摘要
Abstract
To enhance electrochemical performance,LiFePO4(LFP)was composited with carbon aero-gel(CA),leveraging its high specific surface area and porous structure.This work specifically investi-gates the effects of two key physical properties—LFP particle size and CA's specific surface area—on the composite's performance.Experiments demonstrate that the composite electrode constructed with small-sized LFP and high-specific-surface-area CA exhibits excellent comprehensive perfor-mance,delivering an initial discharge specific capacity of up to 165.5 mAh/g with an initial Coulom-bic efficiency of 100.0%,and maintaining a high capacity retention rate of 94.6%after 500 cycles.This result clearly verifies the significant impact of raw materials'physical properties on the electro-chemical performance of the composite and provides an important optimization basis for the subse-quent design of high-performance LFP/CA composite electrodes.关键词
