Chery announces breakthrough in solid-state battery development
Electric vehicles equipped with this technology could theoretically travel more than 1,500 km on a single charge, although the actual range is expected to be 1,300 km. The company reaffirmed its plan to launch a pilot operation in 2026 and roll out a wider market launch in 2027. According to Carnewschina, “Chery Solid-State Battery Research Institute developed the module and adopted an in-situ polymerized solid electrolyte system paired with a lithium-rich manganese cathode material.”
In late 2024, Chery announced the development of solid-state batteries, which were planned to achieve an energy density of 400 Wh/kg in the same year, rising to 600 Wh/kg by 2025, with the first test application in cars scheduled for 2026. Series production is then expected to begin in 2027. At the time, Chery announced that it would introduce a new battery subsidiary, Kunpeng Battery Brand. As mentioned above, this subsidiary is currently slated to launch pilot testing in 2026 and will not enter the commercial market until 2027 at the earliest. In the meantime, a supply deal was signed with LG Energy Solution for cylindrical battery cells.
Axxiva, a Chinese battery manufacturer backed by Chery and Gotion High-Tech, which is also known as Anhui Anwa New Energy Technology, has already begun production of its first solid-state battery prototypes. Axxiva’s prototypes managed to achieve an energy density of 300 Wh/kg when the batteries started rolling off the assembly line in July.
The development scene around solid-state batteries has been heating up lately, with Toyota expanding its development partnership with Sumitomo just a few days ago, while China’s Institute of Metal Research developed a new polymer for solid-state batteries shortly before that. SK On also opened a new pilot plant to fast-track the development of solid-state batteries, and Volkswagen is also closing the development gap with its own battery technology.
