Abstract
A positive electrode for an electrochemical cell of a secondary lithium metal battery may include an aluminum metal substrate and a protective layer disposed on a major surface of the aluminum metal substrate. The protective layer may include a conformal aluminum fluoride coating layer. A positive electrode active material layer may overlie the protective layer on the major surface of the aluminum metal substrate. The positive electrode active material layer may include a plurality of interconnected pores, which may be infiltrated with a nonaqueous electrolyte that includes a lithium imide salt.
