A lesser-known company, Jiangxi Judian, began construction on August 8 on a solid-state lithium battery project with an annual capacity of up to 10 GWh.

Shenzhen Fuxin, founded in 2019, is a supplier of energy storage systems and indirectly holds Jiangxi Judian.

Currently, new energy vehicles (NEVs) mainly use liquid lithium batteries, but energy density is approaching its limit, and solid-state batteries are seen as a new technology capable of achieving higher energy density.

When Nio (NYSE: NIO) launched its flagship sedan, the Nio ET7, at the Nio Day 2020 event on January 9, 2021, it unveiled a 150-kWh semi-solid-state battery that it said could give the vehicle a range of more than 1,000 kilometers.

After that, solid-state batteries began to receive widespread attention as a new technology.

Solid-state electrolytes are structurally more stable, preventing short-circuiting of the battery, and are the best battery solution for balancing safety and energy density, market research firm TrendForce said in a report last month.

As automakers accelerate their investment and research and development in solid-state batteries, all-solid-state batteries with high-activity materials are expected to begin mass production around 2030 to 2035, TrendForce said.

By then, the energy density of lithium batteries could reach 500 Wh/kg, providing electric vehicles with a range that would be 2~3 times that of liquid lithium batteries, matching the range of fuel vehicles, the report said.

EVs with all-solid-state batteries expected to be in mass production by 2030, doubling range from today, TrendForce says
