What are Anode Materials?Lithium-ion batteries are rechargeable. They are used in things like mobile phones, computers, hybrid and electric cars. The cathode is made from lithium oxide, and the anode is made from carbon. Tokai Carbon produces and sells materials for the anode. Uniform quality and low cost are essential, particularly for anode materials used in large scale lithium-ion batteries like those in electric cars. At Tokai Carbon, we apply our excellent graphite production technology developed over our hundred-year history and use competitively priced raw materials to support the future of lithium-ion batteries.How Lithium-Ion Batteries WorkUnlike zinc-carbon batteries, lithium-ion batteries are rechargeable. Lithium ions can move back and forth between the cathode and anode. This means they can move away from the graphite anode to the cathode during discharge and can then move back to it during charging. This mechanism works because of graphite's structure and chemical stability. Lithium-ion batteries have a bigger battery capacity and operating voltage compared to other types of rechargeable battery and can withstand "top up" charging (charging before the battery is fully discharged). This makes them very powerful for their size and weight. Lithium-ion batteries are now gathering attention as batteries for electric cars.Anode Materials Division Basic informationAnode materialsSeparatorAnodeCathodeAnode Terminal (−) Cathode Terminal (+) ElectrolyteSeparatorWe produce the high quality and safe materials our customers demand by combining multiple raw materials and processing them in the optimal way.Main Raw MaterialsManufacturing ProcessProduction/development base: Production Technology Center (Hofu, Yamaguchi Prefecture)We supply anode materials to major battery manufacturers through Mitsubishi Chemical Corporation.SalesThe Lithium Ion Battery will be supplied to western electric vehicle makers through the battery producers.CustomersNatural graphiteCokesComposition(component adjustment)Heat treatmentGraphitizing(around 2 weeks)Finished product - Shipping61TOKAI CARBON ANNUAL REPORT 2018Vision and StrategyBusiness ReportSustainability ReportFinancial ReportData Section
