Lithium iron phosphate battery refers to a lithium-ion battery with lithium iron phosphate as the positive electrode material. There are various types of positive electrode materials for lithium-ion batteries, mainly including lithium cobalt oxide, lithium manganese oxide, lithium nickel oxide, ternary materials, lithium iron phosphate, etc. Among them, lithium diamond acid is currently the cathode material used in most lithium-ion batteries, while other cathode materials have not yet been mass-produced in the market due to various reasons. Lithium iron phosphate batteries are also one of the lithium-ion batteries. In terms of material principles, lithium iron phosphate is also an intercalation/deintercalation process. This principle is completely the same as lithium diamond and lithium manganese.
Performance characteristics of
lithium iron phosphate batteries:
(1) High energy density
The theoretical specific capacity of lithium iron phosphate is 170 mAh/g, and the actual specific capacity of the product can exceed 140 mAh/g (0.2C, 25 ℃);
(2) Security
Lithium iron phosphate is currently a safe positive electrode material for lithium-ion batteries; Does not contain any harmful heavy metal elements to the human body;
(3) Long lifespan
Under 100% DOD conditions, it can charge and discharge more than 2000 times; Lithium iron phosphate has good lattice stability, and the intercalation and delamination of lithium ions have little effect on the lattice, so it has good reversibility. The disadvantage is that the electron ion transfer rate is poor, and it is not suitable for high current charging and discharging, which hinders its application. Solution: Coating conductive materials on the electrode surface and doping the electrode for modification.
(4) No memory effect
(5) Charging performance
Lithium batteries using lithium iron phosphate as the positive electrode material can undergo significant charging and can be fully charged within one hour.
