Outline

We challenge a construction of scientific principle to develop the functional inorganic crystals with hierarchically controlled structures, ranging from 0.1 nm to 100 μm (crystal phase-interface), which significantly reduced energy losses and/or those for highly efficient energy use in all-solid-state lithium ion rechargeable batteries. To accomplish the high performance all-solid-state lithium ion rechargeable batteries, having seamless ion conducting path from positive to negative electrodes, it is indispensable to establish design techniques for the control and optimization of phase interface structures, including flux-based growth of shape controlled crystals, predictive simulation of ion conduction path in the crystals, orientation of crystal face, controlling spaces and gaps of pattered crystal layers, interface bonding with atomic-scale, and visualization of ion conduction path in the crystals
