What is the structure of lithium ion battery?

　　The composition of lithium -ion batteries is composed of four parts: positive pole, negative electrode, non -hydrolytic, and diaphragm. Among them, positive and negative electrodes include active electrode substances, conductives, adhesives, etc., which are evenly applied to copper foil and aluminum foil collective fluids.

　　1. Positive active substances are generally lithium manganate or lithium cobaltate, nickel cobalt lithium manganate materials, and electric bicycles are generally used with nickel cobalt lithium manganate or a small amount of lithium lithium manganate, pure lithium manganate and lithium iron phosphate. It gradually fades due to large volume, poor performance or high cost. The conductive fluid uses electrolytic aluminum foil with a thickness of 10--20 microns.

　　2. A membrane is a high -molecular film with a special forming. The film has a microporous structure that allows lithium ions to pass freely, and electrons cannot pass.

　　3. The negative active substance is graphite, or the carbon that is similar to graphite structure. The conductive collecting fluid uses an electrolytic copper foil with a thickness of 7-15 microns.

　　4. The carbonate solvents with lithium hexarofluorophosphate are dissolved in the electrolyte, and the polymer uses a gel -like electrolyte.

　　5. The battery shell is divided into steel shells, aluminum shells, nickel -plated iron shells), aluminum plastic films, etc., as well as the battery block, which is also the positive and negative end of the battery.

　　The positive electrode potential of lithium -ion batteries is high, which is often a lithium -embedded metal oxide, or polycotic ionic compounds, such as lithium cobaltate, lithium manganate, ternary, lithium iron phosphate; Such as graphite and non -graphitic carbonized; lithium -ion battery electrolytes are important for non -hydraulic solutions, consisting of organic hybrid solvents and lithium salt. The solvents are mostly organic solvents such as carbonate. Lithium salt is mostly unit -priced polycinomic lithium salt, such as Lithium fluorophytic lithium; lithium -ion battery diaphragm is mostly polyethylene and polyalite microres, which can beolate positive and negative electrodes to prevent electrons from causing short circuits and at the same time to allow the use of ions in the electrolyte.
