To address long-term capacity degradation resulting from cALL, we propose a lithium replen-ishment strategy designed to enhance the cycling performance of lithium-ion batteries (LIBs) throughout their entire lifecycle.
Our innovative long-term lithium replenishment method ensures a sustained and controlled release of lithium ions throughout the battery's lifespan, effectively mitigating both the capacity loss arising from iALL and the capacity degradation associated with cALL, thus significantly extending the cycle life of LIBs.
Several methods of lithium polymer lithium battery replenishment The common pre-lithiation method is to supplement the negative electrode with lithium, such as lithium foil supplemented with lithium, lithium powder supplemented with lithium, etc., which are all pre-lithiation processes that are currently being developed.
A persistent challenge plaguing lithium-ion batteries (LIBs) is the consumption of active lithium with the formation of SEI. This leads to an irreversible lithium loss in the initial cycle and a gradual further exhaustion of active lithium in subsequent cycles. While prelithiation has been proven effective i Recent Open Access Articles
Upon thorough analysis, the mechanism of lithium replenishment can be delineated as follows: FePO 4 concurrently undergoes electron acquisition and Li + incorporation, facilitating its conversion into LiFePO 4 as depicted in Equation (1).
The cycling performance of the pouch cell at 0.5C is shown in Fig. 4g. After 500 cycles, the cell maintains a discharge capacity of 130.2 mA h g −1, with a high capacity retention of 90.49%. These results indicate the promising potential of our lithium replenishment method for energy storage applications.
