On September 16th, it was reported that Farasis Energy, via an interactive platform, revealed that its third-generation semi-solid-state batteries utilize in-situ solidification technology. This technology involves integrating solid-state electrolytes into both the positive and negative electrodes, thereby reducing the electrolyte content. The company has set a target to commence mass production of these batteries by 2026. At present, when paired with high-energy-density positive and negative electrode materials, the energy density of the soft-pack battery cells has soared to 400Wh/kg. The decreased electrolyte usage and the incorporation of solid-state oxide electrolytes have significantly bolstered the safety profile of the battery cells. Moreover, the compatibility of these solid-state electrolytes with high-energy-density active materials paves the way for the development of highly secure all-solid-state batteries, boasting an energy density that surpasses 500Wh/kg.
