Binders play an important role in electrode processing for energy storage systems. While conventional binders often require hazardous and costly organic solvents, there has been increasing development toward greener and less expensive binders, with a focus on those that can be processed in aqueous conditions. Due to their functional groups, many of these aqueous binders offer further beneficial properties, such as higher adhesion to withstand the large volume changes of several high-capacity electrode materials. In this review, we first discuss the roles of binders in the construction of electrodes, particularly for energy storage systems, summarize typical binder characterization techniques, and then highlight the recent advances on aqueous binder systems, aiming to provide a stepping stone for the development of polymer binders with better sustainability and improved functionalities.
粘结剂在储能系统的电极加工中起着重要作用。虽然传统粘结剂通常需要危险且昂贵的有机溶剂，但目前越来越倾向于开发更环保、成本更低的粘结剂，重点是那些可在水性条件下加工的粘结剂。由于其官能团，许多这类水性粘结剂还具有其他有益特性，例如具有更高的附着力，能够承受几种高容量电极材料的大幅体积变化。在本综述中，我们首先讨论粘结剂在电极构建中的作用，特别是在储能系统中，总结典型的粘结剂表征技术，然后重点介绍水性粘结剂体系的最新进展，旨在为开发具有更好可持续性和改进功能的聚合物粘结剂提供一个基础。
