Lithium batteries have 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 specific energy is large, and the actual specific energy that can be achieved 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, Even more than 1000 times. Regarding small 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, lithium batteries are easy to form due to metal lithium The dendrite is short-circuited, reducing its scope of use: Li-ion does not contain cadmium, lead, mercury and other elements that pollute the environment: a major disadvantage of Ni-Cd batteries of some processes (such as sintering) is the memory effect , Which severely restricts the use of batteries, but Li-ion does not have this problem at all. 5) The self-discharge is small. The self-discharge rate of Li-ion overflowing at room temperature after 1 month storage is about 10%, which is much lower than 25-30% of Ni-Cd and 30-35% of Ni and MH. 6) It can be charged and discharged quickly, and the capacity of 1C charging can reach more than 80% of the nominal capacity. 7) The working temperature range is high, the working temperature is -25~45°C. With the improvement of electrolyte and positive electrode, it is expected to be expanded to -40~70°C. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
