Abstract:
The present invention is directed to protected active metal negative electrodes for use in an electrochemical device such as a rechargeable battery cells, and to novel battery cells incorporating said protected electrodes. In accordance with the invention, the interior of the anode compartment includes, what is termed herein, a reservoir architecture for accommodating liquid anolyte in contact with the active metal electroactive material layer and is spatially engineered to improve service life of the instant electrode, and in particular embodiments to enhance cycle life of a battery cell in which the protected electrode is employed.

Claim (Index 5):
A double-sided protected active metal negative electrode, the electrode comprising:\n a) an active metal electroactive layer having first and second major opposing surfaces; b) a first and second substantially impervious active metal ion conductive solid electrolyte membrane, each membrane having first and second major opposing surface, the first-membrane first-surface opposing the electroactive layer first-surface and the second-membrane first-surface opposing the electroactive layer second-surface; c) a liquid phase anolyte in direct contact with the electroactive layer first-surface, the electroactive layer second-surface, the first-membrane first-surface and the second-membrane second-surface; d) a peripheral negative electrode sidewall component surrounding the periphery of the electroactive layer, the sidewall component configured to interface with the first-membrane and the second-membrane components to define an electrochemically functional hermetic anode compartment wherein the liquid anolyte and electroactive layer are disposed and therein isolated from direct contact with the external environment about the anode compartment, and further wherein each solid electrolyte membrane provides an ionic pathway for active metal ion communication into and out of the anode compartment; e) an optional current collector layer disposed within the midplane of the electroactive layer, and therein directly contacting the electroactive layer; f) an electronically conductive feedthrough component in electronic communication with the electroactive layer and the current collector when present; g) a liquid anolyte reservoir architecture disposed within the interior of the anode compartment and therein configured for accommodating liquid anolyte within the interior of the compartment, the architecture having a spatially engineered pore structure that: a) drives liquid anolyte toward the first and second surfaces of the electroactive layer and b) drives solid and/or gaseous reaction products away from the surface of the electroactive layer, the liquid anolyte reservoir architecture comprising: i) a first and second porous material network comprising liquid anolyte; and ii) a reservoir comprising liquid anolyte;\n i) wherein the first porous material network comprises a first-network porous interlayer component comprising liquid anolyte, the first-network porous interlayer positioned in direct contact with the electroactive layer and adjacently disposed between the electroactive layer first-surface and the first-membrane first-surface; and \n ii) wherein the second porous network comprises a second-network porous interlayer component comprising liquid anolyte, the second-network porous interlayer positioned in direct contact with the electroactive layer and adjacently disposed between the electroactive layer second-surface and the second-membrane first surface; \n iii) wherein the liquid anolyte in the reservoir is in flow communication with the liquid anolyte disposed in the first-network porous interlayer component and/or the liquid anolyte disposed in the second-network porous interlayer component.
