| Research Abstract |
Porous resin-based microspheres were prepared from the mixture of pyrene-based thermosetting resin and polyethylene glycol in a presence of acid catalyst by heating and stirring. The low polymerization degree of the resin was much important and then the particle size of the microspheres were 1-2 micrometer. The microspheres seemed to be the aggregates with open cleft on the surfaces. The carbon microspheres heat-treated at 1000 to 2500 degree C were evaluated as anode materials for batteries, compared with the results of graphite. Specific discharge capacities of graphite anode rapidly decreased down to 10 % at 100 to 2000 mA/g as a current density. On the other hand, those of carbon sphere anodes decreased only down to 47 %. These results suggest that those carbon spheres have several possibilities such as rapid charging and high discharge capacitance.
