Abstract
A conductive film includes a conductive filler having a spike-shaped form or a structure-shaped form and a resin binder, in which the conductive filler has a ratio of a BET specific surface area to an equivalent sphere surface area based on a D50 of the conductive filler as 5.0 or more and 10 or less, and the conductive filler is contained in an amount of more than 3.0% by mass and less than 20% by mass with respect to a total mass of the resin binder and the conductive filler.
Claims6
A conductive film comprising:
- a conductive filler having a spike-shaped form or a structure-shaped form;
- and
- a resin binder, wherein:
- the conductive filler has a ratio of 5.0 or more and 10 or less as a ratio of a BET specific surface area to an equivalent sphere surface area based on D50 of the conductive filler;
- and
- the conductive filler is contained in an amount of more than 3.0% by mass and less than 20% by mass with respect to a total mass of the resin binder and the conductive filler.
A collector for a bipolar secondary battery, the collector comprising a conductive resin layer including
- a conductive filler having a spike-shaped form or a structure-shaped form, and
- a resin binder, wherein:
- the conductive filler has a ratio of 5.0 or more and 10 or less as a ratio of a BET specific surface area to an equivalent sphere surface area based on D50 of the conductive filler, and
- the conductive filler is contained in an amount of more than 3.0% by mass and less than 20% by mass with respect to a total mass of the resin binder and the conductive filler.
