Gotion High-Tech Announces Solid State Batteries with 400 Wh/kg Energy Density

Chinese battery manufacturer Gotion High-Tech announced its new goals for solid-state batteries, which are an important step in electric vehicle technologies. The company plans to increase the energy density of the Jinshi cells it has developed to 400 Wh/kg.

The company, of which Volkswagen is the largest shareholder, shared current data about this new technology at the World Manufacturing Convention 2026 event held in Hefei. The energy density value, previously announced as 350 Wh/kg, was moved to a higher point with the studies carried out.

Gotion does not keep its current 350 Wh/kg capacity cells only in laboratory environments. Full solid state cells produced on the pilot production line with an annual capacity of 0.2 GWh, which was commissioned in 2025, were road tested on real vehicles.

The company is preparing for a larger scale on the production side. In March 2026, the design of the solid-state battery line with an annual production capacity of 2 GWh was completed.

Gotion had previously announced that it aims to start small-scale production in 2027. Around 2030 is pointed out for the transition to mass production.

Work continues to overcome the material problems encountered in the transition of technology to mass production. In this context, the company signed a cooperation agreement with BASF on high-performance solid-state battery materials at the beginning of 2026.

Gotion, which has 20 production facilities around the world, reached 4.61 GWh battery installation volume as of August 2026. With this performance, the company ranks fifth in the Chinese battery market.

A new level has also been set in terms of cost, which is one of the biggest obstacles to solid-state batteries. Gotion plans to drop to 1 yuan/Wh in the long term.

This figure corresponds to approximately 150 dollars/kWh. However, this target still represents more than double the cost of the average LFP cells used today in China.

Jinshi cells also pass safety tests. It was reported that there was no smoke or flame in the cells during the drilling and high temperature tests.

The solid electrolyte structure offers a different safety architecture than traditional liquid electrolyte lithium ion cells. The cooperation with Volkswagen expands to include production and supply structuring in Europe.
