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 1):
A protected active metal negative electrode, comprising:\n a) an active metal electroactive layer having first and second opposing surfaces; b) a negative electrode cover plate component having first and second major opposing surfaces, the cover plate first surface opposing the second surface of the electroactive layer; c) a substantially impervious active metal ion conductive solid electrolyte membrane having first and second opposing surfaces, the first membrane surface opposing the first electroactive layer surface; d) a liquid phase anolyte in direct contact with the electroactive layer and the membrane; e) a peripheral negative electrode sidewall component surrounding the periphery of the electroactive layer, the sidewall component configured to interface with the cover plate component and solid electrolyte membrane component 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 the solid electrolyte membrane provides an ionic pathway for active metal ion communication into and out of the anode compartment; f) an optional current collector layer having first and second opposing surfaces, the first current collector surface adjacently disposed in direct contact with the second electroactive layer surface; g) an electronically conductive feedthrough component in electronic communication with the electroactive layer, wherein the feedthrough component provides an electronic pathway for the through conduction of electrons into and out of the anode compartment; and h) a liquid anolyte reservoir architecture disposed within the interior of the anode compartment and therein configured for accommodating liquid anolyte within the anode compartment, the architecture having a spatially engineered pore structure that: i) drives liquid anolyte toward the first surface of the electroactive layer and ii) drives solid and/or gaseous reaction products away from the first surface of the electroactive layer, the liquid anolyte reservoir architecture comprising:\n i) a porous material network that is devoid of electroactive material, the network comprising a porous material interlayer component comprising a first amount of liquid anolyte, the interlayer adjacently disposed between the electroactive layer and the solid electrolyte membrane and in direct contact with the first surface of the electroactive layer; and \n ii) a reservoir comprising a second amount of liquid anolyte that is in flow communication with the anolyte of the interlayer.
