1. High voltage
The operating voltage of a single battery is as high as 3.7-3.8V (3.2V of lithium iron phosphate), which is 3 times that of Ni-CD and NI-MH batteries.
2. Great energy
The actual ratio that can be achieved is about 555Wh/kg, that is, the material can reach a capacity of 150mAh/g (3-4 times to NI-CD, 2-3 times to NI-MH), which is close to its theory About 88%of the value.
3. Long circulation life
Generally, it can reach more than 500 times, or even more than 1,000 times, and lithium iron phosphate can reach more than 2,000 times. For small -current discharge electrical appliances, the use period of batteries will double the competitiveness of electrical appliances.
4. Good safety performance
No pollution, no memory effect. As a lithium battery in the predecessor of Li-ION, because metal lithium is easy to form a short circuit, it has reduced its application field: Li-ION does not contain elements that contaminate the environment such as cadmium, lead, mercury and other pollution elements. : A major disadvantage of some processes (such as sintering) Ni-CD batteries is "memory effect", which seriously restrains the use of batteries, but Li-ION does not have this problem at all.
5. Self -discharge small
The self-launch rate that was fully charged at room temperature was about 2%after 1 month of storage, which was greatly lower than the 25-30%of NI-CD, and 30-35%of NI-MH.
6. 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.
7. Work temperature
The working temperature is -25 ~ 45 ° C. As the electrolyte and the positive pole improve, the expectation can be widening to -40 ~ 70 ° C.
