What is cylindrical batteries?
The cylindrical lithium batteries include lithium iron phosphate, lithium cobalt, lithium manganese, mixed cobalt manganese, and ternary material systems. The shell is divided into a steel shell and a polymer shell, which have different advantages. At present, the cylindrical batteries are mainly made of steel-shell cylindrical lithium iron phosphate materials. This kind of battery has high capacity, high output voltage, good charge and discharge cycle performance, stable output voltage, large current discharge, safe to use, wide operating temperature range, and environmentally friendly, it is widely used in solar lamps, lawn lamps, back-up energy, power tools and toy models.
The structure of cylindrical lithium ion batteries
The structure of a typical cylindrical battery includes: shell, cap, positive electrode, negative electrode, separator, electrolyte, PTC element, gasket, safety valve, etc. Generally, the battery casing is the negative electrode of the battery, the cap is the positive electrode of the battery, and the battery casing is made of nickel-plated steel.
