What is a lithium iron phosphate battery ?
Lithium iron phosphate battery refers to a lithium ion battery using lithium iron phosphate as a positive electrode material. The cathode materials of lithium-ion batteries mainly include lithium cobalt oxide, lithium manganate, lithium nickel oxide, ternary materials, lithium iron phosphate, etc.
Lithium Iron Phosphate Batteries: Introduction
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 batteries, 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 lithium-ion battery made of LiFePO4 cathode material should be the cheapest.
Lithium Iron Phosphate Batteries: Advantages
There is another issue to consider when choosing a battery, and that is the charge-discharge cycle. Simply put, it is the number of times the battery can be fully charged-discharged before it is scrapped. Traditional nickel-metal hydride batteries or lead-acid batteries may only have a few hundred charge-discharge cycles, which is really acceptable compared to their selling price. Lithium iron phosphate batteries have about a thousand charge-discharge cycles.
At the same time, the self-discharge performance of lithium iron phosphate batteries is also excellent. Like the most traditional nickel-cadmium battery, it will discharge light if it is not charged for a month. Lithium iron phosphate batteries basically take six months or longer to discharge power.
In addition, don't forget that lithium iron phosphate batteries are more environmentally friendly than other types of batteries. Although the process of producing batteries will also produce pollution, it is relatively clean in comparison. The above is the introduction to "what is a lithium iron phosphate battery, I hope it will help you.
