A novel core/shell compound has been developed by coating a spherical LiFePO4 structure with a specific π-bond character planar polymer (polyacene, PAS). The electronic conductivity, low-temperature character, and tap density of the LiFePO4–PAS composite were significantly improved compared to LiFePO4, which may lead to use in lithium-ion battery applications.
