Lithium batteries have quickly occupied the market due to their safety, light weight, long service life, complete charge and discharge, low maintenance costs, and no memory effect. Compared with traditional lead-acid batteries, lithium batteries have the characteristics of no pollution, long service life, no memory effect, many cycles of charge and discharge, and long service life. For example, compared with lead-acid batteries of the same capacity, lead-acid batteries can be charged and discharged 400 times, while lithium batteries can be charged and discharged about 1,000 times, which is nearly three times that of lead-acid batteries, so its service life is nearly three times that of lead-acid batteries.
The advantages of lithium batteries:
1. The lithium battery has higher voltage. The average voltage of a single cell can reach or be relatively equal to the series voltage of 2-4pcs NiMH or NiCd cells.
2. The energy density of lithium batteries is also very high compared to other batteries. Lithium batteries have high energy storage density. The density of ordinary lithium batteries can reach 450-620wh/kg, which is 5-7 times that of lead-acid batteries.
3. The lithium battery is small in size. Since the volume capacity density of lithium batteries is usually about 1.5 times that of lead-acid batteries, lithium batteries are about 30% smaller than lead-acid batteries at the same capacity.
4. The lithium battery has long service life. Lithium batteries can be used for more than 6 years, and the number of normal uses exceeds 1000 times.
5. Low self-discharge and no memory effect. Lithium batteries have high power carrying capacity. In the production of lithium batteries, the lithium battery protection board can prevent the lithium battery from being overcharged and discharged.
6. Lithium battery is environmentally friendly. As lead-acid batteries have very serious pollution, they would cause environmental damage in the production process or discarding waste batteries. The lithium battery does not contain lead, mercury, cadmium and other toxic substances.
