Long-life energy storage batteries are integral to energy storage systems and electric vehicles, with lithium-ion batteries (LIBs) currently being the preferred option for extended usage-life energy storage. To further extend the life span of LIBs, it is essential to intensify investments in battery design, manufacturing processes, and the advancement of ancillary materials. The pursuit of long durability introduces new challenges for battery energy density. The advent of electrode material offers effective support in enhancing the battery's long-duration performance. Often underestimated as part of the cathode composition, the binder plays a pivotal role in the longevity and electrochemical performance of the electrode. Maintaining the mechanical integrity of the electrode through judicious binder design is a fundamental requirement for achieving consistent long-life cycles and high energy density. This paper primarily concentrates on the commonly employed cathode systems in lithium-ion batteries, elucidates the significance of binders for both, discusses the application status, strengths, and weaknesses of novel binders, and ultimately puts forth corresponding optimization strategies. It underscores the critical function of binders in enhancing battery performance and advancing the sustainable development of lithium-ion batteries, aiming to offer fresh insights and perspectives for the design of high-performance LIBs.
长寿命储能电池是储能系统和电动汽车不可或缺的一部分，锂离子电池（LIBs）目前是延长使用寿命的储能的首选选项。为了进一步延长锂离子电池的寿命，必须加大对电池设计、制造工艺和辅助材料研发的投资。追求长耐久性给电池能量密度带来了新的挑战。电极材料的出现为提高电池的长期性能提供了有效支持。作为阴极成分的一部分，粘结剂常常被低估，但其在电极的寿命和电化学性能方面起着关键作用。通过合理的粘结剂设计来维持电极的机械完整性，是实现一致的长寿命循环和高能量密度的基本要求。本文主要聚焦于锂离子电池中常用的阴极系统，阐明粘结剂对两者的重要性，探讨新型粘结剂的应用现状、优点和缺点，并最终提出相应的优化策略。它强调了粘结剂在提高电池性能和推动锂离子电池可持续发展方面的关键作用，旨在为高性能锂离子电池的设计提供新的见解和观点。
