&#;&#;The significance of lithium iron phosphate battery pack
&#;&#;Discharge voltage on the smooth, safe (no combustion, no explosion), life (number of cycles), no pollution of the environment, lithium iron phosphate battery is the best, is currently the best high current output power battery.
&#;&#;The advantages of lithium iron phosphate battery pack
&#;&#;&#; long service life, long-life lead-acid battery cycle life of about 300 times, the highest is 500 times, while lithium iron phosphate power battery, cycle life of more than times, the standard charge (5 hours rate) use, can reach times.
&#;&#;&#; High temperature performance is good, lithium iron phosphate electrical peak of 350 &#; -500 &#; and lithium manganese acid and lithium cobalt acid only in about 200 &#;. Wide operating temperature range (-20C - +75C), with high-temperature resistance Lithium iron phosphate peak electrical heating up to 350 &#; -500 &#; and lithium manganate and lithium cobalt acid only in about 200 &#;.
&#;&#;&#; Safe and reliable, lithium iron phosphate crystals in the P-O bond is solid, difficult to decompose, even at high temperatures or overcharge will not be like lithium cobaltate structure collapse heat or the formation of strong oxidizing substances, so has a good safety.
&#;&#;&#;No memory effect. When rechargeable batteries are operated under conditions where they are often filled but not discharged, the capacity will quickly fall below the rated capacity, a phenomenon called the memory effect. Such as nickel-metal hydride, nickel-cadmium batteries have memory, while lithium iron phosphate packs do not have this phenomenon, no matter what state the battery is in, can be used as it is charged, no need to first discharge and then recharge.
&#;&#;&#;Small size, light weight, large capacity, the same 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, with greater capacity than ordinary batteries (lead-acid, etc.).
&#;&#;&#;Green environmental protection, lithium battery pack is considered to be free of any heavy metals and rare metals (NiMH batteries require rare metals), non-toxic (SGS certification through), non-polluting, in line with European RoHS regulations, for the absolute green battery certificate.
&#;&#;&#; Charge and discharge characteristics of good, lithium battery pack charge and discharge electrical energy conversion efficiency can be greater than 97%, lead-acid battery charge and discharge electrical energy conversion efficiency of about 80%. For the same fully charged lithium iron phosphate battery, at the same temperature, using different multiples of the discharge current, its discharge output characteristics are very stable.
&#;&#;&#; fast charging: can be high current 2C fast charging and discharging, in a special charger under 1.5C charging within 40 minutes to fill the battery, starting current up to 2C, while the lead-acid battery now no such performance.
&#;&#;Disadvantages of lithium iron phosphate packs

&#;&#;2, lithium iron phosphate battery pack has some performance defects, low temperature performance, low density of vibration and compaction density, resulting in a lower energy density of lithium-ion batteries.
&#;&#;3, the material preparation cost and the manufacturing cost of the battery is high, the battery yield is low and the consistency is poor.
&#;&#;4, intellectual property issues. At present, the basic patent of lithium iron phosphate is owned by the University of Texas, and the patent of carbon cladding is applied for by the Canadians. These two basic patents can not be bypassed, if the cost is calculated on the patent royalties, then the product cost will be further increased.
&#;&#;How lithium battery packs should be recycled
&#;&#;To realise the secondary use of power batteries, a full life cycle monitoring system for power batteries needs to be established to evaluate the health status of the batteries in real time. The evaluation and monitoring of the battery should be placed in the whole life cycle of the battery, rather than waiting for the battery to be eliminated before testing and screening. Commonly used methods to resource waste lithium batteries include hydrometallurgy, pyrometallurgy and mechanical-physical methods. Compared to hydrometallurgy and pyrometallurgy, mechanophysical methods do not require the use of chemical reagents and consume less energy, making them an environmentally friendly and efficient method.
