Estimating the term…
Electrodes including bipolar composite electrodes and end electrodes are characterized by a layer of electrochemically active material bonded to a first surface of a non-conductive electrode substrate material. In the case of a bipolar electrode, the opposing second surface of the substrate material also carries a layer of electrically active material, the layer of electrochemically active material contacting through said substrate material to provide a current pathway. In the case of an end electrode, the opposing second surface of the substrate material carries a layer of electrically active material, the layer of electrochemically active material contacting the layer of electrically active material through the substrate material to provide a current pathway. Processes of preparing the electrodes and uses of the electrodes in batteries are also disclosed.
An electrode including a layer of non-conductive electrode substrate material having a first surface and an opposing second surface, one of said first and second surfaces carrying a first layer of electrochemically active material, the other of said surfaces carrying a second layer of either electrochemically active material or electrically conductive material and wherein said first and second layers contact so as to provide a current transfer pathway through said substrate material.
A process for manufacturing an electrode, said process including forming an assembly comprising a layer of non-conductive plastic electrode substrate material between either a first and opposing second layer of electrochemically active material, or a first layer of electrochemically active material and an opposing second layer of electrically conductive material and applying heat and pressure to said assembly such that the first and second layers are caused to contact so as to provide a current transfer pathway through said polymeric substrate material.
A process for manufacturing a bipolar electrode, said process including forming an assembly comprising a layer of non-conductive plastic electrode substrate material between two opposing layers of electrochemically active material, and applying heat and pressure to said assembly such that the opposing layers of electrochemically active material are caused to penetrate through said substrate material such that they contact to provide a current transfer pathway.
A process for manufacturing an end electrode, said process including forming an assembly comprising a layer of non-conductive plastic electrode substrate material between a first layer of electrochemically active material and an opposing second layer of electrically conductive material, and applying heat and pressure to said assembly, such that the layer of electrochemically active material is caused to penetrate through said polymeric substrate material and contact said layer of electrically conductive material to provide a current transfer pathway through said plastic substrate material.
