The electrical double layer (EDL) is critical to the operation of devices for electrochemical energy storage and conversion. Existing EDL models in solid electrolytes simulate the space charge layer and lack a complete treatment of the interfacial core region. The core layer exhibits significant variations in defec

An enhanced ionic conductivity is observed when mixing a solid electrolyte with another solid, which is caused by the formation of a space charge layer at the interface. The finding provides a new str...
