Abstract

The invention discloses a bipolar battery board, which is used to manufacture bipolar batteries. A bipolar battery plate (10) includes a frame (11), a substrate (12), first and second lead layers (14, 14), and positive and negative active materials (16, 18). The substrate comprises an insulating plastic having uniformly dispersed throughout the insulating plastic and conductive particles exposed along the surface of the substrate, said substrate (12) being positioned within said frame (11). A first lead layer is positioned on one side of the substrate and a second lead layer is positioned on the other side of the substrate. The first and second lead layers are electrically connected to each passing conductive particle. A positive active material is positioned on a surface of the first lead layer and a negative active material is positioned on one surface of the second lead layer.

Description

technical field [0001] The present invention relates to a battery, and more particularly to a bipolar battery having a series of bipolar battery plates. Background technique [0002] Conventional bipolar batteries generally include electrodes having a metallic conductive substrate on which a positive active material forms one surface and a negative active material forms the opposite surface. The active material is held by various means on a metallic conductive substrate that is not conductive to electrolyte ions. The electrodes are arranged in parallel stacked relationship to provide a multi-cell battery having an electrolyte and a spacer that provide an interface between adjacent electrodes. Conventional monopolar electrodes used at the ends of the stack are electrically connected to the output terminals. Most bipolar batteries developed to date have used metal substrates. In particular, bipolar lead-acid systems have utilized lead and lead alloys for this purpose. The ...
