An inorganic ion-conducting membrane treated to modify its surface properties can improve battery cell performance. Membrane surfaces positioned to directly interface with liquid electrolyte(s) on one or both of its major surfaces can be modified to mitigate polarization effects arising from ionic space charges at the solid electrolyte/liquid electrolyte interface when disposed in a battery cell. This surface modification can include fluid treatments that modify the ionic space charge layer to reduce battery cell polarization. The cell polarization can be reduced by at least 10 mV, 50 mV or at least 100 mV as a result of using this surface-modified membrane compared to the same membrane that was not surface-modified.

Lithium sulfur batteries and electrolytes and sulfur cathodes thereof
Lithium sulfur battery cells that use water as an electrolyte solvent provide significant cost reductions. Electrolytes for the battery cells may include water solvent for maintaining electroactive sulfur species in solution during cell discharge and a sufficient amount of a cycle life-enhancing compound that facilitates charging at the cathode. The combination of these two components enhances one or more of the following cell attributes: energy density, power density and cycle life. For instance, in applications where cost per Watt-Hour (Wh) is paramount, such as grid storage and traction applications, the use of an aqueous electrolyte in combination with inexpensive sulfur as the cathode active material can be a key enabler for the utility and automotive industries, for example, providing a cost effective and compact solution for load leveling, electric vehicles and renewable energy storage. Sulfur cathodes, and methods of fabricating lithium sulfur cells, in particular for loading lithium sulfide into the cathode structures, provide further advantages.

A composite solid electrolyte includes a monolithic solid electrolyte base component that is a continuous matrix of an inorganic active metal ion conductor and a filler component used to eliminate through porosity in the solid electrolyte. In this way a solid electrolyte produced by any process that yields residual through porosity can be modified by the incorporation of a filler to form a substantially impervious composite solid electrolyte and eliminate through porosity in the base component. Methods of making the composites are also disclosed. The composites are generally useful in electrochemical cell structures such as battery cells and in particular protected active metal anodes, particularly lithium anodes, that are protected with a protective membrane architecture incorporating the composite solid electrolyte. The protective architecture prevents the active metal of the anode from deleterious reaction with the environment on the other (cathode) side of the architecture, which may include aqueous, air and organic liquid electrolytes and/or electrochemically active materials.
Protected anode architectures for active metal anodes have a polymer adhesive seal that provides a hermetic enclosure for the active metal of the protected anode inside an anode compartment. The compartment is substantially impervious to ambient moisture and battery components such as catholyte (electrolyte about the cathode), and prevents volatile components of the protected anode, such as anolyte (electrolyte about the anode), from escaping. The architecture is formed by joining the protected anode to an anode container. The polymer adhesive seals provide a hermetic seal at the joint between a surface of the protected anode and the container.
Electrochemical energy storage devices, such as alkali metal-oxygen battery cells (e.g., non-aqueous lithium-air cells), have a cathode architecture with a porous structure and pore composition that is tailored to improve cell performance, especially as it pertains to one or more of the discharge/charge rate, cycle life, and delivered ampere-hour capacity. A porous cathode architecture having a pore volume that is derived from pores of varying radii wherein the pore size distribution is tailored as a function of the architecture thickness is one way to achieve one or more of the aforementioned cell performance improvements.
Protected anode architectures have ionically conductive protective membrane architectures that, in conjunction with compliant seal structures and anode backplanes, effectively enclose an active metal anode inside the interior of an anode compartment. This enclosure prevents the active metal from deleterious reaction with the environment external to the anode compartment, which may include aqueous, ambient moisture, and/or other materials corrosive to the active metal. The compliant seal structures are substantially impervious to anolytes, catholyes, dissolved species in electrolytes, and moisture and compliant to changes in anode volume such that physical continuity between the anode protective architecture and backplane are maintained. The protected anode architectures can be used in arrays of protected anode architectures and battery cells of various configurations incorporating the protected anode architectures or arrays.

Substantially impervious lithium super ion conducting membranes
A composite solid electrolyte includes a monolithic solid electrolyte base component that is a continuous matrix of an inorganic active metal ion conductor and a filler component used to eliminate through porosity in the solid electrolyte. In this way a solid electrolyte produced by any process that yields residual through porosity can be modified by the incorporation of a filler to form a substantially impervious composite solid electrolyte and eliminate through porosity in the base component. Such composites may be made by disclosed techniques. The composites are generally useful in electrochemical cell structures such as battery cells and in particular protected active metal anodes, particularly lithium anodes, that are protected with a protective membrane architecture incorporating the composite solid electrolyte.
Protected anode architectures for active metal anodes have a polymer adhesive seal that provides an hermetic enclosure for the active metal of the protected anode inside an anode compartment. The compartment is substantially impervious to ambient moisture and battery components such as catholyte (electrolyte about the cathode), and prevents volatile components of the protected anode, such as anolyte (electrolyte about the anode), from escaping. The architecture is formed by joining the protected anode to an anode container. The polymer adhesive seals provide an hermetic seal at the joint between a surface of the protected anode and the container.

A drug electrode assembly usefully employed in an electrotransport device for the delivery of drugs across a tissue surface includes an electrode, a drug reservoir which stores the drug (including an ionized (e.g., anionic) or neutrally charged drug species), and a liquid impermeable solid-state assist ion conducting barrier layer interposed between the electrode and the drug reservoir. The barrier layer can be a single-ion conductor of a specific (unique) species of ion called the assist ion. During drug delivery, the assist ion moves across the barrier layer into or out of the drug reservoir, and as the assist ion crosses the barrier layer/drug reservoir interphase, the drug species moves to the tissue surface. The assist ion can be, for example, sodium ions (Na+), and the electrode can be an electrode of the assist ion (i.e., a sodium electrode).
