Lithium iron phosphate is an important cathode material for lithium-ion batteries. Due to its high theoretical specific capacity, low manufacturing cost, good cycle performance, and environmental friendliness, it has become a hot topic in the current research of cathode materials for power batteries.
A lithium-iron-phosphate battery refers to a battery using lithium iron phosphate as a positive electrode material, which has the following advantages and characteristics. The requirements for battery assembly are also stricter and need to be completed under low-humidity conditions.
Lithium iron phosphate (LFP) batteries have gained widespread recognition for their exceptional thermal stability, remarkable cycling performance, non-toxic attributes, and cost-effectiveness. However, the increased adoption of LFP batteries has led to a surge in spent LFP battery disposal.
Owing to the low electrical conductivity (<10−9 S cm −1) of the ordered olivine structure, small lithium iron phosphate particles, in intimate contact with conductive carbon, must be used to avoid inactive areas in the bulk electrode and to reduce the distance for Li + transport in the solid.
The impact of lithium iron phosphate positive electrode material on battery performance is mainly reflected in cycle life, energy density, power density and low temperature characteristics. 1. Cycle life The stability and loss rate of positive electrode materials directly affect the cycle life of lithium batteries.
Compared with other lithium battery cathode materials, the olivine structure of lithium iron phosphate has the advantages of safety, environmental protection, cheap, long cycle life, and good high-temperature performance. Therefore, it is one of the most potential cathode materials for lithium-ion batteries. 1. Safety
