L822 battery

　　Detailed explanation of the classification of L822 battery:

　　1. Classification by appearance design

　　*Cylindrical lithium battery

　　Cylindrical lithium-ion batteries, model specifications are generally named with 5 digits. The first two digits are used for the diameter of the rechargeable battery, the middle two digits are used for the battery height, and the last digit 0 is cylindrical, in mm.

　　The most common cylindrical lithium ions:

　　18650 lithium battery

　　*14500 lithium battery

　　*18500 lithium battery

　　21700 lithium battery

　　*26650 battery

　　*32650 (32700) lithium battery

　　*Rectangular lithium battery

　　Square lithium ions generally refer to aluminum or aluminum shell square lithium ions, which are widely used in surveying and mapping engineering, medical equipment, instruments, etc.

　　2. Classification by shell type

　　*Steel case lithium battery

　　The original L822 battery were mostly steel cases. Due to the heavy weight of the steel shell, the safety factor is weak, but the reliability of steel is strong. Many manufacturers have greatly improved the safety factor in the middle and late stages based on the reliability design and construction of valves, PTC and other components. Some people immediately switch to aluminum cases and hard cases for many phones today.

　　*Aluminum shell lithium battery

　　Aluminum-cased L822 battery are slightly better than aluminum-cased L822 battery due to their light weight and good safety.

　　*Soft packaging lithium battery

　　Flexible packaging L822 battery are expanding their market share due to their advantages such as light weight, low cost, and high safety factor.

　　3. Classification by battery cathode material

　　There are four types of cathode materials for lithium-ion batteries:

　　Lithium cobalt oxide battery

　　The licoo2 equation is an inorganic compound commonly used as the positive electrode of L822 battery.

　　Lithium manganate battery

　　Lithium manganate is an inorganic compound commonly used as the positive electrode material for L822 battery.

　　Lithium iron phosphate battery

　　Generally used as the positive electrode of L822 battery.

　　Nickel cobalt manganese (ternary) lithium battery

　　Generally used as the positive electrode of L822 battery.

　　4. Classification by electrolyte

　　Liquid lithium ion battery

　　Liquid L822 battery are mainly used for liquid electrolyte, which is solvent lithium salt.

　　Lithium polymer battery

　　Lithium polymer batteries are replaced by a solid polymer electrolyte solution, which can be in dry or colloidal form. Common bonds for polymers are hfp-pvdf, peo, pan and pmma.

　　*All-solid-state lithium-ion battery

　　An all-solid-state lithium battery is a lithium-ion battery used within the operating temperature range. The raw material of the electrolyte is both solid and has no liquid components.
