Abstract
Disclosed are electrochemical devices and methods for making electrochemical devices such as metal infiltrated electrodes for solid state lithium ion and lithium metal batteries. In one method for forming an electrode, a metal is infiltrated into the pore space of the active material of the electrode providing improved electronic conductivity to the electrode. The electrode may also include a solid-state ion conducting material providing improved ion conductivity to the electrode. Before infiltration of the metal, a stabilization coating may be applied to the active material and/or the solid-state ion conducting material to the stabilize electrode interfaces by slowing, but not eliminating, the chemical reactions that occur at elevated temperatures during sintering of the active material and/or the solid-state ion conducting material forming the electrode.
