Comparison between graphene battery and lithium battery

　　1. Graphene battery: Graphene battery is a honeycomb flat facial mask formed by the SP2 hybridization of carbon atoms. It is a quasi two-dimensional material with only one atomic layer thickness, so it is also called monoatomic layer graphite. A new energy battery was developed by using the rapid and wide range shuttle motion of lithium ions between graphene surface and electrode. Graphene has the characteristics of high conductivity, high strength, ultra-thin and so on, and has outstanding application advantages in the aerospace field. Graphene is called the "king of new materials" by researchers and major media. It is a new nano material with high strength, good toughness, light weight, high transmittance and good conductivity.

　　2. Lithium battery: "Lithium battery". The lithium ion in the lithium ion battery refers to the energy storage material in the battery. Battery reactions (chemical changes) occur during charging and discharging. It is a battery with lithium metal or lithium alloy as cathode material and non-aqueous electrolyte solution. Lithium batteries can be roughly divided into two categories: metal lithium batteries and lithium ion batteries. Lithium ion batteries do not contain lithium metal and can be recharged. Lithium metal battery is the fifth generation rechargeable battery, which was born in 1996.

　　The huge defects of lithium battery in safety, durability, environmental pollution and charging speed have seriously restricted the development of major high-tech industries. Therefore, many R&D departments of enterprises focus on more advanced graphene batteries, and believe that this new battery will completely replace the lithium battery that has been more than 26 years in the future.
