South Korean media: Chinese companies are striving to produce all-solid-state batteries this year, can they run 1500 kilometers?

On June 20, the South Korean media "Digital Today" published an article stating that all-solid-state batteries are attracting attention as a key technology to change the landscape of the electric vehicle market. Changan Automobile has set a target to achieve production this year.

Changan Automobile announced that it will begin production of solid-state batteries with energy density as high as 400Wh/kg and full charge range exceeding 1500 kilometers by the end of this year, and plans to install them in mass-produced models starting from 2027. The company claims that it has improved the safety of solid-state batteries by 70% using artificial intelligence (AI) remote diagnostic technology, and ultimately plans to completely eliminate the thermal runaway problem existing in current lithium-ion batteries.

In addition to Changan Automobile, the world's largest electric vehicle battery manufacturer CATL and Chinese electric vehicle manufacturer BYD also aim for the production of all-solid-state batteries. In April this year, CATL's Chief Scientist Wu Kai announced that the company will start small-scale production of all-solid-state batteries in 2027; in February, BYD also stated that the company will begin testing all-solid-state batteries in 2027. However, large-scale commercialization may not happen until after 2030.

All-solid-state batteries replace liquid electrolytes with solid electrolytes, making them more heat-resistant and less prone to damage when hit. Relevant experiments show that it has higher energy density, faster charging speed, and lighter weight than current lithium-ion batteries. It can also replace the heavy safety devices required by current electric vehicles, reducing manufacturing costs.

Meanwhile, as the United States increases tariffs on Chinese electric vehicles, the US may fall behind in the technological race. General Motors and Ford are developing manganese-based batteries that combine the advantages of low-cost LFP batteries and high-performance NMC batteries, but there is an evaluation that it is difficult to keep up with the pace of technological progress of Chinese enterprises.
