Abstract
Strategies to optimize the cathode/solid electrolyte interphase (CSEI) have been developed to improve the high voltage durability of LiCoO2 (LCO), yet the underlying interfacial mechanism remains unclear. Here, we construct a stable oxyhalide-derived CSEI for all-solid-state batteries (ASSBs) to identify the key interfacial features required for high-voltage operation. At 4.6 volts, commercial LCO coupled with Li6PS5Cl (LPSC) suffers from severe interfacial instability, sluggish Li+ transport, and continuous side reactions. By introducing LiNbOCl4 (LNOC), an in situ formed CSEI rich in Li-Cl/Nb-O/Nb-O-Cl species is established, lowering the interfacial energy barrier to 0.363 electron volts and enhancing interfacial toughness and ionic conductivity. This stabilized interface suppresses lattice oxygen activity, accelerates Li+ transport, and improves the reversibility of O3/H1-3 phase transitions. Consequently, LCO|LNOC|LPSC|Li-In ASSBs deliver 95.8% capacity retention after 500 cycles at ∼1.0 C-rate with an LCO loading of 15.31 milligrams per square centimeter. The pouch cell achieves 90% initial Coulombic efficiency and stable cycling over 50 cycles.
The lithium argyrodite-type electrolyte exhibits excellent ion transport properties for all-solid-state batteries (ASSBs). However, their practical implementation is limited by poor cycle stability, arising from the coupled chemo-mechanical degradation. To address these issues, we developed an effective interfacial eng...

Lithium cobalt oxide (LiCoO2, LCO) is one of the most successful cathodes. However, it suffers from severe structural degradation and rapid capacity fading at high voltage (>4.5 V vs. Li+/Li). To improve high-voltage stability, researchers employ channel-type materials to desolvate lithium ions, resulting in a localize...

The solid-electrolyte interphase in liquid-electrolyte systems reaches a self-passivating steady state by electrolyte design. However, the interphase in all-solid-state batteries (ASSBs) arises from mutual electrochemical decomposition between the anode and solid electrolyte, yielding unpredictable composition, poor io...

High-voltage all-solid-state batteries (ASSBs) promise high-energy-density storage, but oxidative instability of solid-state electrolytes at cathode interfaces remains a major obstacle. Here, we report a sacrificial-additive strategy for durable, high-voltage operation of low-cost Zr-based halide ASSBs. Introducing LiP...
