摘要： In a bipolar storage battery where a positive electrode current collector plate and a negative electrode current collector plate are electrically connected in a through-hole of a substrate and a plurality of cell members are electrically connected in series, even when an electrolytic solution moves between the current collector plate and the substrate, the electrolytic solution is prevented from easily reaching the through-hole of the substrate, preventing a short circuit. At least one of a bottom surface of a recess that is a surface of a main substrate close to a positive electrode or a bottom surface of a recess that is a surface of the main substrate close to a negative electrode, the main substrate being a substrate arranged between cell members, has a ten-point average roughness (RzJIS) of between 30 μm and 104 μm, inclusive, and a maximum height roughness (Rz) of 123 μm or less.

摘要： An electrical storage device includes high surface area fibers (e.g., shaped fibers and/or microfibers) coated with carbon (graphite, expanded graphite, activated carbon, carbon black, carbon nanofibers, CNT, or graphite coated CNT), electrolyte, and/or electrode active material (e.g., lead oxide) in electrodes. The electrodes are used to form electrical storage devices such as electrochemical batteries, electrochemical double layer capacitors, and asymmetrical capacitors.

摘要： Apparatus and techniques herein related battery plates. For example, a first battery plate can include a conductive silicon wafer. A first mechanical support can be located on a first side of the conductive silicon wafer. A first active material can be adhered to the first mechanical support and the first side of the conductive silicon wafer, the first active material having a first polarity. In an example, the battery plate can be a bipolar plate, such as having a second mechanical support located on a second side of the conductive silicon wafer opposite the first side, and a second active material adhered to the second mechanical support and the second side of the conductive silicon wafer, the second material having an opposite second polarity.

摘要： A bipolar battery plate is utilized for production of a bipolar battery. The bipolar battery plate includes a frame, a substrate, first and second lead layers, and positive and negative active materials. The substrate includes insulative plastic with conductive particles homogeneously dispersed throughout the insulative plastic and exposed along surface of the substrate, the substrate positioned within the frame. The first lead layer is positioned on one side of the substrate, while the second lead layer is positioned on another side of the substrate. The first and second lead layer are electrically connected to each through the conductive particles. The positive active material is positioned on a surface of the first lead layer, and the negative active material positioned on a surface of the second lead layer.
