Graphite Applications in The New Energy Industry

Graphite has a wide range of applications in the new energy industry, mainly including:
1. Lithium battery anode material: Graphite is one of the most commonly used anode materials for lithium-ion batteries. It has the advantages of high volume density, large capacity, and long cycle life. Graphite is usually mixed with lithium compounds such as LiC6 to make graphite negative electrode materials.
2. Supercapacitor electrode: Supercapacitors use high surface area activated carbon or graphite as the electrode material. Graphite is often used as the negative electrode of supercapacitors due to its high volume density, large porosity, and good electrochemical properties.
3. Solar cell copper indium gallium selenide (CIGS) absorption layer: CIGS solar cells are a new generation of thin film solar cells. One of the main materials of the light absorption layer is graphite, which is used to improve the conductivity of the absorption layer.
4. Fuel cell catalyst carrier: In fuel cells such as proton exchange membrane fuel cell stacks (PEMFC), catalysts are needed to accelerate the hydrogen-oxygen reaction, and one of the functions of graphite is to serve as a carrier for these catalysts.
5. Lithium-sulfur battery cathode materials: In recent years, lithium-sulfur batteries have received widespread attention as a new high-specific energy battery. Currently, graphite has also been proven to be one of the promising cathode materials for lithium-sulfur batteries. In addition, graphite is also used in brake pads and friction pads of new energy vehicles, photovoltaic brackets, etc., showing great potential in the new energy industry.
