“…The commercially available solid electrolyte Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 exhibits superior ionic conductivity to that of conventional oxides. 17 This approach can increase the Li + transfer rate when used for surface modification. Additionally, certain ions can diffuse into the material lattice during high-temperature calcination.…”

In this study, the heterostructure cathode material LiCoO 2 @Co 3 O 4 @Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 was prepared by coating Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 on the surface of LiCoO 2 through a one-step solid-phase synthesis. The morphology, structure, electrical state, and elemental contents of both pristine and modified materials were assessed through a range of characterization techniques. Theoretical calculations revealed that the LCO@LLZTO material possessed a reduced diffusion barrier compared to LiCoO 2 , thereby facilitating the movement of Li ions. Electrochemical tests indicated that the capacity retention rate of the modified cathode composites stood at 70.43% following 300 cycles at a 2C rate. This high rate occurred because the Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 film on the surface enhanced the migration of Li + , and the spinel phase of Co 3 O 4 had better interfacial stability to alleviate the generation of microcracks by inhibiting the phase change from the layered phase to the rock-salt phase, which considerably improved the electrochemical properties.
