What are the key characteristics of lithium batteries?

Lithium battery characteristics: 1) High energy density has high storage energy density, which has reached 260-300Wh/kg, which is about 3-4 times that of lead-acid batteries; 2) High voltage, the working voltage of a single lithium battery is 3.7V ( Average value), equivalent to three Ni-Cd or Ni-MH batteries connected in series. 3) The pollution-free lithium battery does not contain harmful metal substances such as cadmium, lead, and mercury. 4) Long cycle life. Under normal conditions, the charge and discharge cycle of lithium batteries can exceed 500 times, while that of lithium iron phosphate reaches 5000 times. The cycle life of lithium iron phosphate in the Ningde era has reached 10,000 times. 5) No memory effect The memory effect refers to the phenomenon that the capacity of the nickel-cadmium battery decreases during the charge-discharge cycle. Lithium batteries do not have this effect. 6) Fast charging and discharging use a constant current and constant voltage charger with a rated voltage of 4.2V, which can make the lithium battery overflow in 1.5-2.5 hours; electric vehicles can be charged to 80% in half an hour using fast charging Power. Fourth, the use scenarios of lithium batteries can be divided into consumer, power (electric vehicles, electric tools, electric bicycles), and energy storage according to different use occasions.
