Semi-Solid State Battery Adoption in EVs Gains Traction

Semi-Solid State Battery Adoption in EVs Gains Traction

TrendForce’s latest research reveals that semi-solid state batteries—blending features of traditional liquid electrolyte and solid-state batteries—entered trial production before 2020. However, due to high costs and technological limitations, adoption in electric vehicles (EVs) has lagged behind initial market expectations.

Looking ahead, TrendForce forecasts a gradual increase in the use of semi-solid state batteries by global automakers, with market penetration projected to exceed 1% by 2027.

China Leads in Early Adoption

Chinese automakers have been at the forefront of semi-solid state battery integration since 2022. Leading battery manufacturers such as Ganfeng Lithium, Farasis Energy, and WeLion New Energy have developed and scaled up production to the GWh level in recent years.

Despite these advancements, TrendForce data indicates that global usage of semi-solid state batteries in EVs remained below 2 GWh in 2024, with a market penetration rate of under 0.5%. Several Chinese EV models—IM L6, NIO ET7, Seres 5, DongFeng Aeolus E70, and Voyah Passion—feature semi-solid state batteries, though consumer adoption remains limited. Outside of China, no mass-produced EVs with this technology have been introduced yet, but broader global adoption is expected after 2025.

Advantages and Challenges

Compared to fully solid-state batteries, which face major production hurdles, semi-solid state batteries are closer to commercialization. By incorporating semi-solid electrolytes with a small proportion of liquid electrolytes, they achieve higher energy density, enabling longer EV driving ranges.

However, challenges remain. Semi-solid state batteries still fall short of traditional liquid electrolyte batteries in terms of cost, charge/discharge efficiency, and cycle life. Continued improvements in cost reduction and performance optimization will be key to achieving widespread adoption in the EV market.
