Battery structure editing

Lithium batteries usually have two types: cylindrical and square.The inside of the battery is a spiral wound structure, with a very fine and permeable polyethylene film separation material between positive and negative.The positive electrode consists of a current collector of lithium cobalt oxide (or nickel cobalt manganese acid, lithium manganate, lithium iron phosphate, etc.) and aluminum foil.The cathode is made up of a current collector consisting of graphitized carbon materials and copper foil.The battery is filled with an organic electrolyte solution.There are also safety valves and PTC components (partially cylindrical) to protect the battery from damage when the battery is in abnormal condition and the output is short-circuited.


Single section of lithium battery voltage of 3.7 V (3.2 V lithium iron phosphate anode), battery capacity is not likely to infinite, therefore, will be a single section often lithium battery series, in parallel processing, in order to meet the requirements of different occasions.
