PROCESS OF PREPARING A CHEMICALLY PRE-FORMED (CPF) IRON NEGATIVE ELECTRODE WITH OXIDIZING COMPOUNDS

摘要

Provided is a process for preparing an electrode comprising an iron active material. The process comprises first fabricating an electrode comprising an iron active material, and then treating the surface of the electrode with an oxidant solution to thereby create an oxidized surface. The resulting iron electrode is thereby preconditioned prior to any charge-discharge cycle to have the assessable surface of the iron active material in the same oxidation state as in discharged iron negative electrodes active material.

1. A process for preparing an electrode comprising an iron active material, which comprises:
i) fabricating an electrode comprising an iron active material, a polyvinyl alcohol binder and sulfur, and ii) treating the surface of the electrode with an oxidant solution to thereby create an oxidized surface prior to any charge-discharge cycle.
