The exploitation and utilization of renewable clean energy is of great significance to the sustainable development of society. Electrokinetic energy conversion (EKEC) based on micro/nanochannels is expected to provide immense potential for ocean energy harvesting, self-powered micro/nanodevices, and small portable power supplies through converting environmental energy into electrical energy. Herein, aiming to get a deeper understanding of EKEC based on micro/nanochannels, several classic theoretical models and corresponding calculation equations are introduced briefly. For high efficiency energy conversion, it is essential to clearly discuss the interface properties between the inner surface of the channel and the bulk electrolyte solution. Therefore, we put forward soft interface designs of solid-liquid and liquid-liquid interfaces, and summarize their recent progress. In addition, the different applications of EKEC, harvesting from environmental energy, are further discussed. We hope that this review will attract more scientists' attention to transform the experimental results of EKEC systems in the lab into available products on shelves.
可再生清洁能源的开发和利用对社会的可持续发展具有重要意义。基于微纳通道的动电能量转换（EKEC）有望通过将环境能量转化为电能，为海洋能源采集、自供电微纳器件和小型便携式电源提供巨大潜力。在此，为了更深入地理解基于微纳通道的EKEC，简要介绍了几种经典理论模型及相应的计算公式。为实现高效能量转换，清晰讨论通道内表面与本体电解质溶液之间的界面性质至关重要。因此，我们提出了固液和液液界面的软界面设计，并总结了它们的最新进展。此外，还进一步讨论了EKEC从环境能量中采集能量的不同应用。我们希望这篇综述能吸引更多科学家的关注，将实验室中EKEC系统的实验成果转化为货架上的可用产品。
