What are the components and application characteristics of ternary lithium batteries?

　　1. Lithium cobalt oxide

　　(1) Features: Small size, light weight; No memory effect; Long cycle life (greater than 1000 cycles); High temperature resistance (up to 300 ° C or above); Cheap prices, etc

　　(2) Application field: In digital products such as mobile phones, digital cameras, and other power management chips; Charging control circuit board and charger in electric tools

　　(3) Disadvantage: Low energy density

　　2. Lithium manganate

　　(1) Feature: High energy density

　　(2) Application field: In laptop power management modules and chargers; In the power battery pack used in automobiles (for starting engines) and in the power battery pack used in electric bicycles (for driving motors), and so on Lithium manganese oxide has a large capacity, but its price is also relatively high! The commonly used laptop power management module on the market currently uses lithium manganese oxide batteries as energy storage devices!

　　3. Nickel–metal hydride battery

　　(1) Characteristic: Higher than energy

　　(2) Advantages: Good safety

　　(3) Disadvantage: High cost

　　4. Lithium iron phosphate battery

　　(1) Characteristics

　　The energy density of Lithium iron phosphate battery is very high. Because its electrode active material is phosphate, it is called Lithium iron phosphate battery or iron phosphorus aluminum secondary alkaline battery. It has the following main advantages: (1) no memory effect; (2) Low self discharge; (3) Wide working temperature range; (4) Long service life; (5) Capable of fast charging and discharging with high current; (6) Good environmental friendliness. (7) Good economic performance. (8) Good safety performance. (9) Good shock resistance. (10) Excellent low-temperature performance.

　　(2) Application field

　　The most commonly used in the electric vehicle industry is lead-acid maintenance free batteries, which have a relatively long service life and low cost and are suitable for mass production and manufacturing. However, due to the limited storage capacity of lead-acid and its susceptibility to liquid leakage, dangerous accidents can occur. Therefore, the country has explicitly prohibited the use of lead-acid storage equipment.
