A conductive composition that can incorporate a space-saving safety device that safely cuts off a current when an electronic device abnormally generates heat without requiring a complicated process, and a battery that improves the charge / discharge characteristics of the battery A conductive composition for a current collector coat is provided. A conductive composition including a foamable substance and a conductive material that foams by heat, and imparts conductivity at a temperature lower than a predetermined temperature, but the foamable substance foams at a temperature higher than the predetermined temperature. Thus, a conductive composition that becomes insulating is provided. Further, the present invention is a conductive composition for coating a battery current collector that includes a substance having a hydrogen bondable functional group value of 1.0 to 5.0 × 10 −2 mol / g and a conductive material, and can be solidified and has fluidity. A battery current collector comprising a solid having a hydrogen bonding functional group value of 1.0 to 5.0 × 10 −2 mol / g in an amount of 50% by weight or more in a solid excluding the conductive material after solidification A conductive composition for a coat is provided. Furthermore, an electric circuit manufactured using the conductive composition and an electronic device including the electric circuit are provided. [Selection figure] None |
