High-voltage stability of sulfide-based all-solid-state batteries: benefit of the parasitic reaction
Severe interfacial degradation occurs in sulfide-based all-solid-state batteries (ASSBs) at high voltages, due to the parasitic reaction between the solid electrolyte (SE) and Ni-rich layered oxide. Herein, we show that a conformal nanoscale coating of Li<sub>6</sub>PS<sub>5</sub>Cl (LPSCl) on LiNi<sub>0.8</sub>Co<sub>0.1</sub>Mn<sub>0.1</sub>O<sub>2</sub> (NCM) promotes the homogeneous parasitic reaction and improves the high-voltage stability, enabling durable cell operation, even after extended storage at 4.25 V <i>vs.</i> Li/Li<sup>+</sup>.
