Abstract

Systems and methods of the various embodiments may provide metal air electrochemical cell architectures. Various embodiments may provide a battery, such as an unsealed battery or sealed battery, with an open cell arrangement configured such that a liquid electrolyte layer separates a metal electrode from an air electrode. In various embodiments, the electrolyte may be disposed within one or more vessel of the battery such that electrolyte serves as a barrier between a metal electrode and gaseous oxygen. Systems and methods of the various embodiments may provide for removing a metal electrode from electrolyte to prevent self-discharge of the metal electrode. Systems and methods of the various embodiments may provide a three electrode battery configured to operate each in a discharge mode, but with two distinct electrochemical reactions occurring at each electrode.

Description

[0001] related application [0002] This application claims the benefit of priority to U.S. Provisional Patent Application 62 / 692,400, filed June 29, 2018, entitled "Unsealed Metal-Air Electrochemical Cell Architecture," the entire contents of which are incorporated herein by reference for all purposes. This application is related to U.S. Nonprovisional Patent Application Attorney Docket No. 9284-001US, entitled "Aqueous Polysulfide-Based Electrochemical Cell," filed on the same date as this application, and this application is related to U.S. Nonprovisional Patent Application Attorney Docket No. 9284-012US for "Rolling Diaphragm Seal." The entire contents of these two related applications are hereby incorporated by reference for all purposes. Background technique [0003] Batteries that are isolated from the environment, known as sealed batteries, face enormous challenges. For example, sealing the structural elements of the battery, such as the current collector, requires ...
