description Abstract The material Li1.5Al0.5Ti1.5(PO4)3 is a lithium fast ion conductor with three-dimensional ion channels. It exhibits high ionic conductivity, with lithium ion conductivity. To prevent long-term direct contact between Li1.2Mn0.54Ni0.13Co0.13O2 material and electrolyte, and avoid HF corrosion of the electrode produced by the decomposition of the electrolyte. A three-dimensional skeleton lithium fast ion conductor Li1.5Al0.5Ti1.5(PO4)3 coating layer was successfully synthesized on the surface of the lithium-rich manganese-based positive electrode material Li1.2Mn0.54Ni0.13Co0.13O2. The experimental results show that the Li1.2Mn0.54Ni0.13Co0.13O2@Li1.5Al0.5Ti1.5(PO4)3 composite material with a coating amount of 3% has the highest capacity retention rate after 100 cycles. The capacity retention rate reaches 85.9% after 100 cycles at 0.1 C, which is better than the 82.14% of the base material. It proves that the Li1.5Al0.5Ti1.5(PO4)3 coating layer effectively prevents the occurrence of side reactions during long cycles, stabilizes the electrode surface structure, and reduces capacity loss.
