Steel shell/aluminum shell/cylindrical/flexible packaging series:

　　(1) Positive electrode - the active substance is generally lithium manganese oxide or lithium cobalt oxide, nickel cobalt manganese oxide lithium material, electric self-propelled

　　Cars generally use nickel cobalt lithium manganese oxide (commonly known as ternary) or ternary+a small amount of lithium manganese oxide, pure lithium manganese oxide and phosphoric acid

　　Lithium iron gradually fades out due to its large volume, poor performance, or high cost. Conductive current collector with a thickness of 10-20

　　Micron electrolytic aluminum foil.

　　(2) Diaphragm - a specially formed polymer film with a microporous structure that allows lithium ions to form

　　Free passage, but electrons cannot pass through.

　　(3) Negative electrode - the active material is graphite, or carbon with a similar graphite structure, and the conductive current collector uses a thickness of 7-15

　　Micron electrolytic copper foil.

　　(4) Organic electrolyte - carbonate solvent dissolved with lithium hexafluorophosphate, and gel is used for polymer

　　Liquid electrolyte.

　　(5) Battery shell - divided into steel shell (rarely used in square shape), aluminum shell, nickel plated iron shell (used in cylindrical batteries), aluminum-plastic film (soft packaging), etc., as well as the battery cover, which is also the positive and negative terminals of the battery.

　　work efficiency

　　Lithium ion batteries have a high energy density and an average output voltage. Low self discharge, good batteries with a monthly rate of over 2%

　　Down (recoverable). There is no memory effect. The working temperature range is wide from -20 ℃ to 60 ℃. Superior cycle performance

　　It can quickly charge and discharge, with a charging efficiency of up to 100%, and a large output power. Long service life. Not containing toxic substances

　　Harmful substances, known as green batteries.
