Аннотация:The influence of different conductive additives (carbon nanofibers (CNFs), carbonnanoplatelets, and pyrolytic carbon from sucrose (Sucr) or polyvinylidene fluoride) on the morphology, electron conductivity, and electrochemical performance of LiFePO4-based cathodes wasinvestigated to develop the most efficient strategy for the fabrication of high-rate cathodes. Pyrolyticcarbon effectively prevents the growth of LiFePO4 grains and provides contact between them, CNFsprovide fast long-range conductive pathways, while carbon nanoplatelets can be embedded in carboncoatings as high-conductive “points” which enhance the rate capability and decrease the capacityfading of LFP. The LiFePO4/CSucr/CNF showed better performance than the other cathodes due tothe synergy of the high-conductive CNF network (the electronic conductivity was 1.3 × 10−2 S/cm)and the shorter Li+ion path (the lithium-ion diffusion coefficient was 2.1 × 10−11 cm2/s). It is shownthat the formation of composites based on LFP and carbon nanomaterials via mortar grinding is amore promising strategy for electrode material manufacturing than ball milling.
