Optimized LiFePO4-Polyacene Cathode Material for Lithium-Ion Batteries

Optimized LiFePO4-Polyacene Cathode Material for Lithium-Ion Batteries

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 LiFeP...

Zusammenfassung: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.
