Advantages of lithium ion batteries

1) High voltage  

The operating voltage of the 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) Greater than 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 about 88% of its theoretical value.  

3) Long cycle life  

Generally can reach more than 500 times, even more than 1000 times, lithium iron phosphate can reach 8000 times.  For small current discharge appliances, battery life will multiply the competitiveness of appliances.  

4) Good safety performance 

New lithium-ion batteries  

No pollution, no memory effect.  As the predecessor of Li-ion, lithium metal is easy to form dendrite and short circuit, which reduces its application field: Li-ion does not contain cadmium, lead, mercury and other elements that pollute the environment;  Part of the process (such as sintered type) ni-CD battery has a major drawback is "memory effect", which severely restricts the use of the battery, but Li-ion does not have this problem.
