Mass production in 2025, Changan Automobile reveals latest solid-state battery plan

According to news on December 3, Changan Automobile recently revealed the latest progress of its solid-state battery plan in its latest investor relations activity record.

Changan Automobile is currently actively developing new electrolyte materials for semi-solid batteries and solid-state batteries, as well as key processes. According to the understanding, the company plans to gradually promote the development of solid-state batteries based on vehicle demand, and plans to gradually mass-produce applications from 2025.

According to the editor’s understanding, Changan Automobile is committed to improving the research and development of solid-state batteries. The gravimetric energy density of the battery is expected to reach 350-500 Wh/kg, and the volumetric energy density is also expected to reach 750-1000 Wh/L. It is expected that this new type of battery will be fully popularized by 2030.

In addition, Changan Automobile is also designing prototype cells for new batteries such as lithium-sulfur batteries and metal batteries. It is reported that the energy density of these new batteries is expected to exceed 1300-1500 Wh/kg, and they strive to achieve on-board applications in 2035.

Times Changan Power Battery Co., Ltd., a joint venture between Changan Automobile, CATL and Shenlan Automobile, officially launched an 87 ampere-hour (Ah) standard battery product on November 24. These battery products will also incorporate 4C fast charging technology, making the charging efficiency comparable to that of fuel vehicles, from 20% to 80% in just 10 minutes.

Changan Automobile’s continuous innovation and efforts in the field of new energy have provided strong driving support for the future development of automotive technology.
