A semi-solid-state battery (also formally known as a quasi-solid-state battery, QSSB) is a type of rechargeable battery that serves as an intermediate technology between conventional lithium-ion batteries (LIB) with liquid electrolytes and all-solid-state batteries (ASSB) using a hybrid solid-liquid semi-solid-state electrolyte.

The primary goal of this technology is to improve battery safety by reducing the amount of flammable liquid electrolyte, thereby mitigating the risk of fire and dendrite growth associated with traditional LIBs. At the same time, it aims to overcome the significant challenges facing the ASSBs, such as high interfacial resistance and poor contact between the solid electrolyte and the electrodes. As of 2023, commercially available batteries marketed as "solid-state" were in fact quasi-solid-state batteries.
