摘要： A wound non-aqueous electrolyte battery includes a positive electrode, a negative electrode, a separator provided between the positive and negative electrodes, and a non-aqueous electrolyte. The negative electrode includes a lithium-aluminum alloy sheet. The lithium-aluminum alloy sheet has surfaces including a surface of which parts are flush and connected with one another via grain boundaries of lithium-aluminum alloy. An average grain boundary number N is 8.75 or less, the average grain boundary number N being provided as ΣGi/ΣLi by dividing ΣGi by ΣLi, where ΣGi is a sum of numbers of grain boundaries Gi out of the plurality of grain boundaries which intersect M line segments PQi respectively connecting point Pi to point Qi on the surface of the lithium-aluminum alloy sheet, ΣLi is a sum of lengths Li of the M line segments PQi, M is an integer greater than 1, and i is an integer satisfying 1

摘要： An electrolytic capacitor includes an anode body, a dielectric layer formed on the anode body, a first conductive polymer layer covering at least a part of the dielectric layer, and a second conductive polymer layer covering at least a part of the first conductive polymer layer. The first conductive polymer layer includes a first conductive polymer. The second conductive polymer layer includes a second conductive polymer. The first conductive polymer layer and the second conductive polymer layer each further include a first polymer dopant having a sulfonation degree of S1. At least one of the first conductive polymer layer and the second conductive polymer layer further includes a second polymer dopant having a sulfonation degree of S2. The sulfonation degree of S1 and the sulfonation degree of S2 satisfy a relation of S1

摘要： An electrolytic capacitor includes an anode body having a dielectric layer, a first conductive polymer layer covering at least a part of the dielectric layer, and a second conductive polymer layer covering at least a part of the first conductive polymer layer. The first conductive polymer layer includes a first conductive polymer and a first polymer dopant having a sulfonate group. The second conductive polymer layer includes a second conductive polymer and a second polymer dopant having a sulfonate group. A polymerization degree of the first conductive polymer is lower than a polymerization degree of the second conductive polymer.
