Estimating the term…
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.
A porous electrically conductive carbon material including graphene stacks and having first and second pores in first and second different pore size ranges respectively, wherein said first pores are of irregular shape in three dimensions, are interconnected to form transport passages through said carbon material and have sizes in the size range from 10 μm to 100 nm, wherein said second pores are defined between neighbouring graphene stacks, are of irregular shape in three dimensions, are interconnected, communicate directly or indirectly via other second pores with said first pores and have sizes in the size range from less than 100 nm to 3 nm and wherein said graphene stacks defining said second pores form wall material between said first pores.
