Enhanced high-voltage cycling stability of LiNi0.5Co0.2Mn0.3O2 based on stable Li+-conductive ceramic Li6.5La3Zr1.5Ta0.5O12 nano cladding layer

Enhancing the cycling stability of conventional LiNixCoyMn1-x-yO2 cathode materials under high cut-off voltage (>4.3 V) is an efficient route for the fabrication of ternary layered lithium-ion batteries (LIBs) with superior capacity. A garnet ceramic Li6.5La3Zr1.5Ta0.5O12 (LLZTO) is used as a fun...
