JAKARTA Dongfeng Automobile also enlivened the development of solid-state batteries. They have just announced a solid-state battery energy density of up to 350 liters/kg. Where, this battery is claimed to be able to provide a distance of more than 1,000 kilometers.

The technology is scheduled to be ready to be produced in September 2026, as reported by Carnewschina, Friday, November 14. According to the company's statement, this battery carries a multi-component structure that combines high-capacity ternary cathodes, silicon-carbon anodes, and solid electrolyte based on polymer oxides.

The combination allows stable performance in a variety of conditions, including extreme temperatures. At a temperature of minus 30 degrees Celsius, the battery is capable of retaining more than 72 percent of the energy, which is higher than conventional liquid batteries.

The battery also passed a thermal room security test at 170 degrees Celsius, exceeding the 130 degrees Celsius national standard. Dongfeng also introduced the latest electric vehicle platform specifically designed to support this battery.

The platform, named Mach Super-kV Pure-Electric, adopts a high voltage architecture of 1200 volts, a silicon-carbon power module of 1,700 volts, and a fast charging composite cell of twelve C. With support for chargers of up to 2 megawatts.

The charging is expected to increase the distance from about 2.5 kilometers per second and reach 450 kilometers in just 5 minutes of charging. From the safety aspect, Dongfeng stated that these solid-state batteries had gone through thermal space tests, surpassing China's national standards.

The platform is also designed to support 30,000 rpm speed motors, 48 hours of heat escape monitoring, and protection of battery collisions of up to 1,500 joules.

In addition, Dongfeng is preparing a faster charging-capable solid-state battery variant which is targeted to be integrated into vehicles by the end of 2027. The company is also starting to research sulfide-based solid-state batteries with an energy density that is increased to 500hubs/kg.
