Electrochemical capacitor, carbonized biopolymers and carbonization process |
摘要 |
A carbon material suitable for the preparation of electrodes for electrochemical capacitors is obtained by single-stage carbonization of biopolymers with a large content of heteroatoms. Neither addition of an activating agent during carbonization nor subsequent gas phase activation is necessary. Several biopolymers which are available by extraction from seaweed are suitable precursors. Alternatively, the seaweed containing such biopolymers is carbonized directly.
