Chery is making significant advancements in the field of solid-state batteries, targeting an impressive energy density of up to 600 Wh/kg for its future EVs. Large-scale production of these innovative battery cells is expected to begin in 2027, following the completion of their development.
While solid-state batteries are widely seen as the next major breakthrough for electric vehicles, Chery isn’t the only player in the game. Both startups and established car manufacturers are working on similar technologies. During the recent Chery Global Innovation Conference, the automaker confirmed that their work on solid-state batteries is progressing well, with prototypes currently offering an energy density of 400 Wh/kg. This will be further enhanced to 600 Wh/kg by 2025. Chery aims to install these batteries in its cars by 2026, followed by large-scale production the year after. These batteries could offer up to 1,500 km (932 miles) of range on a single charge, a potential game changer for EVs.
Though many companies are developing solid-state batteries, no electric vehicle has yet launched with one. However, 2023 saw the debut of the Nio ET7 and IM L6, which are equipped with semi-solid-state batteries, marking the industry’s gradual shift toward this technology.
Chery also announced other important battery developments during the conference. The company has created new types of batteries, including square lithium-iron phosphate, square ternary, and large cylindrical ternary cells. These advanced batteries can add an impressive 400 km (249 miles) of driving range with just 5 minutes of charging.
The square lithium-iron phosphate batteries are designed for EVs with a range of 200–600 km (124–372 miles), as well as for PHEVs and EREVs with an electric range of 100–200 km (62–124 miles). Meanwhile, Chery’s square ternary batteries will power EVs with ranges of 600–800 km (373–497 miles) and PHEVs/EREVs with 150–300 km (93–186 miles) of electric range. Lastly, the cylindrical cells are developed for EVs offering a range of 700–1,200 km (435–746 miles) and PHEVs/EREVs with ranges between 150–300 km (93–186 miles).
