A nanohybridization strategy is presented for the fabrication of high performance lithium ion batteries based on redox-active organic molecules. The rearrangement of electroactive aromatic molecules from bulk crystalline particles into molecular layers is achieved by non-covalent nanohybridization of active molecules with conductive scaffolds. As a result, nano-hybrid organic electrodes in the form of a flexible self-standing paper-free of binder/additive and current collector-are synthesized, which exhibit high energy and power densities combined with excellent cyclic stability.
提出了一种基于氧化还原活性有机分子的高性能锂离子电池的纳米杂化策略。通过将活性分子与导电支架进行非共价纳米杂化,将电活性芳族分子从块状晶体颗粒中重新排列成分子层。因此,合成了无粘结剂/添加剂和集流器的柔性自支撑纸状纳米杂化有机电极,其具有高能量和功率密度以及优异的循环稳定性。
