ELECTROCHEMICAL CELL AND METHOD OF MAKING THE SAME

摘要

A secondary cell comprising a positive cathode electrode of capacity P (mAh) in communication with a liquid or gel electrolyte; an negative anode electrode of capacity N (mAh) in communication with the electrolyte; and a separator permeable to at least one mobile species which is redox-active at least one of the anode and the cathode; designed and constructed such that the anode capacity N is smaller than that of the cathode capacity P, hence N/P<0.9.

主权项

1. A rechargeable electrochemical storage device, comprising:
an anode electrode comprising the metal form of the electro-active species, said rechargeable electrochemical storage device configured to electroplate metal at said anode electrode, said anode electrode comprising N/P<4 of electro-active material in the discharged state.
