Abstract
The disclosure is directed to a bipolar battery that is constructed to improve battery performance by reducing distortions within electrode material of the bipolar battery. The bipolar battery includes multiple battery elements that each includes multiple unit batteries. Each unit battery contains a conductor having a positive electrode layer and a negative electrode layer. A collector is positioned between adjacent positive and negative electrode layers of adjacent unit batteries, and an accumulated thickness absorption member is used to separate collectors of adjacent battery elements. The bipolar battery may be used in a motor vehicle, such as an electric car.
