Compositionally complex ceramics (CCCs), including high-entropy ceramics(HECs) as a subclass, offer new opportunities of materials discovery beyond thetraditional methodology of searching new stoichiometric compounds. Herein, weestablish new strategies of tailoring CCCs via a seamless combination of (1)non-equimolar compositional designs and (2) controlling microstructures andinterfaces. Using oxide solid electrolytes for all-solid-state batteries as anexemplar, we validate these new strategies via discovering a new class ofcompositionally complex perovskite oxides (CCPOs) to show the possibility ofimproving ionic conductivities beyond the limit of conventional doping. As anexample (amongst the 28 CCPOs examined), we demonstrate that the ionicconductivity can be improved by >60% in(Li0.375Sr0.4375)(Ta0.375Nb0.375Zr0.125Hf0.125)O3-{\delta}, in comparison withthe state-of-art (Li0.375Sr0.4375)(Ta0.75Zr0.25)O3-{\delta} (LSTZ) baseline,via maintaining comparable electrochemical stability. Furthermore, the ionicconductivity can be improved by another >70% via grain boundary (GB)engineering, achieving >270% of the LSTZ baseline. This work suggeststransformative new strategies for designing and tailoring HECs and CCCs,thereby opening a new window for discovering materials for energy storage andmany other applications.
