- SK On plans to commercialize all-solid-state EV batteries by 2029, a year ahead of schedule.
- The new pilot plant in South Korea will focus on developing all-solid-state batteries with an energy density of 800 Wh/L initially, aiming for 1,000 Wh/L in the future.
- SK On's unique 'Warm Isostatic Press (WIP)-free' process improves battery density and performance without the need for a cell-sealing process.
- The company has improved bonding between electrodes and solid electrolytes, leading to smoother ion transport and longer battery life.
- Several major automakers and battery manufacturers, including Mercedes-Benz, BMW, and CATL, are also developing solid-state battery technology.
- Mercedes-Benz recently demonstrated a modified EQS with solid-state batteries achieving 1,205 km on a single charge.
- SAIC MG claims the MG4 is the world’s first mass-produced semi-solid-state EV, priced at 99,800 yuan in China.
