摘要： Porous electrodes in which the porosity has a low tortuosity are generally provided. In some embodiments, the porous electrodes can be designed to be filled with electrolyte and used in batteries, and can include low tortuosity in the primary direction of ion transport during charge and discharge of the battery. In some embodiments, the electrodes can have a high volume fraction of electrode active material (i.e., low porosity). The attributes outlined above can allow the electrodes to be fabricated with a higher energy density, higher capacity per unit area of electrode (mAh/cm2), and greater thickness than comparable electrodes while still providing high utilization of the active material in the battery during use. Accordingly, the electrodes can be used to produce batteries with high energy densities, high power, or both compared to batteries using electrodes of conventional design with relatively highly tortuous pores.

摘要翻译： 通常提供多孔电极，其中孔隙度具有低弯曲度。 在一些实施例中，多孔电极可被设计为填充电解质并用于电池中，并且可以包括在电池充电和放电期间离子传输的主要方向上的低弯曲度。 在一些实施例中，电极可以具有高体积分数的电极活性材料（即，低孔隙率）。 上述属性可以允许电极以比同类电极更高的能量密度，每单位面积电极的容量（mAh / cm 2）和更大的厚度制造，同时仍然在使用期间提供电池中活性材料的高利用率 。 因此，与使用具有相对高曲率孔的常规设计的电极的电池相比，电极可用于生产具有高能量密度，高功率或两者的电池。
