In the pursuit to increase energy density of lithium-ion batteries (LIBs), considerable efforts have focused on developing high-capacity cathode materials. While Ni-rich (Ni ≥ 80 at. %) layered materials are considered a viable commercial option, surface engineering is crucial for enhancing their cycle performance successful implementation in LIBs. Various functional been explored effective protection and stabilization reduce interfacial resistance enhance structural stability this context, we propose coating with nonstoichiometric lithium hexagonal tungsten bronze (LixWO3) via simple wet-coating. We demonstrate that distinctive physicochemical properties LixWO3, such as its high ionic conductivity (∼10-6 S cm-1) mechanical strength (∼236.0 MPa), beneficial by modulating reactions without undesirable loss reversible capacity. practice, LixWO3 layer induces significant reduction strain relaxation upon repeated Li+ insertion extraction. Our findings provide insights into development highly reliable high-energy
