The three shapes of lithium batteries will eventually become cylindrical batteries, prismatic batteries and lithium polymer batteries through cylindrical winding, prismatic winding, and prismatic lamination. Different packaging structures mean different characteristics, so what are their differences? Part 1. What’s the cylindrical lithium battery?
The cylindrical lithium-ion battery boasts mature production technology with high yields. Models like 14650, 17490, 18650, 21700, and 26500 are among the many cylindrical battery types available. This type's production process is mature, resulting in lower PACK costs, higher battery product yield, and consistent PACK quality.
Cylindrical batteries are divided into lithium iron phosphate, cobalt oxide, manganate, cobalt oxide, and ternary systems. The shell is divided into two types: steel shell and polymer. Batteries with different material systems have different advantages. At present, cylindrical batteries are mainly steel-cased cylindrical lithium iron phosphate.
Lithium polymer batteries are currently the least used battery form in electric vehicles. But in fact, we are not unfamiliar with it. Most of the batteries in mobile phones are lithium polymer batteries. The biggest difference between lithium polymer, cylindrical, and prismatic batteries is that their outer casing is made of aluminum-plastic film.
