    • 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.
    • 本文公开了制造电池电极系统的方法。 在该方法的一个实例中,聚合物粘合剂,活性材料和导电填料的混合物沉积在集电器上。 将沉积的混合物暴露于具有与集电体的表面垂直的场方向的外部场。 曝光从集电器表面向外平行,活性材料和导电填料对齐,以形成从集电器的表面向外延伸并垂直于集电器表面的多个离散结构,并分别与一个场 外场的线。 多个离散结构中的每一个包括一些活性材料和一些导电填料。
