Since the advent of lithium batteries, the research and development work around them has been going on continuously. The cathode material of lithium-ion batteries has always been a topic of debate. Today we will talk about the 10kwh LiFePO4 battery with lithium iron phosphate (LiFePO4) as the cathode material.
The full name of 10kwh LiFePO4 battery should be 10kwh lithium iron phosphate lithium-ion battery, which is too long, and is referred to as lithium iron phosphate battery for short. Because its performance is particularly suitable for power applications, the word "power" is added to the name, that is, lithium iron phosphate power battery. Some people also call it "lithium-iron power battery", which uses LiFePO4 material as the cathode cost.
At present, the main cathode materials used for lithium ion batteries are: LiCoO2, LiMn2O4, LiNiO2 and LiFePO4. Among the metal elements that make up the positive electrode material of the battery, cobalt (Co) is the most expensive and has little storage capacity, nickel (Ni) and manganese (Mn) are cheaper, and iron (Fe) is the cheapest. The prices of cathode materials are also in line with those of these metals. Therefore, the 10kwh LiFePO4 battery made of LiFePO4 cathode material should be the cheapest.
The advantage and trend of 10kwh LiFePO4 battery for solar energy storage system.
The advantages are better safety; longer service life; no heavy metals and rare metals (low raw material cost); no memory effect; high temperature resistance; can easily pass acupuncture experiments.
The slight potential is that lithium iron phosphate has some performance defects, such as low tap density and compaction density, the same battery capacity, lithium iron phosphate battery is heavier in weight and larger in volume. In addition, the 10kwh LiFePO4 battery basically cannot be recycled after being scrapped, and has no recyclable value. So grade B cells from recycled EV cars, the cycle life is very short and unstable. Buying grade B recycled cells likes buying lottery tickets. You never know when the battery will stop working.
PCenergsys manufacture for 10kwh LifePo4 battery have insisted on grade A LifePo4 cells, the longest lifespan is over 6 years.
