电极的优化是提升锂电池性能的重要手段。电极可视为一种复合材料，主要由活性物质、导电剂和粘结剂组成。电极应具备连通导电、导离子的空间结构，能够在往复充放电中缓冲体积变化、维持结构稳定，这其中粘结剂所起的关键作用在近些年被逐渐了解。研究发现电极粘结剂的粘弹性、导电、导离子能力对电池充放电速率、循环寿命等存在显著影响。但是，目前相关研究多局限在少数几种电极粘结剂的改性和复配，或将其它非电极粘结剂尝试用于电极，鲜有研究能分析电极各种需求，基于结构设计制备粘结剂分子来满足这些需求。因此，申请者分析电极需要，提出一导电、导离子、高粘结性、高弹性理想电极粘结剂，研究该多功能聚合物的制备和精确调控，其链结构、相形态与各功能间关系，粘结剂与电池性能间关系。该项研究对多功能聚合物的设计与合成、结构与性能间关系知识的扩展有重要的科学意义，电极粘结剂的技术进步对锂电池性能提升、高比容量电池研发有着重要的应用价值。

Optimization of the electrode is an important means to improve the performance of lithium batteries. Electrode can be regarded as a composite material mainly composed of active substance, conductive agent and binder. The electrode should have a spatial structure with connected electron and ion transfer channels. It should be able to buffer the volume change during the charge and discharge process and maintain the structure stable. To achieve this purpose, binder plays an important role, which was not realized until recent years. Studies reveal that the viscoelasticity, electron conductivity and ion conductivity of binders have obvious effects on the battery charge and discharge rate, cycle life and so on. However, most related studies are limited to the modification and complex of a few binders, or employment of other existing binders for electrodes. Few studies have analyzed the requirements from electrodes and prepare one binder molecule to satisfy all these requirements. Accordingly, based on the needs from electrode, an electrically conductive, ion-conducting, highly adhesive and elastic ideal electrode binder is proposed in the current proposal. The research will focus on the preparation and precise regulation of this multi-functional polymeric binder, the relationship between the polymer chain structure, phase morphology and functions, and the relationship between the binder and the battery performance. The research from the current proposal will have scientific significance on knowledge extension about the design and synthesis of multifunctional polymers, the relationship between their structure and properties. The improvement of electrode binder has important practical values on the performance improvement of lithium batteries and the development of high energy density batteries.
