As lithium ions are removed during the charging process, it forms a lithium-depleted iron phosphate (FP) zone, but in between there is a solid solution zone (SSZ, shown in dark blue-green) containing some randomly distributed lithium atoms, unlike the orderly array of lithium atoms in the original crystalline material (light blue).
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 is a common and inexpensive polyanionic compound extensively used as a battery cathode. It has a long life span, flat voltage charge-discharge curves, and is safe for the environment. Sun et al. prepared 3D interdigitated lithium-ion microbattery architectures using concentrated lithium oxide-based inks .
Multiple lithium iron phosphate modules are wired in series and parallel to create a 2800 Ah 52 V battery module. Total battery capacity is 145.6 kWh. Note the large, solid tinned copper busbar connecting the modules together. This busbar is rated for 700 amps DC to accommodate the high currents generated in this 48 volt DC system.
The synthesis of lithium-iron-phosphate is a complex reaction process, including a solid phosphate, iron oxide, lithium salt, carbon precursor, and reducing gas phase. In this complicated reaction process, it is difficult to ensure the consistency of the reaction.
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.
