Negative electrode active material and electrochemical device

A film capacitor includes a capacitor element that includes an element body formed of a winding of or a laminate of metallized films and a P pole electrode and an N pole electrode that are respectively formed on opposite end faces of the element body. The film capacitor also includes a P electrode bus bar and an N electrode bus bar that are respectively connected to the P pole electrode and the N pole electrode, and an electrically conductive covering that covers a peripheral surface of the capacitor element with the covering spaced away from at least one of the P pole electrode or the N pole electrode.

Film capacitor

A film capacitor according to the present disclosure includes: a film capacitor element; a bus bar connected to the film capacitor element; and an exterior member which covers the film capacitor element and the bus bar; wherein the exterior member is formed of a metal laminate film, the metal laminate film having a first resin layer on a surface facing the film capacitor element, a part of the bus bar is exposed to an outside of the exterior member, and a second resin layer containing an acid-modified resin is formed between the first resin layer and the bus bar at an exposing port of the exterior member through which the part of the bus bar is exposed from the exterior member.

Film capacitor and manufacturing method therefor

A metallized film capacitor includes first and second winding cores disposed along a center axis, and a capacitor element wound about the center axis around the first and the second winding cores. The second winding core is apart from the first winding core. The first and second winding cores have a thermal conductivity larger than that of the dielectric film of the capacitor element. Length Lof the capacitor element in a direction of the center axis, length Lof the first winding core inside the capacitor element in the direction of the center axis, and length Lof the second winding core inside the capacitor element in the direction of the center axis satisfy the relations of L&#x3e;L, L+L&#x3c;L, L&#x2267;L/2, and L&#x2267;(L&#x2212;L)/2. The metallized film capacitor provides the capacitor element with improved heat dissipation performance.
