ELECTROCHEMICAL HIGH RATE STORAGE MATERIALS PROCESS AND ELECTRODES

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 m/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 m/g and is less than about 20% graphitic by mass.
