摘要： The present invention provides one with an iron electrode employing a binder comprised of polyvinyl alcohol (PVA) binder. In one embodiment, the invention comprises an iron based electrode comprising a single layer of a conductive substrate coated on at least one side with a coating comprising an iron active material and a binder, wherein the binder is PVA. This iron based electrode is useful in alkaline rechargeable batteries, particularly as a negative electrode in a Ni-Fe battery.

摘要： Cathode active materials for alkaline cells are disclosed. In particular, the cathode structures encompass conductive carbons introduced to the cathode so as to have a specific spatial orientation and/or a multi-carbon structure. The overall intent is to leverage the conductor(s) provided to the cathode structure to improve electronic and ionic conductance and, by extension, improve battery discharge performance.
