A single battery can reach an average voltage of 3.7V or 3.2V. Relatively equal to 2-4 NiMH batteries or nickel-isolated batteries in series voltage. If the customer requires the use of battery voltage over, then the choice of lithium-ion batteries are also easy to facilitate the composition of lithium-ion battery pack, convenient and fast to enhance the voltage of lithium-ion batteries.
Lithium-ion batteries have high storage energy density, currently commonly used lithium-ion battery density can reach 450-620Wh/kg, is 5-7 times more than lead-acid batteries. If people choose the battery will also take into account a very important issue, that is, pollution.
The weight of a lithium-ion battery is about 5-6 times that of a lead-acid battery. Although the weight of lithium-ion batteries and polymer lithium-ion batteries is not much difference in weight. But look at the capacity and life, people are going to choose lithium-ion batteries.
A lithium-ion battery life if no accidents can be used for more than 6 years, up to 9 years. The normal number of uses in more than 1000 times. If no accident occurs, the number of uses can reach more than 1500 times.
The production of lithium-ion batteries to add protection plates can make lithium-ion batteries have an overcharge and overdischarge effect. The lithium-ion battery itself has a high power tolerance, and the lithium-ion battery selected for electric vehicles can reach a high effect capacity of 15-30C charging and discharging, in order to accelerate the high-intensity start on the car.
Lithium-ion battery is green and environmentally friendly
Lithium-ion batteries do not contain lead, mercury, cadmium toxic substances.
