Title
(EN) Porous Electrically Conductive Carbon Material And Uses Thereof
Abstract
(EN)

This disclosure relates to a porous electrically conductive carbon material having interconnected pores in first and second size ranges from 10 μm to 100 nm and from less than 100 nm to 3 nm and a graphene structure and to diverse uses of the material such as an electrode in a lithium-ion battery and a catalyst support, e.g. for the oxidation of methanol in a fuel cell. The carbon material has been heat treated to effect conversion to non-graphitic carbon with the required degree of order at a temperature in the range from 600° C. to 1000° C. A lithium-ion battery and an electrode for a lithium-ion battery are also claimed.
