。Although it is not possible to explain in detail the reason why polymeric substances having conjugated double bonds were selected in the present invention, it is assumed that the reason is as follows. Namely, these substances are different from ordinary activated carbon. It is a homogeneous compound with fewer impurities than other materials.The presence of conjugated double bonds facilitates the progression of graphite and reaches a sieving electrical conductivity.

い。Furthermore, in the present invention, firing consists of two processes: carbonization and activation. Carbonization is carried out at a temperature range of 200-1500°C for 1-50 hours, preferably in an inert gas atmosphere or in a true wall for 2-24 hours at a temperature range of 300-800°C. In this case, it is particularly preferable to preheat for a certain period of time at a temperature lower than the desired temperature, that is, usually 200 to 300° C., and then gradually heat it to set the desired temperature.
