Graphite or silicon-based, lithium-ion battery anode material prospects

By

After years of development, the energy density of lithium-ion batteries has been greatly improved. Statistics show that the energy density of lithium-ion batteries increased three times from 1991 to 2015, with a GAGR (annual compound growth rate) of about 3%. However, from the perspective of actual technological development, the current growth rate of lithium-ion battery

Recycling and reuse of graphite negative electrodes in lithium-ion batteries

By

Graphite has become the mainstream lithium battery negative electrode material in the market due to its advantages such as high electronic conductivity, large lithium ion diffusion coefficient, small volume change before and after layered structure, high lithium insertion capacity and low lithium insertion potential. As the demand for lithium-ion batteries continues to grow, a large
