摘要： A discharged electrochemical cell as described herein comprises an electrochemically reactive metal-containing cathode (e.g., Li, Na, Mg, or Zn; preferably Li) and a layered anode with an electrolyte therebetween. The layered anode comprises a conductive substrate and a reactive film of a metal, a semimetal, a metal oxide, or a semimetal oxide on the surface of the substrate. The reactive film is capable of reversibly alloying with, reversibly forming a mixed phase with, or reversibly reacting with, metal from cathode during charging of cell, and releasing the metal back to the cathode during discharge of the cell.
