Abstract
A negative electrode according to various aspects of the present disclosure includes a negative electroactive material and a layer. The negative electroactive material includes a lithium-aluminum alloy. The layer is disposed directly on at least a portion of the negative electroactive material and coupled to the negative electroactive material. The layer includes anodic aluminum oxide and has a plurality of pores. The present disclosure also provides an electrochemical cell including the negative electrode. In certain aspects, the negative electroactive material is electrically conductive and functions as a negative electrode current collector such that the electrochemical cell is free of a distinct negative electrode current collector component. In certain aspects, the layer is ionically conductive and electrically insulating and functions as a separator such that the electrochemical cell is free of a distinct separator component. In various aspects, the present disclosure also provides a method of making the negative electrode.
