What are the types of lithium battery cells?

　　What are the types of lithium batteries? What are the types of lithium batteries? According to the appearance of lithium battery, it can be divided into square lithium battery and cylindrical lithium battery; According to the outsourcing materials of lithium battery: aluminum shell lithium battery, steel shell lithium battery, flexible packaging battery, etc. According to the different electrolyte materials used in lithium ion batteries, lithium ion batteries can be divided into liquid lithium ion batteries (LIB) and polymer lithium ion batteries.

What are the types of lithium batteries? Lithium batteries are generally divided into two categories: lithium metal batteries: lithium metal batteries usually use manganese dioxide as the positive electrode material, metal lithium or its alloy metal as the negative electrode material, and non-aqueous electrolyte solution. Lithium ion battery: Lithium alloy metal oxide is generally used as the positive electrode material, graphite as the negative electrode material, and non-aqueous electrolyte. Generally speaking, the power batteries we talk about most are lithium iron phosphate batteries, lithium manganate batteries, lithium cobalt oxide batteries and ternary lithium batteries.

　　At present, there are three types of lithium battery cells on the market: 18650 battery, polymer battery and lithium iron phosphate battery. 18650 Battery 18650 lithium battery refers to the battery with a diameter of 18 mm and a length of 65 mm. 0 indicates a cylindrical battery. 18650 battery technology is relatively mature. The battery has stable structure, high specific capacity and excellent comprehensive performance. In addition, due to its small size, it can be used in many ranges. The disadvantage is that its safety is worse than that of polymer lithium battery, and the battery cycle times are low, only about 300 times. The difference between polymer battery and traditional lithium ion battery lies in the production process. The lithium battery is wound and soft. The polymer is overlapping and hard. With the same volume of polymer and lithium battery, the capacity of polymer is larger, about 30% higher. More safety, less explosion risk. Long service life. Charge and discharge more than 500 times. The disadvantage is high cost. Polymer batteries with the same capacity are at least 100% more expensive than 18650 lithium-ion batteries. More than is the classification and type of lithium battery. Different types of lithium batteries have different performances. Six types of lithium battery cells include lithium cobalt oxide, lithium manganate, lithium nickel cobalt manganate, lithium nickel cobalt aluminate, lithium iron phosphate, lithium titanate, etc.
