摘要： Systems and methods for anisotropic expansion of silicon-dominant anodes may include a cathode, an electrolyte, and an anode, where the anode may include a current collector and an active material on the current collector. An expansion of the anode during operation may be configured by a roughness and/or thickness of the current collector, a metal used for the current collector, and/or a lamination process that adheres the active material to the current collector. The expansion of the anode may be more anisotropic for thicker current collectors. A thicker current collector may be 10 μm thick or greater. The expansion of the anode may be more anisotropic for more rigid materials used for the current collector. A more rigid current collector may include nickel and a less rigid current collector may include copper. The expansion of the anode may be more anisotropic for a rougher surface current collector.

摘要： 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.
