Advantages Of Lithium-ion Batteries

1. High voltage
The working voltage of a single battery is as high as 3.7-3.8V (3.2V for lithium iron phosphate), which is three times that of Ni-Cd and Ni-MH batteries.
2. Large specific energy
The actual specific energy that can be achieved is about 555Wh/kg, that is, the specific capacity of the material can reach more than 150mAh/g (3-4 times that of Ni-Cd, 2-3 times that of Ni-MH), which is close to its theoretical value. About 88%.
3. Long cycle life
Generally, it can reach more than 500 times, or even more than 1000 times, and the lithium iron phosphate can reach 8000 times. For electrical appliances with low current discharge, the service life of the battery will double the competitiveness of the electrical appliances.
4. Good safety performance
No pollution, no memory effect. Lithium battery, the predecessor of Li-ion, because metal lithium is easy to form dendrites and short-circuit, which reduces its application field: Li-ion does not contain cadmium, lead, mercury and other elements that pollute the environment; some processes (such as sintering type ) Ni-Cd batteries have a major disadvantage of "memory effect", which seriously restricts the use of batteries, but Li-ion does not have this problem at all.
5. Small self-discharge
The self-discharge rate of fully charged Li-ion at room temperature after storage for 1 month is about 2%, which is much lower than 25-30% of Ni-Cd and 30-35% of Ni-MH.
6. Fast charging
1C charging for 30 minutes can reach more than 80% of the nominal capacity, and the iron-phosphorus battery can be charged to 90% of the nominal capacity in 10 minutes.
7. Working temperature
The working temperature is -25~45°C. With the improvement of electrolyte and positive electrode, it is expected to be extended to -40~70°C.
