A multiply-conductive matrix (MCM) for a current collector/electrode and a method of making the MCM are disclosed. The MCM includes a frame, preferably including a lug, the frame preferably made from a reticulated polymer foam substrate, and a body preferably made from the same substrate. The specific surface area of the frame is greater than the specific surface area of the body, resulting in greater rigidity and strength of the frame when the body and frame are joined to form an assembled matrix. Electrically conductive material is applied to the matrix to form the current collector. Optionally, a bonding material is also applied. Electro-active paste is applied to current if collector. The resulting MCM-based electrodes are ultra light and may be used as anode or cathodes in a lead-based battery, lithium ion battery, and nickel metal hydride battery for improved performance.

摘要:
The invention comprises an improved cadmium negative electrode which is less prone to fading, can easily be manufactured by a pasting technique, and which does not require any external cycling to develop a precharge. This is accomplished by the use of irregular knarled cylindroidal cadmium particles of an average size ranging from 8 to 25 microns as measured by a Fisher Subsieve Sizer. The irregular knarled cylindroidal shape of the particles provides a substantial improvement pyrophoric characteristics while stilll providing electrochemical activity within a nickel-cadmium cell.
