1, high lithium battery voltage, light in weight. Average a monomer battery voltage can reach 3.7 V or 3.2 V relatively equal to 2-4 ni-mh battery or nickel series voltage of the battery. If the customer requires the use of the battery voltage, then use lithium batteries lithium-ion battery pack is easy and convenient, fast and convenient to promote lithium battery voltage.
　　2, lithium-ion battery energy and density for other battery is also high. Lithium battery with high energy storage density, the current commonly used lithium battery density can reach 450-620 wh/kg, 5 to 7 times that of lead-acid batteries. If people choose battery will also consider a very important problem, which is pollution.
　　3, for the battery weight to contrast. A lithium battery weight about 5 to 6 times of lead-acid batteries. Although the weight of the lithium battery and the weight of the polymer lithium battery are not much difference. But the capacity and life, people are will choose of lithium-ion batteries.
　　4, the use of lithium battery life for a long time, a lithium battery service life if without accident can use 6 years, for nine years. The normal use of the more than 1000 times. If no accident usage can reach more than 1500 times.
　　5, low self-discharge, and no memory effect. In the production of lithium batteries on lithium batteries and can make the lithium battery protection board has a charge discharge effect. Lithium-ion batteries have the endurance, high power electric car use lithium battery can reach 15 to 30 c charge-discharge efficiency should be ability, so that the car starting and accelerating the high strength.
　　In 6, green environmental protection, lithium-ion batteries, lithium batteries do not contain lead, mercury, cadmium is poisonous substances.
