能源存储和转换系统是新兴绿色技术的一个组成部分，包括移动电子设备、汽车、太阳能和风能经济的存储组件。尽管制造能力迅速扩大，宏观器件行为的现象学信息丰富，但支撑电池和燃料电池在纳米-微米范围内运行的微观机制实际上是未知的。这种信息的缺乏是由于缺乏能够在纳米尺度上解决涉及电池操作的基本机制的实验技术，包括电子和离子传输，空位注入和界面反应。本文简要概述了扫描探针显微镜（SPM）研究纳米级电化学功能的方法，并与宏观电化学方法进行了比较。讨论了新兴SPM方法的未来应用，包括近场光学、机电、微波和热探针以及联合SPM-(S)TEM（扫描透射电子显微镜）方法在储能和转换材料中的应用。
Energy storage and conversion systems are an integral component of emerging green technologies, including mobile electronic devices, automotive, and storage components of solar and wind energy economics. Despite the rapidly expanding manufacturing capabilities and wealth of phenomenological information on the macroscopic device behaviors, the microscopic mechanisms underpinning battery and fuel cell operations in the nanometer-micrometer range are virtually unknown. This lack of information is due to the dearth of experimental techniques capable of addressing elementary mechanisms involved in battery operation, including electronic and ion transport, vacancy injection, and interfacial reactions, on the nanometer scale. In this article, a brief overview of scanning probe microscopy (SPM) methods addressing nanoscale electrochemical functionalities is provided and compared with macroscopic electrochemical methods. Future applications of emergent SPM methods, including near field optical, electromechanical, microwave, and thermal probes and combined SPM-(S)TEM (scanning transmission electron microscopy) methods in energy storage and conversion materials are discussed.
