Graphite Anode Material for Li-Ion Batteries
graphite anode material is one of the most important components of a lithium-ion battery. It meets the voltage requirements of most Li-ion cathodes, is extremely light and porous, and can be produced at a very low cost.
Currently, the anode materials used for Li-ion batteries are artificially or naturally produced graphite powders that are pressed onto a copper foil. Usually, this is done by using binder and conductive additives to force the lithium atoms to find a fixed position in the lattice structure of the powder.
There are many alternative anode materials, but graphite is still the preferred choice because it offers numerous benefits: high coulombic efficiency, long cycle life, and a wide range of potential applications.
A growing number of research projects are focusing on alternative anode materials that can offer increased energy density and a safer charging process. Some approaches are focused on improving the graphite surface through ex situ surface modification, while others use electrolyte additives to further improve the first cycle coulombic efficiency of a conventional anode material.
As a result, graphite is a key material for the future of the anode industry, as it can be tailored to provide improved performance and safety without compromising cost efficiency. Superior Graphite has modified its well-established fluidised bed technology to apply it to the production of natural flake and synthetic graphite-based anode materials for the fast-growing Li-ion battery market.
