摘要： A solid-state composite electrode includes active electrode particles, ionically conductive particles, and electrically conductive particles. Each of the ionically conductive particles is at least partially coated with an isolation material that inhibits inter-diffusion of the ionically conductive particles with the active electrode particles. A battery cell includes a first current collector, a solid electrolyte layer, a first solid-state composite electrode having ionically conductive particles coated with an isolation material and positioned between the first current collector and the solid electrolyte layer, a second current collector, and a second electrode positioned between the solid electrolyte layer and the second current collector. A method of forming a solid-state composite electrode includes mixing together active electrode particles and electrically conductive particles with ionically conductive particles that are each at least partially coated with an isolation material. The mixture is formed into a film via tape-casting, and sintered at a temperature greater than 600° C.

摘要： An electrochemical battery system includes at least one electrochemical cell, a thermal control system operably connected to the at least one electrochemical cell, a memory in which a physics-based model of the at least one electrochemical cell is stored and in which program instructions are stored, and a controller operably connected to the at least one electrochemical cell, the thermal control system and the memory. The controller is configured to execute the program instructions to identify a first requested operation, obtain a first generated target temperature which is based on the physics-based model and the identified first requested operation, and control the thermal control system based upon the obtained first target temperature while controlling the at least one electrochemical cell based upon the identified first requested operation.

摘要： Described herein is a polymer-electrolyte-membrane fuel cell (PEMFC) that incorporates a shunt into the membrane separator that becomes electronically conductive around a well-defined anodic onset potential, thereby preventing excessive anodic potentials at the positive electrode that would otherwise drive deleterious parasitic reactions such as catalyst dissolution or catalyst and carbon oxidation.

摘要： A battery includes an electrode that exhibits a crystal structure change when lithiated beyond a threshold potential and a battery management system. The battery management system includes a controller configured to, while the battery is online, determine the threshold potential, determine battery operating parameters based on the determined threshold potential, and operate the battery based on the determined battery operating parameters.

摘要： A high transference number, thin-film electrolyte structure suitable for a battery includes a non-conducting organic phase portion and plurality of ion-conducting inorganic phase structures. The inorganic phase structures are dispersed throughout the organic phase portion and arranged generally in a layer. The inorganic phase structures are configured to span a thickness of the organic phase portion such that a respective portion of each structure is exposed on opposite sides of the organic phase portion. Respective interfaces between the organic phase portion and the inorganic phase structures possess strong adhesion characteristics via an unbroken chain of ionic bonds and/or covalent bonds. The interfaces in some embodiments include at least one adhesion promoter configured to promote adhesion between the organic phase portion and the inorganic phase structures. The inorganic phase structures in some embodiments have surfaces that are modified using a surface modification agent to promote adhesion to the organic phase portion.

摘要： An electrolyte structure for a battery cell with a lithium metal anode has a first side configured to contact the anode and a second side facing opposite the first side. The electrolyte structure includes a first region that is adjacent to the first side and extends towards the second side and a second region disposed between the first region and the second side. The first region has a first composition of materials that is electronically insulating such that the electrolyte is stable against the lithium metal anode. The second region has a second composition of materials that is different than the first composition and has typical electrolyte properties such as mechanical strength, stability against a cathode, and ionic conductivity. The first region and the second region define a compositional gradient across a thickness of the electrolyte structure. The compositional gradient is continuum-fabricated at one point via a gradient growth method.

摘要： Solid electrolytes have a favorable combination of properties such as high conductivity, high transference number, optimum processability, and low brittleness. A composite electrolyte includes some amount of a class of network polymer electrolytes with high transference number and high room temperature conductivity, and an additional polymeric component to contribute mechanical integrity and/or processability. The solid electrolytes can include a network polymer having linked nodes composed of a tetrahedral arylborate composition and a linear polymer combined with the network polymer as a composite. The solid electrolytes can be used in thin films and in solid-state batteries.

摘要： A metal/air battery includes an oxygen management system that delivers oxygen to the battery during a discharge cycle. The oxygen management system includes an oxygen separations unit and an oxygenated gas supply reservoir that are fluidly coupled to a positive electrode of the battery via a valve system. The valve system selectively places the oxygen separations unit and the oxygenated gas supply reservoir in fluid communication with the positive electrode during the discharge cycle. The oxygen management system also includes a compressor with an outlet fluidly coupled to the oxygenated gas supply reservoir and an inlet fluidly connected to the oxygen separations unit via the valve system. The valve system selectively places the oxygen separations unit in fluid communication with the oxygenated gas supply reservoir during one or more of the discharge cycle and a charge cycle of the battery.

摘要： Devices, systems, and techniques for identifying a dendrite material within a battery. The method comprising receiving, by a battery management system, an output from sensing circuitry within the battery indicative of a first voltage level, detecting, by the battery management system, a change from the first voltage level to a second voltage level that is indicative of an internal short within a sensing sheet, determining by the battery management system, a resistance and a two-dimensional position of the internal short within the sensing sheet, and identifying, by the battery management system, a dendrite material based on the resistance of the internal short.
