Abstract:
A power storage device positive electrode having an excellent activation property from the initial charge/discharge stage, and a power storage device employing the positive electrode are provided. The power storage device positive electrode includes an active material including at least one of polyaniline and a polyaniline derivative, a conductive agent, and a binder, wherein the active material including at least one of the polyaniline and the polyaniline derivative has a polyaniline oxidant proportion of not less than 45 wt. % based on the overall weight of the polyaniline active material, wherein the binder has Hansen solubility parameters such that the sum of a polarity term and a hydrogen bonding term is not greater than 20 MPa1/2.
Abstract:
Provided is a container for use in a stirring device, the container including: an inner tubular portion (41) having a bottom and formed to have a cylindrically-shaped inner circumferential surface, the inner tubular portion capable of containing therein a material (11) for preparing an epoxy resin composition containing an epoxy resin, a curing agent, and a porogen; and a shaft portion (42) having a tubular or columnar shape and placed upright on a central region of an inner side of the bottom of the inner tubular portion (41). Further provided are a stirring device using the container and a method for producing a separator for nonaqueous electrolyte electricity storage devices.
