Source: 2020 - 03 - 26 but hits: lithium iron phosphate battery how many? Why are an increasing number of people use lithium iron phosphate battery pack? With the development of lithium iron phosphate battery pack and the evolution of technology, the use of lithium ion battery is more and more widely, the current domestic electric cars mainly use lithium iron phosphate batteries. Lithium iron phosphate battery has won the user's favorite, today let's energy-efficient appliances the author together with you to fully understand the advantages of lithium iron phosphate batteries. What is the lithium iron phosphate batteries? Lithium ion batteries is mainly composed of the positive and negative electrolyte and clearance. Lithium ion battery anode, cathode and electrolyte can differ depending on the material and make a battery has different performance and terminology. More common in the market of lithium battery is lithium cobalt oxide ( LiCoO2) And manganese acid lithium ( LiMn2O4) 。 Lithium iron phosphate battery is a lithium battery, mainly used in power system, such as electric vehicles, military, aerospace, power tools, UPS, etc. Why are an increasing number of people use lithium iron phosphate battery pack? 1. Higher energy than. Lithium iron phosphate battery energy storage density high, 460 - 600 wh/kg, which is about 6 - of lead-acid batteries Seven times. 2. Life is long, the lithium iron phosphate battery packing life can reach more than 6 years; 3. High additional voltage ( A single working voltage of 3. 7 v3。 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. High power capacities, including electric cars, lithium iron phosphate battery can reach 15 - 30 c to charge and discharge capacity, facilitate high strength starting and accelerating; 5. Low self-discharge rate is one of the most prominent advantages of batteries, generally can reach 1% / month, far less than 25 - nickel cadmium, nickel, MH 30% - 35%; 6. Light weight. The same volume of lithium iron phosphate is about 1/5 of the lead-acid battery, battery weight 1/6. 7. Applicability, high and low temperature - 20° C - 60° Can use C, - 45° C can be used by process; 8. Lithium-ion battery pack is green environmental protection, consumption, use or waste, do not contain or consume any poisonous and harmful heavy metal elements and substances, such as lead, mercury, cadmium, etc. ; 9. Security, lithium iron phosphate battery completely solve the safety hidden trouble of lithium cobalt oxide and manganese acid lithium. Lithium cobalt oxide and manganese acid lithium will explode in a fierce collision. 10. Lithium iron phosphate battery has no memory effect, no this kind of phenomenon, no matter in what state, can be free to use, do not need to put the whole battery recharging. At present, China's new energy automotive safety planning, in a short period of time can not reach the level of the tesla, using ternary lithium battery as motive power sources of new energy vehicles there is a huge security risks. As for the passengers' safety, even if is 100000th of a security risk is unacceptable. The stability of the lithium iron phosphate batteries at high temperature can reach more than 390, guarantees the high safety of the battery. Not overcharge, short circuit or collision over-heated, or go out. It is easy to passed the test of the needle. This kind of security features, to our country is still in the immature stage of the new energy automotive industry, is the most appropriate. Under the conditions of current relevant subsidy policy, the first time to buy new energy vehicles have corresponding government subsidies, but the second time to buy batteries without subsidies. Ternary lithium battery in the use of new energy vehicles cycle, need to convert two batteries, will greatly increase the economic burden of the user, and will not be accepted by the end user. From China's new energy automobile consumption characteristic and consumption habits, ternary lithium batteries are not suitable for China's new energy vehicle power battery. Future of lithium iron phosphate battery: the lithium iron phosphate battery profession wide prospect of market, lithium battery consumption enterprise competition in the future. As lithium batteries more and more application in all fields, especially in electric vehicles, new energy, military and other fields gradually introduced, lithium battery packaging industry innovation speed is accelerated, the retrofit, the fierce competition in the future.
