High safety performance The PO bond in the lithium iron phosphate crystal is stable and difficult to decompose. Even at high temperature or overcharge, it will not collapse and heat up like lithium cobalt oxide or form strong oxidizing substances. The decomposition temperature of lithium iron phosphate is about 600 ℃, so Have good security. Although there have been burning and explosions in the case of overcharging, the safety of overcharging has been greatly improved compared with ordinary liquid electrolyte lithium cobalt oxide batteries and ternary batteries. long life The cycle life of a lead-acid battery is about 300 times, up to about 500 times, while a lithium iron phosphate power battery has a cycle life of more than 2000 times, and it can be used for 2000 times with a standard charge (0.2C, 5 hours). Lead-acid batteries of the same quality are "new half a year, half a year old, and half a year repaired", which is 1 to 1.5 years at most, while lithium iron phosphate batteries used under the same conditions will have a theoretical life of 7 to 8 years. . Considering comprehensively, the performance-price ratio is theoretically more than 4 times that of lead-acid batteries. High-current discharge can quickly charge and discharge high current 2C. With a dedicated charger, the battery can be fully charged within 40 minutes of 1.5C charging, and the starting current can reach 2C, but lead-acid batteries have no such performance.Q1.
