Simple analysis of the advantages and disadvantages of lithium batteries

1. Green and environmentally friendly, no matter it is processed, used or scrapped, it does not contain or exist any toxic and harmful heavy metal elements, lead, mercury, cadmium and other substances. 2. The service life of lithium batteries is relatively long. The service life of a lithium iron phosphate battery with a positive electrode exceeds 6 years. The battery with positive electrode is charged and discharged with 1CDOD, and there are 1000 application records. 3. Lithium battery high-voltage platform: the voltage of single cells is 3.7V or 3.2V, which is equivalent to the series voltage of three nickel-cadmium batteries or nickel-hydrogen batteries. 4. The charge and discharge capacity of lithium iron phosphate batteries for electric vehicles can reach 15×30°C, which is convenient for high-intensity start-up and acceleration. 5. The energy density of lithium batteries is relatively high. The high energy storage density has reached 460-600Wh/kg, which is 6-7 times that of lead-acid batteries. 6. The weight of lithium battery is lighter than that of lead-acid battery. The weight of lithium battery is about 1/5 or 6. of the same volume of lead-acid battery. 7. The self-discharge rate is low and there is no recall effect. Very adaptable. It can be used in the environment of -20~60~C, and can be used in the environment of -45~C after production. Disadvantages 1. Lithium-cobalt data lithium battery cannot be discharged under high current, and its safety is poor. 2. The safety of lithium batteries is poor and there is a danger of explosion. 3. High processing requirements and high cost. 4. All lithium batteries must maintain circuits to guard against overcharge and discharge.
