TrendForce’s latest research reveals that semi-solid state batteries, a promising technology combining the best features of traditional liquid electrolyte batteries and solid-state batteries, have been in trial production since 2020. However, high production costs and the technology’s limited maturity have slowed their adoption in electric vehicles (EVs), falling short of initial expectations.

Despite these challenges, TrendForce forecasts steady growth in the use of semi-solid state batteries, predicting that they will achieve over 1% market penetration by 2027. Chinese automakers have been at the forefront of integrating semi-solid state batteries into their EV models, with major battery manufacturers like Ganfeng Lithium, Farasis Energy, and WeLion New Energy making significant strides in mass production at the GWh level.

In 2024, the global usage of semi-solid state batteries in EVs remained below 2 GWh, representing less than 0.5% of the market. Although several EV models equipped with this technology, such as the IM L6, NIO ET7, and Voyah Passion, have been launched in China, consumer acceptance has been limited so far. Additionally, no mass-produced EVs featuring semi-solid state batteries have been introduced outside of China, although TrendForce predicts a broader global rollout after 2025.

Semi-solid state batteries are considered closer to commercialization compared to all-solid-state batteries, which face significant technical hurdles for large-scale production. These batteries use a semi-solid electrolyte, supplemented by a small amount of liquid electrolyte, enabling higher energy density and longer driving ranges for EVs.

Despite their potential, semi-solid state batteries still face hurdles, including higher costs, lower charge/discharge efficiency, and shorter cycle life compared to traditional liquid electrolyte batteries. To achieve widespread adoption, further advancements in cost reduction and performance optimization will be essential.
