Compared with other batteries, lithium-ion battery has the following 5 advantages:

1. High voltage

Rated open voltage is 3.6V while that of Ni-MH and Ni-Cd batteries is only 1.2V;

2. High capacity

High capacity and energy density is core value of Lithium Battery. If based on the same energy output power, lithium-ion battery is 50% lighter than Ni-MH battery and 20% smaller in volume. Yet its capacity is almost 2.5 times higher than that of Ni-CD battery and 1.5 times than Ni-MH battery;

3. low self-discharge rate

Fast charge. It only takes 1-2 hours to be fully charger. In addition, it features low capacity leakage. Even unused for 1-2 weeks, it can normally work with self-discharge rate less than 8% per month and far lower than 30% on Ni-Cd battery and 40% on Ni-MH battery;

4. Long life time

Usually can reach thousand times;

5. No memory effect

Moreover, it is characterized by no pollution, cost-effective, light weigh, which makes it become a optimal power for small-scale portable electric devices. However, easy explosion is a fatal flow of lithium battery.  For this reason, US Chicago illinois Institute of technology has made a research and greatly improved its reliability through adding 1.68% rokko ammonium epoxy triphosphate into the electrolyte.
