What are the advantages of lithium ion battery?

　　Lithium -ion battery is a secondary rechargeable battery, which consists of positive electrode, negative electrode, diaphragm, and electrolyte. Lithium -ion battery refers to the general term with lithium ion embedded compound as a positive electrode material battery. Generally, the charging current of the lithium battery is set between 0.2C and 1C. The larger the current, the faster the charging, and the greater the battery fever. Due to a series of advantages, lithium ion batteries have become mainstream batteries in the battery market, so what are the advantages of lithium ion batteries?

　　High voltage

　　The operating voltage of a single battery is as high as 3.7-3.8V (3.2V of lithium iron phosphate battery), which is 3 times that of Ni-CD and Ni-MH batteries.

　　High -energy density

　　Due to the different electrode materials, it can be calculated based on the quality, which can reach 150 ～ 200H/kg (540 ～ 720kj/kg); calculate at 250 ~ 530Wh/L (0.9 ～ 1.9kj/cm3).

　　Great output power

　　Due to different electrode materials, it can reach 300 to 1500W/kg (@20 seconds).

　　Long cycle life

　　Generally, it can reach more than 500 times, or even more than 1,000 times, and lithium iron phosphate can reach 8,000 times. For small -current discharge electrical appliances, the use period of batteries will be doubled.

　　Safe and environmentally friendly

　　No pollution, no memory effect. As the lithium battery, the predecessor of Li-ION, due to metal lithium easily forms a short circuit, it has reduced its application field: Li-ION does not contaminate the environment such as cadmium, lead, and mercury ) A major disadvantage of the Ni-CD battery is "memory effect", which seriously restrains the use of batteries, but Li-ION does not have this problem at all.

　　Self -discharge

　　The self-launch rate that was fully charged at room temperature was about 2%after 1 month of storage, which was below 25-30%of NI-CD, and 30-35%of NI-MH.

　　fast charging

　　The capacity of 1C for 30 minutes can reach more than 80%of the nominal capacity, and the phosphorus battery can be charged in 10 minutes to 90%of the nominal capacity.

　　Operating temperature

　　The working temperature is -25 ~ 60 ° C. As the electrolyte and the positive pole improve, the expectation can be widening to -40 ~ 70 ° C.
