What are the structural components of lithium batteries?

Lithium battery structure and composition From the lithium battery structure, it is mainly divided into the following five parts: 1. Positive electrode material: a layered or spinel structure transition metal oxide with a high electrode potential and a stable structure with the ability to intercalate lithium Or polyanionic compounds, such as lithium cobaltate, lithium manganate, lithium iron phosphate, ternary materials, etc. 2. Negative electrode material: The potential is close to the lithium potential, the structure is stable, and many lithium-storing layered graphite, metal element and metal oxides, such as graphite, central phase carbon microspheres, lithium titanate, etc. 3. Electrolyte: an organic solvent in which electrolyte lithium salt is dissolved to supply lithium ions. The electrolyte lithium salt includes LiPF6, LiClO4, LiBF4, etc. The organic solvent is mainly diethyl carbonate (DEC), propylene carbonate (PC), and ethylene carbonate Ester (EC), dimethyl ester (DMC) and a mixture of one or more of them. 4. Barrier: placed between the positive and negative electrodes to prevent direct contact between the positive and negative electrodes, and allow Li+ ions to pass through the polyene microporous membrane, such as polyethylene (PE), polypropylene (PP), or their composite membrane, PP /PE/PP three-layer barrier. 5. Shell: battery encapsulation, including aluminum shell, cover plate, tabs, insulating sheet, etc. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
