A novel core/shell compound has been developed by coating a spherical LiFePO 4 structure with a specific π‐bond character planar polymer (polyacene, PAS). The electronic conductivity, low‐temperature character, and tap density of the LiFePO 4 –PAS composite were significantly improved compared to LiFePO 4 , which may lead to use in lithium‐ion battery applications.
