SAIC advances EV development with semi-solid-state batteries

Chinese automotive giant SAIC has announced it's moving to a new phase in electric vehicle development, with various brands under its umbrella set to begin mass-producing models featuring semi-solid-state batteries as early as 2026. This could mark a significant step in automotive evolution and boost interest in electric cars.

The first example is a new version of the MG4 with a semi-solid-state battery, which has already reached customers. The MG 4X crossover with the same technology is also in the pipeline. This signals the innovation's transition from testing into real-world, mass-market application.

Simultaneously, SAIC is actively developing full solid-state batteries. A production line is already operational in Shanghai, with the first prototypes expected in 2026. Widespread adoption is anticipated by 2027, when a next-generation battery boasting an energy density exceeding 400 Wh/kg is set to debut.

The key advantage of these solutions is safety. Even when punctured or heated to 200 degrees Celsius, the cells do not ignite or explode. Furthermore, they maintain high efficiency in low temperatures, a critical factor for practical use. The company has set ambitious goals: to sell up to 5 million vehicles annually and increase revenue to 700 billion yuan. The introduction of these new batteries is positioned as a key growth driver.

If SAIC can successfully scale up semi-solid-state battery production, it would gain a serious competitive edge. Once again, Chinese brands are setting the pace, leaving traditional automakers at risk of playing catch-up.
