Lithium iron phosphate, the cathode material for lithium-ion batteries. This new material is not the previous lithium-ion battery cathode materials LiCoO2; LiMn2O4; LiNiMO2. its safety performance and cycle life is other materials can not be compared, these are also the most important technical indicators of power batteries. 1C charge and discharge cycle life of 2000 times. Single battery overcharge voltage of 30V does not burn and does not explode. Puncture does not explode. Lithium iron phosphate cathode material makes high-capacity lithium-ion batteries easier to use in series.
1, A long life, long-life lead-acid battery cycle life of about 300 times, up to 500 times, and lithium iron phosphate power battery, cycle life of more than 2000 times, the standard charge (5 hours rate) use, can reach 2000 times. The same quality of lead-acid batteries is "new half year, old half year, maintenance and maintenance and half year", at most 1-1.5 years, while lithium iron phosphate batteries used under the same conditions, will reach 7-8 years can be said to be "lifelong". Comprehensive consideration, the performance-to-price ratio will be more than five times that of lead-acid batteries.
2, the use of safety, lithium iron phosphate completely solve the problem of lithium cobalt and lithium manganate safety hazards, lithium cobalt and lithium manganate in a strong collision will produce an explosion on the safety of consumers' lives poses a threat, while lithium iron phosphate to strict safety tests even in the worst traffic accidents will not produce an explosion can be the most characteristic lithium battery.
3, the high current 2C fast charge and discharge, in the special charger, 1.5C charge within 40 minutes can make the battery full, starting current up to 2C, and lead-acid batteries now no such performance.
4, high-temperature resistance, lithium iron phosphate peak electrical heating up to 350 ℃ -500 ℃ and lithium manganate and lithium cobalt acid only in about 200 ℃.
5, large capacity, Tianjin Strand can produce lithium iron phosphate power battery range is the same quality lead-acid batteries 3-4 times, the advantages of electric bicycles in a moderate weight premise, a charge can run more than 100 kilometers, for commuters, a charge can be used for about a week. And lead-acid batteries equipped with electric bicycles in the vehicle weight does not exceed the standard conditions, the maximum battery capacity of 12Ah (lead-acid battery weight at this time has reached 13 kg, while the same capacity of lithium iron phosphate battery weight of only 5 kg), a charge can run up to about 50km.
6, no memory effect can be recharged battery in often in the full not put out under the conditions of work, the capacity will quickly fall below the rated capacity value, this phenomenon is called the memory effect. Like nickel-metal hydride, nickel-cadmium batteries have memory, while lithium iron phosphate batteries do not have this phenomenon, no matter what state the battery is in, can be used as it is charged, no need to first put out and then recharge.
7, small size, light weight, the same specification capacity of lithium iron phosphate battery volume is 2/3 of the volume of lead-acid batteries weight is 1/3 of lead-acid batteries.
8, green environmental protection.Lithium iron phosphate materials without any toxic or hazardous substances will not pose any pollution to the environment is recognized worldwide as a green battery, the battery both in production and use, no pollution, so the battery is included in the "Tenth Five-Year" period of "863" National Therefore, the battery is included in the "863" National High-tech Development Plan during the "Tenth Five-Year Plan", becoming a key project supported and encouraged by the state.
With China's accession to the WTO, China's electric bicycle exports will rapidly increase, and now the electric bicycle into Europe and the United States has been required to be equipped with non-polluting batteries, equipped with lead-acid batteries, electric vehicles are difficult to export, new lithium iron phosphate materials and power batteries to equip the electric vehicle, widely exported to the European market, the choice of lithium iron phosphate as an electric car battery will be a long-term strategic and wise choice!
