摘要:
A non-activated, majority non-graphitic amorphous carbon material may be produced by supplying a carbonized precursor material, heating the carbonized precursor material in a first heating step at a temperature and for a duration sufficient to produce a heat-treated carbon material that has a specific surface area less than about 500 m2/g and is less than about 20% graphitic by mass, purifying the heat-treated carbon material, and heating the purified heat-treated carbon material in a second heating step at a temperature and for a duration to produce a non-activated, majority non-graphitic amorphous carbon material that has a specific surface area less than about 500 m2/g and is less than about 20% graphitic by mass.
