摘要
Abstract
The LMFP and NCM were mixed and used as the cathode active material,and the orthogo-nal experiment method was adopted to conduct the research on the cathode formula of the compound battery.Nine cathodes formulations of the orthogonal table were processed,it was found that due to the large specific surface area of LMFP,the homogenization process required an increased stirring in-tensity and longer stirring time.Moreover,the higher the content of LMFP,the lower the solid con-tent of the slurry,and the lower the maximum compaction density of the electrode sheet.60 cycle tests were conducted on nine types of soft-pack batteries.The results show that when the LMFP∶NCM in the cathode formula is 2∶8,the PVDF addition amount is 2.5%,and the CNT addition amount is 1%,the battery had the best cycle performance.Samples of batteries were prepared using the best cathode formulation.The results show that when the specific energy is 240 Wh/kg,the com-posite battery is not suitable for high-rate discharging above 3 C.After 500 cycles,the capacity reten-tion rate of the battery is 90.12%,the battery demonstrates excellent cycling performance.关键词
