4. Conclusion
In conclusion, the pre-lithiation method could effectively enhance the battery performance compared to CM. In particular, the EM4C sample shows the highest battery performance with the discharged capacity of 137.06 and 97.87 mAh.g-1 in the first and 80th cycle, while the CM30 demonstrates a capacity of 71.40 mAh.g-1 in the 80th cycle, respectively. In addition, the EM4C exhibits remarkable cycling performance, with a retention capacity of 71.4% after 80 cycles at a C/3 current density compared to the other samples. The remarkable improvement in the performance of SiO2/C||NMC622 full-cell using the EM technique can be attributed to a stable artificial SEI layer on the anode surface which enhance the mobility of Li+ ions and remained enough Li+ ions stored capacity for stabilizing the SEI layer. Therefore, the EM is a promising pre-lithiation method for the silicon or silicon-based anode material to enhance battery performance in LIB applications.
