Electrochemical element with ceramic particles in the electrolyte layer

摘要

A solid-state electrochemical element comprising a layer of electrolyte which is sandwiched between cathode and anode electrodes, which electrodes comprise an alkali metal ion and host material of a spinel type structure containing active component and an electronically conductive component, which components are at least partly covered by a liquid film coating and are embedded in a matrix binder material, wherein the electrolyte layer comprises ceramic electrolyte particles that are essentially free of electronically conductive components and comprise less than 1% by weight of dissolved alkali containing salt, which particles are at least partly covered by a liquid film coating and are embedded in a matrix binder material.
