Title: Batteries comprising vented electrodes. [bipolar electrodes, circulating electrolyte]

Abstract

A high-energy density battery is described. The bipolar electrodes are constituted of walls of impervious material, preferably graphite. On the outside of the wall is a highly electropositive metal such as zinc; on the inside is a porous electrode of carbon (preferably). The electrodes of a cell constitute the opposite-facing electrodes on adjoining impervious walls. During charging, zinc is deposited on the impervious wall, as by plating from a zinc chloride electrolyte, and simultaneously chlorine is generated at the anode. During operation, zinc chloride solution containing dissolved chlorine is passed through the cell; Zn ..-->.. Zn ion and Cl ..-->.. Cl/sup -/. The electrolyte is then re-enriched and recirculated. Holes drilled in the upper part of the electrolyte channels permit venting of trapped gas. (RWR)
