CARBONIZED BIOPOLYMERS

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.
