Electric vehicles (EVs) capable of driving over 1,000 miles on a single charge could hit roads by 2027, thanks to breakthroughs in solid-state battery technology. Leading automakers and battery giants are accelerating efforts to bring this game-changing innovation to mass production.
Industry Leaders Charge Ahead
Mercedes-Benz recently announced a milestone: its collaboration with Factorial Energy has successfully integrated lithium-metal anode solid-state batteries into a production car platform. The prototype EQS sedan achieved a 25% range boost, exceeding 1,000 kilometres, while enhancing safety by replacing flammable liquid electrolytes with solid alternatives.
In China, CATL and BYD are driving rapid progress. CATL aims to launch its second-generation solid-state battery (500 Wh/kg) by 2027, while BYD plans to debut semi-solid-state batteries in luxury models by 2025. Professor Ouyang Minggao, a top EV expert in China, predicts full solid-state batteries will enter the market by 2027, with mass adoption by 2030.
Why Solid-State Batteries Matter
Solid-state batteries promise three key advantages:
- Longer range: Energy densities up to 2x current lithium-ion batteries.
- Safer operation: No risk of leaks or fires from liquid electrolytes.
- Faster charging: Potential to recharge to 80% in under 15 minutes.
Major challenges remain, including high production costs and durability concerns. However, industry events like the 2025 Global Solid-State Battery Summit in China highlight growing momentum to solve these issues.
The Road Ahead
With Mercedes, CATL, and BYD leading the charge, the 1,000-mile EV era is closer than ever. As solid-state batteries shift from labs to production lines, drivers may soon say goodbye to range anxiety—and hello to a cleaner, electrified future.
