Features of lithium battery:
1. Has a high weight-to-energy ratio and volume-to-energy ratio;
2. The voltage is high, the voltage of a single lithium battery is 3.6V, which is equal to the series voltage of 3 nickel-cadmium or nickel-metal hydride rechargeable batteries;
3. The self-discharge is small and can be stored for a long time, which is the most prominent advantage of the battery;
4. No memory effect, the lithium battery does not have the so-called memory effect of the nickel-cadmium battery, so there is no need to discharge the lithium battery before charging;
5. Long life, under normal working conditions, the number of charge and discharge cycles of lithium batteries is much greater than 500 times;
6. It can be charged quickly. Lithium batteries can usually be charged with 0.5 to 1 times the capacity of the current, thus shortening the charging time to 1 to 2 hours; they can be used in parallel at will;
7. Since the battery does not contain heavy metal elements such as cadmium, lead, mercury, etc., it does not pollute the environment and is the most advanced green battery in the contemporary era.
