METHODS FOR MAKING BATTERY ELECTRODE SYSTEMS |
摘要 |
Methods for making battery electrode system are disclosed herein. In an example of the method, a mixture of a polymer binder, an active material and a conductive filler is deposited on a current collector. The deposited mixture is exposed to an external field having a field direction that is normal to a surface of the current collector. The exposure aligns, outward from and normal to the surface of the current collector, the active material and the conductive filler to form a plurality of discrete structures that extend outward from and normal to the surface of the current collector and are respectively aligned with a field line of the external field. Each of the plurality of discrete structures includes some of the active material and some of the conductive filler.
