What are the components of lithium batteries? What are its advantages?

Lithium battery packs into parts (1) battery upper and lower cover (2) positive active material is generally lithium cobalt oxide (3) diaphragm is a special composite film (4) negative active material is carbon (5) organic electrolyte (6) battery The shell (divided into two kinds of steel shell and aluminum shell) lithium battery has the following advantages: 1) The voltage is high, and the working voltage of the single battery is as high as 3.6-3.9V, which is 3 times that of Ni-Cd and Ni-H batteries. 2) The energy is large, and the actual specific energy that can be reached at present is 100-125Wh/kg and 240-300Wh/L (2 times Ni-Cd, 1.5 times Ni-MH). With the development of technology in the future, the specific energy can be as high as 150Wh/ kg and 400Wh/L3) Long cycle life, generally can reach more than 500 times, or even more than 1000 times. Regarding low-current discharge electrical appliances, the battery life will double the competitiveness of electrical appliances. 4) Good safety performance, no pollution, No memory effect. As the predecessor of Li-ion, the lithium battery is short-circuited due to the easy formation of dendrites due to metal lithium, which reduces its application fields: Li-ion does not contain cadmium, lead, mercury and other elements that pollute the environment: some processes (For example, sintered) Ni-Cd battery has the memory effect, which seriously restricts the use of the battery, but Li-ion does not have this problem. 5) The self-discharge is small. The self-discharge rate of fully charged Li-ion at room temperature is about 10% after 1 month, which is much lower than 25-30% of Ni-Cd and 30-35% of Ni and MH.
