System for producing lithium metal batteries

A system for producing lithium metal batteries can comprise a manufacturing stage configured to fabricate a negative electrode. The manufacturing stage can comprise a lithium supply and an electrochemical cell, wherein the electrochemical cell comprises a lithium-ion selective membrane. The system for producing lithium metal batteries can comprise a battery assembly stage configured to integrate the negative electrode, the lithium-ion selective membrane, and a positive electrode into a battery. The manufacturing stage can be operatively coupled to the battery assembly stage, integrated in the same facility contained in an area of no greater than 10 km.
