电化学储能装置的整体性能与表面和界面有着内在的联系。3D纳米阵列（3D- nas）作为一种极具发展前景的电极结构，具有相对有序、连续和完全暴露的单个纳米结构的活性表面，有利于电极内的质量和电子传递以及界面间的电荷转移，为工程提供了理想的平台。本文介绍了3D-NAs的表面和界面工程的关键概述，从电极和界面设计到器件集成。强调了3D-NA的一般优点和3D-NA混合电极的表面/界面工程原理。重点是使用3D-NAs作为一个优越的平台来调节界面性质，并在没有粘合剂干扰的情况下揭示新的机制/材料。还考虑了3D- nas表面的工程和利用，以开发具有三维集成电极/电解质界面或涉及其他活性物质的三维三相界面的柔性/固态eesd，这些界面具有（准）固态电解质渗透到整个器件中的特征。最后，概述了3D-NAs表面/界面工程的挑战和未来方向。提出了实现电极电荷平衡、优化多相固态界面和实现三维固体电解质渗透的潜在策略。
The overall performance of electrochemical energy storage devices (EESDs) is intrinsically correlated with surfaces and interfaces. As a promising electrode architecture, 3D nanoarrays (3D-NAs) possess relatively ordered, continuous, and fully exposed active surfaces of individual nanostructures, facilitating mass and electron transport within the electrode and charge transfer across interfaces and providing an ideal platform for engineering. Herein, a critical overview of the surface and interface engineering of 3D-NAs, from electrode and interface designs to device integration, is presented. The general merits of 3D-NAs and surface/interface engineering principles of 3D-NA hybrid electrodes are highlighted. The focus is on the use of 3D-NAs as a superior platform to regulate the interface nature and unveiling new mechanism/materials without the interference of binders. The engineering and utilization of the surface of 3D-NAs to develop flexible/solid-state EESDs with 3D integrated electrode/electrolyte interfaces, or 3D triphase interfaces involving other active species, which are characteristic of (quasi-)solid-state electrolyte infiltration into the entire device, are also considered. Finally, the challenges and future directions of surface/interface engineering of 3D-NAs are outlined. In particular, potential strategies to obtain electrode charge balance, optimize the multiphase solid-state interface, and attain 3D solid electrolyte infiltration are proposed.
