When batteries discharge, the anode active materials in the anode store the lithium ions delivered from the cathode and release them to produce energy. Graphite is the most widely used ingredient for anode active materials since it offers stability when lithium ions travel (charging and discharging).
Anode materials in Li-ion batteries encompass a range of nickel-based materials, including oxides, hydroxides, sulfides, carbonates, and oxalates. These materials have been applied to enhance the electrochemical performance of the batteries, primarily owing to their distinctive morphological characteristics .
First, the necessary cathode and anode materials will be synthesized into the desired compounds to create the electrode. This mixture of compounds is referred to as cathode active materials (CAM) and anode active materials (AAM), respectively.
The primary goal, from a practical perspective, is to prevent anode failure, which is essential for extending the battery's cycle life. Consequently, innovative and stable structures and materials have been created to enhance anode materials' ability to resist volume changes.
The active material in the cathode is called the “cathode active material,” and the active material in the anode is called the “anode active material.” The cathode active materials in the cathode hold lithium ions and send them to the anode as a battery charge. Cathode active materials are responsible for battery capacity and output.
Anode Active Materials The most common active material in conventional anodes is graphite. Graphite has been used for decades in lithium-ion batteries and its properties are very well understood. However, graphite pales in comparison to the theoretical capacity of alternatives such as silicon or lithium metal.
