Introduction of structure of Large Capacity Lithium Battery, ES12250:
(1) Positive electrode data: transition metal oxide or polyanionic compounds with a layered or spinel structure with high lithium potential and stable structure, such as lithium cobaltate, lithium manganate, lithium iron phosphate, Ternary data, etc.
(2) Negative data: The potential is close to the lithium potential, the structure is stable, and many lithium-plated layered graphite, metal elements and metal oxides, such as graphite, central phase carbon microspheres, lithium titanate, etc.
(3) Electrolyte: an organic solvent in which an electrolyte lithium salt is dissolved, and supplies lithium ions. The electrolyte lithium salt includes LiPF6, LiClO4, LiBF4, etc., and the organic solvent mainly consists of diethyl carbonate (DEC), propylene carbonate (PC), and carbonic acid. One or a mixture of vinyl ester (EC), dimethyl ester (DMC), and the like is composed.
(4) Barrier: placed between the positive and negative electrodes, avoiding direct contact between the positive and negative electrodes, and allowing the polyene microporous membrane through which Li+ ions pass, such as polyethylene (PE), polypropylene (PP), or their composite membrane, PP/PE/PP three-layer barrier.
(5) Housing: battery package, mainly aluminum shell, cover plate, tabs, insulation sheets, etc.
