About ten of the advantages of large capacity lithium battery

Source: 2020 - 04 - 19 clicks: through The Times ten of the advantages of large capacity lithium battery analysis: 1. The large capacity lithium battery energy is high. Has the high energy storage density, 460 - 600 wh/kg, which is about 6 - of lead-acid batteries Seven times. 2. Large capacity lithium battery service life is long, the service life of 6 years. The anode for lithium iron phosphate batteries 1 c ( 100% dod) Charge and discharge, reusable 10000 times. 3. Large capacity lithium battery rated voltage is high ( Single working voltage of 3. 7 v or 3. 2v) , is approximately equal to three pieces of nickel cadmium or nickel metal hydride rechargeable batteries in series voltage, is conducive to the formation of the battery power pack; 4. The electric car with iron phosphate lithium-ion battery with high power capacity, can reach 15 - 30 c of charge and discharge capacity, easy to start, acceleration, high strength; 5. Large capacity lithium battery self-discharge rate is very low, this is the most outstanding one of the advantages of the battery. Currently, it generally can achieve less than 1% per month, less than 1/20 of the nimh batteries; 6. The large capacity lithium battery light weight, is 1/6 of the weight, the same capacity of lead acid product 1/5. 7, high and low temperature, strong adaptability, can be in - 20℃- Using 60 ℃ environment, can be in - after processing 45 ℃ environment use; 8, the large capacity lithium battery of green environmental protection, regardless of the production, use and scrap, and do not contain, does not produce any poisonous and harmful heavy metals such as lead, mercury, cadmium and material. 9, the large capacity lithium battery production basically no water, for water shortage of China, is very useful, for example, large capacity battery can last for robots, but also can provide a lot of discharge function, is not very strong. 10. Large capacity lithium battery than can refers to the unit weight or volume of energy. Than to Wh/kg and Wh/L said. Wh is energy units, W is a W, h is hours; The kilogram is kg ( Weight unit) L L ( Volume unit) 。 Five, the large capacity lithium battery defect analysis and summary of the analysis of the large capacity lithium battery has some deficiencies, mainly reflected in the following four aspects. 1. Lithium battery safety is poor, with explosion danger. 2, lithium ion battery of lithium cobalt oxide can't discharge large current, poor safety. 3, lithium-ion battery needs protection circuit, prevent the battery overcharge discharge. 4. High production requirements, cost is high.
