The Optimum Nanomicro Structure of LiFePO₄/Ortho-Rich Polyacene Composites

An optimum nanomicro structure of LiFePO 4 / o -polyacene (LiFePO 4 /O-PAS) with a high proportion of ortho linkages has been constructed using special processing technologies. O-PAS produces a thin, uniform conductive network because of its unique structure with low-branching and long-range order. The nanomicro structure of the composite cooperates with O-PAS to improve the electronic conductivity and lithium ion mobility, decrease the specific surface area, and improve the quality of the prepared electrode, which are the key factors for the large scale manufacture of lithium iron phosphate materials.
