Figure 1 (IMAGE) National Research Council of Science & Technology Caption Summary of new technology to control ionic conductivity and elastic modulus by forming fully halogenated argyrodites. By controlling the halogenation rate, a solid electrolyte was synthesized for all-solid-state batteries was synthesized; this electrolyte maximizes ionic conductivity while having a low elastic modulus.
