4. Conclusion Lithium iron phosphate batteries were aged in two ways, by holding at a high potential corresponding to 100% SOC and cycling at 1C/6D at elevated temperature. In both cases, differential thermal voltammetry (DTV) was capable of diagnosing degradation in a similar way to incremental capacity analysis (ICA).
Previously, DTV experiments have been carried out on nickel manganese cobalt oxide (NMC) cathode batteries and have not been tested on other battery chemistries. Lithium iron phosphate (LFP) is a commercially successful battery chemistry because of its high energy, power densities and stability in high temperature environments .
During the long charging/discharging process, the irreversible loss of active lithium inside the LFP battery leads to the degradation of the battery's performance. Researchers have developed several methods to achieve cathode material recovery from spent LFP batteries, such as hydrometallurgy, pyrometallurgy, and direct regeneration.
Despite many reports validating the conductivity of this electrolyte, it still suffers from passivating electrode degradation mechanisms. At first analysis, lithium iron phosphate (LFP) should be more thermodynamically stable in contact with sulfide electrolytes.
As can be seen in Fig. 4b, a significant charge capacity degradation was exhibited at plateau V as the cycling deepens. It indicates that the Li + deficiency inside the battery deepens, resulting in insufficient active Li + embedded in the graphite electrode in the charge .
At first analysis, lithium iron phosphate (LFP) should be more thermodynamically stable in contact with sulfide electrolytes. However, without substantial improvements to interfacial engineering, we find that LFP is not inherently stable against Li 6 PS 5 Br.
