About the advantages and disadvantages of lithium-ion batteries

Source: 2020 - 03 - 23 but hits: first lithium battery's advantages, the advantages and disadvantages of 1. Lithium battery high voltage platform: a single battery voltage is 3. 7 v or 3. 2 v, is approximately equal to three pieces of nickel cadmium battery or nickel metal hydride batteries in series voltage, is conducive to the formation of the battery power pack; 2. Compared with batteries, lithium batteries with higher energy density. Has the high energy storage density, 460 - 600 wh/kg, which is about 6 - of lead-acid batteries Seven times. 3. Compared with lead-acid batteries, lithium batteries light weight, under the same volume of about 1/5 of the lead acid products, 6; 4. Lithium battery service life relatively long, the service life in 6 years. Is extremely lithium iron phosphate batteries, press 1 cdod charging, using the record 1000 times; 5, have high power capacity, the electric car with iron phosphate lithium-ion batteries can reach 15 - 30 c of charge and discharge capacity, the realization of high intensity is accelerated; 6. Low self-discharge rate, no recall effect; 7. Lithium battery for high and low temperature adaptability is strong, can be in - Used in 20 ℃ to 60 ℃ environment. After processing, can be in - 45 ℃ environment use; 8, green environmental protection, regardless of the production, use and waste, excluding, without any poisonous and harmful heavy metals such as lead, mercury, cadmium and material. 1 second, defects. The lithium battery security is poor, there is a risk of explosion. 2, lithium battery of lithium cobalt oxide large current data does not discharge, poor safety. 3, lithium battery need maintenance lines, avoid battery overcharge and over discharge. 4, high production requirements, cost is high.
