dc.description.abstract | Polymeric single lithium (Li)-ion conductors (SICs), along with inorganic conducting materials such as sulfides and oxides, have received significant attention as promising solid-state electrolytes. Yet their practical applications have been plagued predominantly by sluggish ion transport. Here, a new class of quasi-solid-state SICs based on anion-rectifying semi-interpenetrating polymer networks (semi-IPNs) with reticulated ion nanochannels are demonstrated. This semi-IPN SIC (denoted as sSIC) features a bicontinuous and nanophase-separated linear cationic polyurethane (cPU), which supports single-ion conducting nanochannels, and ultraviolet-crosslinked triacrylate polymer, which serves as a mechanical framework. The cPU phase is preferentially swollen with a liquid electrolyte and subsequently allows anion-rectifying capability and nanofluidic transport via surface charge, which enable fast Li+ migration through ion nanochannels. Such facile Li+ conduction is further enhanced by tuning ion-pair (i.e., freely movable anions and cations tethered to the cPU chains) interaction. Notably, the resulting sSIC provides high Li+ conductivity that exceeds those of commercial carbonate liquid electrolytes. This unusual single-ion conduction behavior of the sSIC suppresses anion-triggered interfacial side reactions with Li-metal anodes and facilitates electrochemical reaction kinetics at electrodes, eventually improving rate performance and cycling retention of Li-metal cells (comprising LiNi0.8Co0.1Mn0.1O2 cathodes and Li-metal anodes) compared to those based on carbonate liquid electrolytes. | - |
