论文摘要
多孔金属结构经常用于电化学能源存储设备，作为支撑，当前的收集器或活性电极材料。例如，散装金属孔隙化，焊接，焊接或化学合成途径涉及晶体生长或自组装，有时可以提供有限的多孔长度尺度，订购，周期性，可重复性，孔隙率和表面积的有限控制。添加剂制造和3D打印表明有可能彻底改变建筑金属的制造多种形式，从而使复杂的几何形式通常不可能通过传统的方法不可能，但是可以利用基于所需的物理或化学特性的多孔金属的完整设计自由。我们讨论了EES设备中多孔金属结构的属性，并就架构金属如何减轻电化学活跃的多孔金属电流收集器的问题提供了一些意见，并为电池，超级电容器或其他电化学设备所需的电化学特性提供了基于电化学特性的最佳设计的机会。
Porous metallic structures are regularly used in electrochemical energy storage devices as supports, current collectors or active electrode materials. Bulk metal porosification, dealloying, welding or chemical synthesis routes involving crystal growth or self-assembly for example, can sometimes provide limited control of porous length scale, ordering, periodicity, reproducibility, porosity and surface area. Additive manufacturing and 3D printing has shown the potential to revolutionize the fabrication of architected metals many forms, allowing complex geometries not usually possible by traditional methods, but enabling complete design freedom of a porous metal based on the required physical or chemical property to be exploited. We discuss properties of porous metal structures in EES devices and provide some opinions on how architected metals may alleviate issues with electrochemically active porous metal current collectors, and provide opportunities for optimum design based on electrochemical characteristics required by batteries, supercapacitors or other electrochemical devices.
