Dual-interfacial engineering via LiPF 6 treatment: eradicating Li 2 CO 3 on LLZTO and regulating SEI for high-voltage solid-state batteries
Abstract
transference number of 0.750, and enabled stable cycling for over 1000 h in a Li symmetric cell with suppressed lithium dendrite growth. When paired with an NCM811 cathode, the solid-state battery delivered a capacity retention of 88.6% after 100 cycles at 0.5 C (2.7-4.3 V) and maintained 80.3% retention at a high voltage of 4.5 V. This efficient and economical interfacial optimization strategy, which synchronously improved filler-polymer compatibility and regulated SEI layer properties, provided a general and practical solution for interface engineering in the fabrication of high-performance PVDF-based CPEs and ASSLBs.
