| description | The invention provides an activated carbon microsphere with a high specific surface area and a manufacturing method thereof, an electrode slice and a capacitor. The manufacturing method includes the steps of: providing an mesocarbon microbead which includes gamma-resin; performing a drying step in which the mesocarbon microbead is heated for 8 to 12 hours with a temperature of 410 to 550 DEG C; performing an activation step on the mesocarbon microbead which goes through the drying step so as to form an activated carbon microsphere, wherein the content of the gamma-resin in the mesocarbon microbead is below 0.5 percentage by weight. The activated carbon microsphere with the high specific surface area is obtained by the manufacturing method. The electrode slice includes the activated carbon microsphere with the high specific surface area. The capacitor includes the electrode slice. The manufacturing method removes the gamma-resin of the mesocarbon microbead via the drying step, thereby reducing the usage amount of an activating agent, and the activated carbon microsphere that is obtained has a high specific surface area and a high specific capacitance value, and can be applied to the electrode slice and the capacitor. |
