The negative electrode material is the main body of lithium ion battery to store lithium, so that lithium ions are inserted and extracted during the charging and discharging process.
Numerous electrode materials have been developed since the first commercial lithium-ion battery introduced in 1990 [1], [2]. Commercial lithium-ion batteries often employ layered LiCoO 2 as the cathode material and graphitized carbon as the anode material because of high working voltage and cell stability [3].
Tokai Carbon produces anode materials for secondary lithium-ion batteries and supplies them to battery manufacturers. Secondary lithium-ion batteries are used in, for example, smartphones and electric cars. This new division has a lot of growth potential. What are Anode Materials? Lithium-ion batteries are rechargeable.
In a lithium-ion battery, the anode is the “negative” or “reducing” electrode that provides a source of electrons. Classically, anode materials are made of graphite, carbon-based materials, or metal oxides, which are called intercalation-type anodes.
In a lithium-ion battery, the cathode is the electrode that acquires electrons from the external circuit and plays a critical role in maintaining charge balance by simultaneously intercalating lithium ions. Typically, the cathode consists of a cathode active material (CAM, ~90%), polymeric binder (~5%), and a conductive additive (~5%).
Lithium ions can move back and forth between the positive and negative electrodes. This means they can move away from the graphite anode to the positive electrode during discharge and can then move back to it during charging. This mechanism works because of graphite's structure and chemical stability.
