CleanTechnica reader Amos Batto caught some very interesting notes on Chery’s solid-state batteries. Following up on our story about the company developing the first solid-state battery factory in the world (1 GWh of capacity), it seemed prudent to publish his comment as a standalone article. We will surely be referencing it in the future. Thank you, Amos.

I can’t find much info about these batteries by Anwa New Energy, but Anwa was previously described as working on “semi-solid state” batteries. CarNewsChina says: “According to Anwa, the company is able to shorten the battery production process from 11 steps to 5. This eliminates the processes of baking, compaction, slitting, die-cutting, drying, and liquid injection. Also, it involves dry manufacturing of the positive and negative electrodes. The result is a 30% reduction in fixed asset investment and a 20% reduction in energy consumption for manufacturing.”
The fact that Gotion Hi-Tech is also invested in Anwa New Energy gives me some confidence that these batteries are legit. They originally said that the energy density would start at 340 Wh/kg, but now they are starting production at 280 Wh/kg, which is the energy density of today’s higher-end conventional NMC batteries.
Chery is scaling back its claims of energy density. In October, the company claimed: “With solid-state batteries, Chery announced a timeline of achieving an energy density of 400 Wh/kg this year, increasing to 600 Wh/kg in 2025, with the first car application happening in 2026. This will be followed by initial batch production in 2027. The company claims it will give EVs a range of 1500 km.”
I think that Chery is now saying it will start at 280 Wh/kg rather than 400 Wh/kg shows that it is actually planning on doing real production.
