The lithium iron phosphate battery (LiFePO 4 battery) or LFP battery (lithium ferrophosphate) is a type of lithium-ion battery using lithium iron phosphate (LiFePO 4) as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode.
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.
Negative electrodes (anode, on discharge) made of petroleum coke were used in early lithium-ion batteries; later types used natural or synthetic graphite. 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.
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).
Top balancing is by far the most common process used for building a lithium battery bank, because cell imbalance issues at the low end normally never become apparent, on the basis that cycling that deep doesn’t normally happen; at this point, the bank hardly has any stored energy left and cutting it out becomes a simple and logical response.
Challenges: With the availability of different electrochemical materials, the lithium based battery system can be designed to a specifical application regarding voltage level, SOC, lifetime, and safety. The electrochemical couples can also be used to design batteries as per the available energy.
Shaking it loose over time could turn the battery into a fire risk. A lithium battery bank should be installed aft of midships typically, in the most comfortable part of the vessel and the cells must be firmly clamped as discussed earlier.
