Characteristics of lithium batteries

 Characteristics of lithium batteries

Lithium batteries, especially with their energy density ratio and safety stability, have directly pushed lead-acid or colloidal batteries out of the historical stage. Based on advantages such as temperature adaptability, environmental friendliness, and life cycle, lithium batteries have the following characteristics:

1. High weight to energy ratio and volume to energy ratio;

2. High voltage. The voltage of a single lithium battery is 3.6V, which is equal to the series voltage of three nickel cadmium or nickel hydrogen rechargeable batteries;

3. Self discharge can be stored for a long time, which is a prominent advantage of lithium batteries;

4. There is no memory effect. The lithium battery does not have the so-called memory effect of Nickel–cadmium battery, so the lithium battery does not need to be discharged before charging;

5. Long life. Under normal working conditions, the number of charging and discharging cycles of lithium batteries exceeds 500 or more.

6. It can be charged quickly. The charging capacity of a typical lithium battery can be 0.5-1 times, which can shorten the charging time to 1-2 hours;

7. It can be used in parallel at will;

8. Due to the fact that batteries do not contain heavy metal elements such as cadmium, lead, and mercury, they are not polluting the environment and are currently very advanced green batteries;

9. High cost. Compared to other rechargeable batteries, lithium batteries are more expensive.
