BYD and CATL form Chinese powerhouse for solid-state batteries for electric vehicles

Chinese automakers and battery giants including BYD, CATL and NIO are joining forces to form an “all-star” lineup to develop all-solid-state batteries for electric vehicles.

In a move that could revolutionize the electric vehicle market, China’s top auto and battery makers are forming an alliance to commercialize all solid-state batteries.

According to Nikkei AsiaThe China All-Solid-State Battery Collaborative Innovation Platform, or CASIP, was established last month.

The government-led alliance brings together academics and industry leaders, such as BYD and CATL, to build a solid-state electric vehicle battery supply chain.

China already dominates the global electric vehicle battery market, with BYD and CATL alone accounting for more than 50%. Data from SNE Research (via Bloomberg) shows that CATL sales in the United States and Europe doubled last year.

BYD and CATL batteries are used by Tesla, BMW, Toyota, Mercedes-Benz, Kia, Ford and other major electric vehicle manufacturers.

China seeks to stay at the forefront by boosting research and development of next-generation electric vehicle battery technologies, including solid-state ones.

“We need to be prepared for the risk that all-solid-state battery technology could reverse” China’s advantage in the electric vehicle battery market, said Ouyang Minggao, a professor at Tsinghua University.

Minggao, who specializes in automotive technology development, stressed the importance of bringing together industry leaders. CASIP will focus on commercializing electric vehicles equipped with solid-state batteries and establishing a supply chain.

The goal is to develop next-generation EV batteries that will be globally competitive. The alliance includes leading battery manufacturers including CATL, BYD subsidiary FinDreams, CALB, EVE Energy and Gotion High-tech. Automakers, such as NIO and BYD, will also join.

An alliance with BYD and CATL is interesting, as they compete in the LFP battery market. The report notes that CATL also sued CALB and SVOLT Energy Tech for patent infringement.

Government members will include, among others, the Ministry of Industry and Information Technology, the Ministry of Science and Technology, the Ministry of Science and Technology and the National Energy Administration .

Chen Qingtai, director of China EV100, argued that solid-state batteries for electric vehicles can change the energy balance of the industry. Working together will enable China to become an “automotive power”.

Although many others, including Toyota, have promised to commercialize solid-state electric battery technology for years, there is still little to show for it.

Toyota holds more than 1,300 patents for all-solid-state batteries, while Chinese companies own fewer than 100. The alliance aims to ensure China stays ahead of the market.

Electrek’s point of view

Six of the world’s ten largest battery makers, including BYD and CATL, working together to develop solid-state batteries for electric vehicles will be ones to watch.

These companies are already leading the industry to new heights. With decades of combined experience, I wouldn’t bet against CASIP.

Even though Toyota claims to have discovered a “technology breakthrough” with solid-state batteries, the automaker doesn’t plan to bring it to market until 2027 or 2028. Even then, it will be extremely limited if it happens.

A recent Toyota Schedule post explained that production is expected “for 2030 and beyond.” Meanwhile, South Korean market leaders including Hyundai, Samsung and LG formed an alliance last summer to boost electric vehicle sales.

Hyundai has filed several patents for all-solid-state EV batteries. Can South Korea give China a hard time? The race to commercialize solid-state batteries for electric vehicles will be exciting to watch. We will keep you informed of the latest developments.
