Title: Lithium battery

Abstract

The present disclosure describes various types of batteries, including lithium-ion batteries having an anode assembly comprising: an anode comprising a first porous ceramic matrix having pores; and a ceramic separator layer affixed directly or indirectly to the anode; a cathode; an anode-side current collector contacting the anode; and anode active material comprising lithium located within the pores or cathode active material located within the cathode; wherein, the ceramic separator layer is located between the anode and the cathode, no electrically conductive coating on the pores contacts the separator layer, and in a fully charged state, lithium active material in the anode does not contact the separator layer. Also disclosed are methods of making and methods of using such batteries.
