Developing high-performance battery systems requires the optimization of every battery component, from electrodes and electrolyte to binder systems. However, the conventional strategy to fabricate battery electrodes by casting a mixture of active materials, a nonconductive polymer binder, and a conductive additive onto a metal foil current collector usually leads to electronic or ionic bottlenecks and poor contacts due to the randomly distributed conductive phases. When high-capacity electrode materials are employed, the high stress generated during electrochemical reactions disrupts the mechanical integrity of traditional binder systems, resulting in decreased cycle life of batteries. Thus, it is critical to design novel binder systems that can provide robust, low-resistance, and continuous internal pathways to connect all regions of the electrode.

用于高能，大功率锂离子电池的新型粘合剂系统的材料和结构设计

开发高性能电池系统需要优化每个电池组件，从电极，电解质到粘合剂系统。然而，通过将活性材料，非导电聚合物粘合剂和导电添加剂的混合物浇铸到金属箔集电器上来制造电池电极的常规策略通常会由于随机分布的导电相而导致电子或离子瓶颈以及不良的接触。当使用大容量电极材料时，电化学反应过程中产生的高应力破坏了传统粘合剂系统的机械完整性，导致电池循环寿命缩短。因此，设计能够提供坚固，低电阻，
