Back Up Power Supply LifePo4 12.8V 10Ah Energy Battery Pack

1. Definition of cylindrical battery

Cylindrical lithium batteries are divided into lithium iron phosphate, lithium cobalt oxide, lithium manganese oxide, cobalt-manganese hybrid, ternary material different systems, shells are divided into steel shell and polymer, different material system batteries have different advantages. At present, the cylinder is mainly based on steel-shell cylindrical lithium iron phosphate batteries, which are characterized by high capacity, high output voltage, good charge-discharge cycle performance, stable output voltage, high-current discharge, stable electrochemical performance, safe use, wide operating temperature range, and environmental friendliness, and are widely used in solar lamps, lawn lamps, backup energy, power tools, and toy models.

2. Cylindrical battery structure

The structure of a typical cylindrical battery includes: housing, cap, positive electrode, negative electrode, separator, electrolyte, PTC element, gasket, safety valve, etc. Generally, the battery shell is the negative electrode of the battery, the cap is the positive electrode of the battery, and the battery shell is made of nickel-plated steel plate.
