Phone batteries online manufacture: five structures that make up the phone battery
Nowadays, lithium batteries have become the mainstream of mobile phone batteries. Many phone batteries online manufacturers mainly sell lithium batteries. So what are the structures of the batteries produced by these phone batteries online manufacturers? In general, phone batteries online manufacturers divide the battery into five parts: anode material, cathode material, diaphragm, and electrolyte casing. 1. Anode material: layered graphite with a potential close to the lithium potential, stable structure and capable of storing a large amount of lithium, a simple metal and a metal oxide such as graphite, mesophase carbon microspheres, lithium titanate, and the like. 2. Cathode material: a transition metal oxide or polyanionic compound having a high electrode potential and a stable lithium-plated layer or spinel structure, such as lithium cobaltate, lithium manganate, lithium iron phosphate, and the like. Metamaterials, etc. 3. Diaphragm: a polyene microporous film that is placed between the positive and negative electrodes to prevent direct contact between the positive and negative electrodes and allows ions of Li + to pass, such as polyethylene (PE), polypropylene (PP), or a composite film thereof. , PP / PE / PP three-layer diaphragm. 4. Electrolyte: an organic solvent in which an electrolyte lithium salt is dissolved to provide lithium ions, an electrolyte lithium salt having LiPF 6, lithium perchlorate, LiBF 4, etc., and an organic solvent mainly composed of diethyl carbonate (DEC), propylene carbonate. One or a mixture of ester (PC), ethylene carbonate (EC), dimethyl ester (DMC), and the like. 5, the outer casing: battery package, mainly aluminum shell, cover plate, tabs, insulation sheets, etc.
The above is the division of the lithium battery structure by phone batteries online manufacturers.
