What are the advantages of lithium iron phosphate batteries for industrial backup batteries?

1. In terms of battery chemistry performance (1) The energy density of the battery is currently 260～290kW.h/Kg for lithium iron phosphate. Although it is not comparable to polymer lithium batteries, it is much higher than lead-acid batteries. 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 related Public information reports that 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 applications, lithium iron phosphate batteries The P-0 bond in the crystal is stable and difficult to analyze. Even at high temperature or overcharge, it will not collapse and generate heat or form strong oxidizing substances with the same structure as lithium phosphate, so it has good safety. A report pointed out that in the actual operation, a small part of the samples were found to burn, but no explosion occurred. In the overcharge test, a high voltage charge that was several times higher than the self-discharge voltage was used, and it was found that there was still Explosion phenomenon. Even so, its overcharge safety has been greatly improved compared with ordinary liquid electrolyte lithium sulphate batteries. 3. From the perspective 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 cause pollution to the human living environment. Some raw materials used in lead-acid batteries are harmful to the environment. Pollution affects the living environment of human beings. 4. Iron phosphate batteries can be used in cascades. For example, old batteries replaced from new energy vehicles have been scientifically tested and repaired, and can be applied to the next level of backup power supply that does not require high electrical performance, such as information base station backup power. Etc., lead-acid batteries and nickel-metal hydride batteries cannot. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
