Li Ion Graphite As an Anode for Li-Ion Batteries
li ion graphite is a perfect anode material for lithium-ion batteries (LIBs). Its incomparable balance of low cost, abundant supply, high energy density and long cycle life have made it the most popular anode material in the world.
Graphite is a natural form of carbon. It is a soft, malleable and heat-resistant substance that has excellent electrical and thermal conductivity as well as chemically passive properties. It is used in many industries including fuel cells, solar cells, semiconductors and nuclear reactors.
The EV battery market is expected to grow rapidly over the next few years, requiring at least 172,000 tonnes of graphite annually for producing the anodes. Even modest EV adoption rates will require flake graphite production to double by 2025, as noted in a Benchmark Mineral Intelligence report.
Synthetic li ion graphite is an emerging alternative to conventional natural graphite. It can be produced through hydrothermal and electrochemical processes from a wide range of waste streams. Several companies are manufacturing synthetic graphite for use as an anode material in lithium-ion batteries.
Structure of GLG, a novel graphene-based anode for lithium-ion batteries: 1. Conclusion: A large increase in the interlayer space (0.341 to 0.483 nm) was observed in fully charged GLG (Fig. 12) which is attributed to the migration of O atoms to the interlayer space through one of the C-O bonds. Moreover, the presence of O atoms pairwisely introduced within the graphene sheets and nanopores 1-5 nm in length were also detected. These features contribute to the high capacity of GLG, which is greater than the theoretical capacity of pristine graphite.
