About the durability of lithium-ion batteries

A lithium battery is a type of battery using a lithium metal or a lithium alloy as a negative electrode material and using a nonaqueous electrolyte solution. The earliest lithium battery came from the great inventor Edison.

Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal are very demanding on the environment. Therefore, lithium batteries have not been used for a long time.

Characteristics of lithium battery:

1. It has higher weight-to-energy ratio and volume-to-energy ratio;

2. The voltage is high and the voltage of the single-cell lithium battery is 3.6V, which is equal to the series voltage of 3 nickel-cadmium or nickel-hydrogen rechargeable batteries;

3. Self-discharge can be stored for a long time, this is the most outstanding superiority of the battery;

4. No memory effect. Lithium batteries do not have the so-called memory effect of nickel-cadmium batteries, so lithium batteries do not need to be discharged before charging;

5. Long life. Under normal working conditions, the number of charge/discharge cycles of the lithium battery is much greater than 500 times;

6. Can be quickly charged. The lithium battery can usually be charged with a current of 0.5 to 1 times, so that the charging time is shortened to 1 to 2 hours;

7. Can be used in parallel;

8. Because the battery does not contain heavy metal elements such as cadmium, lead, mercury, etc., it is environmentally friendly and is the most advanced green battery in the world;

9. High cost. Lithium batteries are more expensive than other rechargeable batteries.
