is making the semi solid state batteries for NIO).

An example would be to compare this one:

http://www.solidstatelion.com/en/product_page/294.html

....to the 7s 22000mAh in the Foxtech chart below:

(Both have exactly the same dimensions and exactly the same weight. It seems obvious that Foxtech is buying these from solidstatelion.com and rebranding)

Interesting times watching the news releases on EV battery tech. Reminds me of a food fight. Tremendous amounts of investment and a turf fight to boot. Interested in seeing how the 46-80 format proves out and the LFP format that develops over the near future. Looking at the numbers, the lowest cost, and most reliable will most likely own it as most of the current designs will not find a market unless they show much better performance characteristics that justify the added expense.

If past PR announcements are any indication then 90% will prove to be "all hat and no cattle".
The more I learn the more obvious the immensity of my ignorance becomes.

Apparently solid state battery design works with both LFP and high nickel cathode designs:

Here is something I thought was very interesting while I was researching the NIO semi solid state batteries:

570 watt hours/1.15 liters gives .496 kWh per liter.
Comparison:

A Samsung 25R cell has a volumetric density of 527 wh per liter. However, once assembled into a EM3ev rectangular battery pack volumetric density drops to around 235 Wh per liter.

https://em3ev.com/shop/50v-14s7p-rectan ... tery-pack/

So the foxtech semi-solid state batteries at 496 Wh per liter have more than twice the volume density as a well designed 18650 cell battery pack using the Samsung 25R. (Furthermore, Foxtech lists the semi state battery packs up to 14S with 30Ah and these larger packs still have roughly the same Wh per volume as the smaller packs. e.g. 14S30Ah has 498 Wh per liter.)
