extracted, a phase transition occurs with significant strain, and therefore we have to develop new electrode materials with robust structures that can be stably used even in such a situation, and we also aim to construct a new battery system itself.<br \/>\nBy controlling microstructures of oxides and alloys at the atomic structure level and further controlling mesoscale microstructure formation, we aim to change the thermodynamic potential and facilitate diffusion of carrier ions.
