Performance of Lithium Ion Battery with Graphene Microstructure in Cathode

Lithium-ion battery is a promising energy source with high output voltage, large energy density, low auto discharge, and no memory effect. Graphene, as a dimensional carbon material, has excellent electrical conductivity, strong mechanical properties, a large specific surface area, which has been widely applied in lithium-ion battery for modifying the cathode material of lithium secondary batteries, thus significantly promoting the flow performance, conductivity, and cycling stability of Li secondary batteries. In this review, we discussed the excellent properties of various cathode materials based on graphene with different microstructures including three dimensional network structure, Core/Shell structure, layered structure, porous structure, and sandwich structure, which could provide motivations for improving the performance of the lithium-ion battery.
