Introduction to lithium iron phosphate battery.501825 battery

source:Industry News release time:2023-05-26 Hits: Popular:AG11 battery

　　In the crystal structure of Lifepo4, the oxygen atom is tightly stacked in six parties. PO43-tetraonal and FEO6 octopus form the spatial skeleton of the crystal. LI and Fe occupy the gap between the octopus, and P occupy the tetraonal gap. The FE occupies the common corner position of the octopus, and the li occupies the common side of the octopus. The FEO6 octopus is connected to each other on the BC surface of the crystal, and the Li6 octopus structure on the B -axis direction is connected into a chain structure. 1 Feo6 octopus and 2 LiO6 octopus and 1 PO43-tetraonal co-edge.

　　Due to the discontinuity of the FEO6 co-edge octopus network, the electronic conductivity cannot be formed; at the same time, the PO43-tetraon is limited to the volume change of the lattice, which affects the dehydration and electronic diffusion of LI+, which leads to the electronic conductivity and ion diffusion of the LIFEPO4 positive material material and the diffusion of ion. Efficiency is extremely low.

　　The theoretical than the Lifepo4 battery is higher (about 170mAh/g), and the discharge platform is 3.4V. LI+is removed between the positive and negative bipolar-embedded to achieve the charging and discharge, and the oxidation reaction occurs during charging. Li+moves out of the positive pole, embedded in the negative pole through the electrolyte, the iron changed from Fe2+to Fe3+, and the oxidation reaction occurred.
