Advantages and disadvantages of square and cylindrical iron lithium ion batteries
●Cylindrical iron lithium ion battery
Advantages: Cylindrical iron lithium-ion battery is the earliest mature industrialized lithium-ion battery product. After more than 20 years of development, the production process of cylindrical lithium-ion battery is mature, the production efficiency is high, and the cost is relatively low, so PACK The cost of lithium-ion batteries is relatively low, and the yield of lithium-ion batteries is higher than that of square lithium-ion batteries and soft-pack lithium-ion batteries, and its consistency and safety are also excellent.
Disadvantages: Cylindrical iron-lithium-ion batteries are generally packaged in steel shells, although they are relatively safe, but the weight will be heavier, which will also make the specific energy of the lithium-ion battery pack relatively low.
●Rectangular lithium iron battery
Advantages: The packaging shells of square iron-lithium-ion batteries are mostly made of aluminum alloy and stainless steel. The inside of the battery adopts winding or laminated technology. The protection of the battery is better than that of soft-packed lithium-ion batteries. Compared with cylindrical lithium-ion batteries, safety is greatly improved.
Disadvantages: The square iron lithium-ion battery pack can be customized according to the size of the product, but it will also cause many different types of square lithium-ion batteries on the market. Too many different types of lithium-ion batteries will make it difficult to unify the process, making the automation level not high, and the monomers have large differences. There may also be groups of square lithium-ion battery packs that are much lower than that of a single lithium-ion battery. life.
