Claim 10:
11. A process of manufacturing microporous carbon material, comprising:
first and second consecutive stages;
the first stage including the step of passivation of a surface of at least one copolymer of poly(vinylidene chloride) by chemical attack in an alkaline alcohol solution that includes an alkali hydroxide dissolved in an alcohol, to cause formation of a surface-passivated copolymer having precarbonization on the surface;
the second stage including the step of pyrolysis of the surface-passivated copolymer to increase a surface area of the surface-passivated copolymer;
wherein the chemical attack is performed by reacting the at least one copolymer of poly(vinylidene chloride) with the alkali hydroxide dissolved in the alcohol.
