The methods to improve the electrochemical performance of lithium iron phosphate are presented in detail. 1. Introduction Battery technology is a core technology for all future generation clean energy vehicles such as fuel cell vehicles, electric vehicles and plug-in hybrid vehicles.
Since its first introduction by Goodenough and co-workers, lithium iron phosphate (LiFePO 4, LFP) became one of the most relevant cathode materials for Li-ion batteries and is also a promising candidate for future all solid-state lithium metal batteries.
To investigate the cycle life capabilities of lithium iron phosphate based battery cells during fast charging, cycle life tests have been carried out at different constant charge current rates. The experimental analysis indicates that the cycle life of the battery degrades the more the charge current rate increases.
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.
Lithium iron phosphate cathode materials containing different low concentration ion dopants (Mg 2+, Al 3+, Zr 4+, and Nb 5+) are prepared by a solid state reaction method in an inert atmosphere. The effects of the doping ions on the properties of as synthesized cathode materials are investigated.
The layered structure of graphite and its high electronic conductivity are favourable for ensuring high efficiency of ionic–electronic processes in the graphite electrode. To achieve significant improvement in Li-ion battery parameters, the approach is to improve and upgrade the cathode materials.
