What are the advantages of lithium batteries?

　　1, the lithium battery voltage platform is high, the uniform voltage of the single battery is 3.7V or 3.2V, which is about equal to the series voltage of 3 nickel-cadmium batteries or nickel-metal hydride batteries, which is easy to form a battery power group. 2. Lithium batteries have a high energy density compared to batteries. With a high storage energy density, it has reached 460-600Wh/kg, which is about 6-7 times that of lead-acid batteries.

　　3. Compared with lead-acid batteries, lithium batteries are light in weight, and the weight is about 1/5-6 of lead-acid products under the same volume.

　　4, lithium battery service life is relatively long, the service life can reach more than 6 years, lithium iron phosphate as a positive battery with 1CDOD charge, there is a record of 1000 times. 5, with high power acceptance, during which the lithium ferrous phosphate lithium-ion battery used in electric vehicles can reach 15-30C charging and discharging ability, which is convenient for high-intensity acceleration.

　　6, low self-discharge rate, no memory effect, often used in daily electronic product power supply.

　　7, lithium battery up and down docility is strong, can be used in the environment of -20℃ -60℃, through the process of disposal, can be used in the environment of -45℃.

　　8, green environmental protection, regardless of consumption, use and scrap, does not contain, does not produce any lead, mercury, cadmium and other toxic and harmful heavy metal elements and substances.

　　What are the disadvantages of lithium batteries?

　　1, lithium batteries have poor safety, there is a risk of explosion.

　　2, lithium cobalt acid lithium batteries can not be large electric exile, poor safety.

　　3, lithium batteries need to maintain the line to prevent the battery from being overcharged and discharged.

　　4, high consumption requirements, high cost.
