Abstract
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.

A bipolar battery plate for a bipolar battery, comprising:
- a frame having a substrate receiving passageway positioned in the middle thereof and a pair of material receiving passageways positioned on opposite sides of the substrate receiving passageway;
- a substrate positioned within the frame and extending into and secured within the substrate receiving passageway, the substrate having insulative plastic with conductive particles homogeneously dispersed throughout the insulative plastic and exposed along a surface of the substrate;
- a first lead layer positioned within a first passageway of the pair of material receiving passageways, the first lead layer entirely covering one exposed side of the substrate;
- a second lead layer positioned within a second passageway of the pair of material receiving passageways, the second lead layer entirely covering another exposed side of the substrate, the first and second lead layer electrically connected to each other through the conductive particles;
- a positive active material positioned within the first passageway, the positive active material layered over an outer surface of the first lead layer;
- and
- a negative active material positioned within the second passageway, the negative active material layered over an outer surface of the second lead layer.
A bipolar battery, comprising
- a plurality of plates positioned next to each other, each plate having,
- a frame having a substrate receiving passageway positioned in the middle thereof and a pair of material receiving passageways positioned on opposite sides of the substrate receiving passageway;
- a substrate positioned within the frame and extending into and secured within the substrate receiving passageway, the substrate having insulative plastic with conductive particles homogeneously dispersed throughout the insulative plastic and exposed along a surface of the substrate;
- a first lead layer positioned within a first passageway of the pair of material receiving passageways, the first lead layer entirely covering one exposed side of the substrate;
- a second lead layer positioned within a second passageway of the pair of material receiving passageways, the second lead layer entirely covering another exposed side of the substrate, the first and second lead layer electrically connected to each other through the conductive particles;
- a positive active material positioned within the first passageway, the positive active material layered over an outer surface of the first lead layer;
- and
- a negative active material positioned within the second passageway, the negative active material layered over an outer surface of the second lead layer;
- a pair of terminal sections positioned on opposite ends of the stacked plurality of bipolar plates;
- and
- an electrolyte positioned between each of the plurality of bipolar plates such that the electrolyte extends into the first passageway and the second passageway of adjacent frames of the plurality of bipolar plates.
