Graphene Oxide is a two-dimensional planar nanomaterial composed of carbon atoms with a hexagonal honeycomb lattice，the c-c bond length is 0.141nm, the theoretical density is about 0.77mg/m2, and the thickness is only about the diameter of a carbon atom. Carbon atoms participate in hybridization in the way of sp2, and electrons can smoothly conduct between layers, so graphene conducts electricity ...

For lithium ion batteries, the cathode materials that can be used should meet the characteristics of large reversible capacity, high potential and stability, non-toxic and low production cost. At present, lithium iron phosphate is the most common cathode material for lithium ion batteries. However, LiFePO4 has poor electrical conductivity and low lithium ion mobility. If LiFePO4 material is combin...
