本综述首先简单介绍了扫描电化学显微镜的基本概况，尤其是不同的工作模式. 其次，有针对性地介绍了SECM的不同工作模式在氧还原和水解析氧反应相关研究中的应用. 最后，对扫描电化学显微镜未来在新能源转换存储系统研究领域的应用进行了展望.

Scanning electrochemical microscopy (SECM) has been proved to be a unique technique for combinatorial screening of localized phenomena for different electrocatalysts potentially used in new energy conversion and storage systems. This mini-review provides a brief summary of different SECM working modes, such as direct mode, feedback mode, generation-collection mode, redox competition mode and noise mode, which are especially applied for characterizing the oxygen reactions. Particularly, a series of important development in SECM screening of electrocatalysts for oxygen reduction reaction and oxygen evolution reaction from the author and W. Schuhmann’s group in Germany has been highlighted and overviewed. Finally, some prospects for the SECM development in new energy system-related research in the future are also discussed.
