论文摘要
可穿戴的电子设备和小工具增加了对柔性，薄和轻质电池的需求。在本文中，我们首次提出了一种独特的单步方法，用于制备用于弹性 - 触发应用程序的膜 - 电极组件。商用纳米孔膜相对侧的正电池电极（LFP和LTO）的并发电泳沉积（EPD）（CELGARD 2325）导致形成了三层板块结构。包含该电泳沉积结构的细胞以125-140mAh/g的容量进行了150多个循环，该循环接近磷酸锂的理论值。电极可以通过更换可互换的充电剂（如聚乙烯和聚丙烯酸）来沉积阴极或阳极。当吸附在活性材料的颗粒上时，这些聚电解质也用作粘合剂。我们开发的同时EPD可用于纳米孔聚合物和陶瓷离子传导膜上的各种阴极和阳极材料的简单和低成本制造，用于储能设备。
Wearable electronic devices and gadgets raise the need for flexible, thin and lightweight batteries. In this article we present for the first time, a unique, single-step method for the preparation of a membrane-electrode assembly for flexible-batteries application. Concurrent electrophoretic deposition (EPD) of positive and negative battery electrodes (LFP and LTO) on opposite sides of a commercial nanoporous membrane (Celgard 2325) results in the formation of a three-layer-battery structure. The cell comprising this electrophoretically deposited structure ran for more than 150 cycles with 125-140mAh/g capacity, which approaches the theoretical value of lithium iron phosphate. The electrodes can be deposited either cathodically or anodically by replacing the interchangeable charging agents, like polyethyleneimine and polyacrylic acid. These polyelectrolytes, when adsorbed on the particles of the active material, serve also as the binders. The simultaneous EPD, which we developed, can be used for the simple and low-cost manufacturing of a variety of cathode and anode materials on nanoporous polymer- and ceramic ion-conducting membranes for energy storage devices.
