A severely crushed automotive battery deformed by half still runs stably. Placed in a high-temperature oven at 170°C, it produces no smoke and triggers no fire. These extreme torture tests are not fictional laboratory results, but real, verified experiments conducted by Dongfeng on its self-developed solid-state batteries.
For most EV users, the biggest concern is never short driving range, but the hidden safety risk of sudden battery thermal runaway. Traditional liquid lithium batteries rely on passive protection designs, while Dongfeng’s new solid-state battery solves core safety problems from the source. It replaces flammable liquid electrolytes with high-stability solid structures, achieving reliable structural safety rather than relying on passive risk avoidance.
Scheduled for mass production and vehicle installation in the second half of 2026, Dongfeng’s solid-state battery boasts an ultra-high energy density of 350Wh/kg, a practical and industry-leading core parameter. Equipped on new energy models, it enables a pure electric cruising range exceeding 1,000km, completely eliminating mainstream users’ range anxiety in daily commutes and long-distance travel.
Currently, the global solid-state battery industry has three mainstream technical routes: polymer, sulfide, and oxide. Dongfeng adopts the mature oxide-polymer composite route, which features mature raw material production, lower manufacturing costs, and excellent compatibility with existing automobile production lines. This allows rapid large-scale market promotion, far ahead of high-cost, difficult-to-commercialize sulfide solid-state solutions.
Dongfeng’s mass-produced solid-state battery realizes a perfect dual breakthrough of extreme safety and ultra-long battery life, marking a key milestone in the localized upgrading of China’s new energy vehicle core technologies.
