摘要

Stable nitroxyl radical polymers, such as poly (2,2,6,6-tetramethyl-l-piperidinyloxy-4-yl methacrylate) (PTMA), are known to be effective as cathode active materials for lithium rechargeable batteries and are attracted as a replacement for transition-metal oxides. Lithium half cells were fabricated using PTMA-carbon composite electrodes. Then their capacity, cycling stability and rate capability were measured in detail. This enabled us to obtain specific capacities almost equal to the theoretical value (ill mAh g~(-1)). A 100-mAh class of aluminum-laminated film packaged battery with a PTMA-carbon composite cathode and a graphite anode has been fabricated. Because PTMA comprised only 6.2 % of the total cell weight, the energy density was considerably less than that of a lithium ion battery. However, the power density per active material weight was found to be better than that of lithium ion battery. The applications which require high-power capability rather than high-energy density, such as the sub-battery in electronic devices and motor drive assistance in electric vehicles, would be appropriate for organic radical batteries in the future.
