Carbon Materials and Their Modified Materials for Lithium Ion Battery
Anodes : A Comprehensive Review
Abstract
As a negative electrode material for lithium ion batteries (LIBs),
carbon has a higher cycle life and higher safety. However, it has poor
electrical conductivity, low charging and discharging platform, and poor
stability of layered structure. Some carbon materials are complicated to
make such as synthetic graphene, and the shape is difficult to control.
Metal materials have good electrical conductivity, but due to the rapid
volume expansion of lithium ions during the cycle of insertion and
extraction, the electrodes are extremely quickly crushed and accompanied
by extremely rapid capacity decay. Scholars have combined the advantages
of carbon and metal materials to create a new type of carbon-based
composite material. This article outlines the use of carbon based
composite materials as lithium-ion electrodes to improve battery
performance.
