Which kind of battery is good for industrial backup battery?

At present, lithium iron phosphate battery is one of the most popular batteries for new energy batteries. After a long period of development, battery system technology continues to improve and perfect, and lithium iron phosphate batteries are applied to more fields. So what are its competitive advantages? Lithium iron phosphate battery 1. In terms of battery chemistry (1) In terms of battery energy density, the current lithium iron phosphate battery can reach 260～290kW.h/Kg, although it is not comparable to polymer lithium ion batteries, but It is much higher than lead-acid batteries; (2) In large current discharge, it is slightly worse than polymer, but much larger than lead-acid batteries; (3) The discharge platform and discharge efficiency are higher than lead-acid batteries; (4) In terms of high temperature resistance, according to relevant public information reports, the operating temperature can reach about 80°C, which is much better than lead-acid batteries; (5) The cycle life reaches more than 2000 times, which is much higher than the 500 times of lead-acid batteries; (6) ) Compared with lead-acid batteries, under the same electricity demand, lithium iron phosphate batteries are much smaller in volume and weight; (7) Lead-acid batteries have a passivation effect during use, but lithium iron phosphate batteries do not; 2. In terms of safety application, the P-0 bond in the lithium iron phosphate ion crystal is stable and difficult to decompose. Even at high temperature or overcharge, it will not collapse and generate heat or form strong oxidizing substances in the same structure as lithium phosphate ion. Have good security. A report pointed out that in actual operation, a small part of the samples were found to burn in acupuncture or short-circuit experiments, but no explosion occurred. In the overcharge experiment, high voltage charging that was several times higher than the self-discharge voltage was used, and it was found that there were still Explosion phenomenon. Even so, its overcharge safety has been greatly improved compared with ordinary liquid electrolyte lithium-ion batteries. 3. In terms of environmental protection and ecology, the raw materials used in lithium iron phosphate batteries are not only rich in sources, but also environmentally friendly energy materials that will not pollute the human living environment. Some raw materials used in lead-acid batteries are environmentally friendly. Cause pollution and affect the living environment of human beings.
