3.Graphene-based Material 

-Graphene is a two-dimensional carbon nanomaterial composed of a carbon atom and a sp2 hybrid  orbital to form a hexagonal honeycomb lattice. 

-Graphene has excellent optical, electrical and mechanical properties in materials science, micro-nano  processing, energy, biomedicine. It has important application prospects in terms of drug delivery and  is considered to be a revolutionary material in the future. 

-As a positive electrode material for lithium batteries, graphene effectively increases the capacity of the  battery, reduces its own power consumption, and improves the battery cycle life.
