Chery's 1500 km Solid-State Battery Breakthrough

The source outlines the details of a new solid-state battery developed by the automotive company Chery, which was unveiled at their Global Innovation Conference in 2025. This prototype battery boasts an extremely high energy density of 600 Wh/kg, which could translate to an electric vehicle range exceeding 1,500 kilometers on a single charge. Developed by an internal team, the battery uses a polymerized solid electrolyte with a manganese and high-lithium cathode, enabling it to maintain performance even in extreme conditions and pass stringent safety tests. Chery expects to begin commercial applications of this technology as early as 2027, potentially giving them a significant advantage over competitors who anticipate later release dates.
