Lithium battery is popular

Why are lithium batteries so popular? What is the reason for the popularity of lithium batteries? Let’s take a look at the following:

1. The lithium battery has high voltage and light weight. The average voltage of a single cell can reach 3.7 v or 3.2 v. Relatively equal to the series voltage of 2 - 4 nickel-metal hydride batteries or nickel separator batteries. 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 and quick to increase the voltage of the lithium battery.

2. The energy and density of lithium batteries are also high for other batteries. Lithium batteries have high energy storage density, and the current lithium battery density can reach 450 - 620 wh / 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.

3. for the battery weight to compare. 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.

4. lithium battery life is very long, a lithium battery life can be used 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 use does not occur, it can reach more than 1500 times.

5. low self-discharge, and 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.

6. Lithium batteries are green and environmentally friendly. Lithium batteries do not contain lead, Mercury, and cadmium toxic substances.
