What are the life characteristics of large-capacity lithium batteries?

What are the characteristics of the service life of large-capacity lithium batteries? Analysis of the advantages and disadvantages of large-capacity lithium batteries in Anhui Province. The development of electric vehicles is one of the effective means to solve the energy crisis and environmental pollution. Currently, most companies choose lithium batteries as their power source because they are favored by users because of their small size, light weight, and large capacity. Large-capacity and high-power lithium batteries are ideal energy storage power sources for electric vehicles. This article will analyze the characteristics, advantages and disadvantages of the life of large-capacity lithium batteries. In the analysis of the large-capacity lithium battery, it is found that the rechargeable battery has a longer life, and the large-capacity lithium battery can be recycled more than 1000 times. Although they are more expensive than dry batteries, they are more cost-effective if used frequently. The charging capacity of large-capacity lithium batteries is lower than that of alkaline manganese batteries or zinc-carbon batteries of the same specifications. Because the discharge voltage of a large-capacity lithium battery is almost constant, it is difficult to predict when the discharge will end. At the end of the discharge, the battery voltage suddenly drops. Advantages and disadvantages of large-capacity lithium batteries: 1. Large-capacity lithium batteries have high energy. The energy storage density is high, reaching 460-600wh/kg, which is about 6-7 times that of lead-acid batteries. 2. Large-capacity lithium battery has a long service life, up to more than 6 years. 3. The self-discharge rate of large-capacity lithium battery is very low, which is one of the most prominent advantages of the battery. At present, it can generally reach less than 1%/month, less than 1/20 of Ni-MH batteries; 4. Large-capacity lithium batteries are environmentally friendly. No matter it is processed, used or scrapped, there is no or no toxic and harmful heavy metal elements and substances such as lead, mercury, and cadmium. 5. The processing of large-capacity lithium batteries does not consume water, which is very beneficial to my country's water shortage. For example, a large-capacity robot battery can continue to power the robot, and it can also provide a large-scale discharge function, which is not terrible. Disadvantages: 1. The safety of large-capacity lithium batteries in Anhui is poor and there is a danger of explosion. 2. The lithium battery should protect the circuit to prevent the battery from overcharging and discharging. 3. High processing requirements and high cost.
