1. Higher weight energy ratio and volume energy ratio;
2. High voltage, the voltage of a single lithium battery is 3.6V, equal to the series voltage of three nickel-cadmium or ni-MH rechargeable batteries;
3. Small self-discharge can be stored for a long time, which is the most prominent advantage of the battery;
4. No memory effect. There is no so-called memory effect of nickel-cadmium battery in lithium battery, so there is no need to discharge before charging.
5. Long life. Under normal working conditions, the number of charge/discharge cycles of lithium batteries is much more than 500 times.
6. It can be charged quickly. Lithium batteries can usually be charged with 0.5 ~ 1 times the capacity of the current, so that the charging time can be shortened to 1 ~ 2 hours;
7. Can be used in parallel at will;
8. As the battery does not contain cadmium, lead, mercury and other heavy metal elements, it is pollution-free and the most advanced green battery in modern times.
9. High cost. Lithium-ion batteries are more expensive than other rechargeable batteries.
