Poly(ethylene oxide) (PEO)-based electrolytes are the most commonly used in commercial Li-metal based solid-state batteries (SSBs). However, its use with high-voltage positive electrodes remains a challenge due to the limited electrochemical stability of PEO.
Researchers at CIC energiGUNE have developed a solid-state battery including two different polymer electrolytes, one as solid polymer electrolyte (SPE), and the other as solid polymer catholyte (SPC; electrolyte within the cathode). The SPE is a polymer compatible with Li-metal, while the SPC is suitable for high-voltage active materials. The combination of both polymers on the same device is only feasible using a single-ion conducting salt.
