First, the present invention involves adding a curing catalyst to a phenolic resin, polyvinyl alcohol, a pore-forming agent, and a cross-linking agent, and mixing, casting, heating, and drying the same. Next, the plate-shaped porous phenolic resin obtained thereby which has uniform consecutive macropores having an average pore diameter in the range of 3 to 35 &#x3bc;m and formed in a three-dimensional network pattern is immersed with an organic solvent. Thereafter, this block is extracted and pressure is applied thereto. It is possible to obtain plate-shaped activated carbon for use in an electrode of a power-storage device by carbonizing and activating a block which has undergone this procedure by keeping the same at an increased temperature.

Activated carbon for use in electrode of power-storage device, and method for producing same

An activated carbon for an electrode of a power storage device of the present invention has uniform consecutive macropores, and a pore size distribution centered within a range of 1.5 to 25 &#x3bc;m, a specific surface area within a range of 1,500 to 2,300 m/g, a micropore volume within a range of 0.4 to 1.0 mL/g, and an average micropore width within a range of 0.7 to 1.2 nm. Provided is an activated carbon for an electrode of a power storage device suitable for an electric double layer capacitor that has high capacitance during charging and discharging at high current density and excellent endurance against charging at a high voltage of 3 V or more and a lithium-ion capacitor having excellent endurance against charging at a high voltage of 4 V or more.

A filter container includes a sheet having a base with a liquid inlet pipe and a liquid exhaust pipe and a cap that is integrally attached to the base. A disposable unit container is housed inside the sheet, and the disposable unit container contains cartridge filters. The disposable unit container has a liquid inlet port and a liquid outlet port at a bottom portion thereof, these ports being provided with shut-off valves on the inside of the disposable unit container. The shut-off valves are engagable by the inlet and exhaust pipes on the base of the sheet so that the valves are open by engaging the disposable unit container with the base with the sheet, and are closed by removing the unit container from the base. The bottom end cap supports the lower ends of the cartridge filters above the inlet and outlet ports, and defines the inlet and outlet liquid flow paths. Upper end caps are also provided for sealing the upper ends of the cartridge filters.
