A lithium anode is expected to be applied to next-generation batteries using inorganic solid electrolytes (ISEs). When joining Li with ISEs, interfacial reactions often cause performance degradation and have been avoided. In this report, we demonstra

Nanostructured, uncharged liquid-crystalline (LC) electrolyte molecules having bicyclohexyl and cyclic carbonate moieties have been developed for application in Li-ion batteries as quasi-solid electrolytes, which suppress leakage and combustion. Towa

We have proposed a fabrication process of submicrometer-sized zinc oxide aggregates with nano/microstructures through pyrolysis of ZIF-8 particles. Methanol solutions of zinc nitrate hexahydrate and 2-methylimidazole were used for synthesizing ZIF-8

We report advanced liquid-crystalline (LC) electrolytes for use in lithium-ion batteries (LIBs). We evaluated the potential of LC electrolytes with a half cell composed of Li metal and LiFePO4 which is a conventional positive electrode for LIBs. Low-
