dc.description.abstractHerein is reported a novel piperidinium tethered silica nanoparticle hybrid electrolyte with 1M LiTFSI and PC for use in lithium metal batteries. This unique NOHMs electrolyte provides a solid-like physical barrier to dendritic growth due to the jamming phase transition while maintaining use of the piperidinium chemistry to achieve the same effect. Through a battery of characterizations, it was found that the tethered electrolyte displayed thermal stability up to 380 °C, high conductivities that were weakly affected by increases in viscosity and followed a VFT fit, low interfacial resistances, could be tuned to exhibit MPa scale moduli, and had an SEI layer that was able to efficiently stem dendritic growth. Polarization experiments of lithium symmetric cells showed long short circuit times whereas cycling experiments of symmetric cells showed no sign of short circuit, even after 1000 hours. Using a carbon modified lithium titanate counterelectrode, the cell exhibited stable voltage plateaus indicating electrolyte robustness during battery operation, capacity retentions of 87% over 1000 cycles, and no short circuit over 2000 cycles.en_US
