The development of lithium batteries is getting more and more, and the reasons and some of its advantages are inseparable. Lithium batteries have high voltage and light weight. The average voltage of a single cell can reach 3.7V or 3.2V. It is equivalent to the series voltage of 2-4 nickel-hydrogen batteries or nickel separator cells. If the customer requires the voltage of the battery to pass, then the lithium battery is also convenient to form a lithium battery pack, which is convenient for quickly increasing the voltage of the lithium battery.
The energy and density of lithium batteries are also high for other batteries. Lithium batteries have high energy storage density. Currently, the density of lithium batteries can reach 450-620Wh/kg, which is 5-7 times that of lead-acid batteries. If people choose batteries, they will also consider a very important issue, that is, pollution.
Compare against battery weight. A lithium battery weighs about 5-6 times the weight of a lead-acid battery. Although the weight of the lithium battery is not much different from the weight of the polymer lithium battery. But looking at capacity and longevity, people will choose lithium batteries.
Lithium batteries have a long service life, and a lithium battery can last for more than 6 years without accidents for up to 9 years. The normal number of uses is more than 1000 times. If the number of accidental uses does not occur, it can reach 1500 times or more.
Self-discharge is low and there is no memory effect. The production of a lithium battery to the lithium battery body with a protective plate can make the lithium battery have an overcharge and over discharge effect. The lithium battery itself has high power carrying capacity, and the lithium battery selected by the electric vehicle can achieve a high effect capacity of 15-30C charge and discharge, so as to accelerate the high-intensity start of the vehicle.
Lithium batteries are environmentally friendly, and lithium batteries do not contain lead, mercury or cadmium.
