    摘要： Described herein are methods, air cathodes or electrochemical cell systems configured to reduce or alleviate leakage of electrolyte within air cathodes. A method for electrolyte leakage management in an electrochemical cell system includes: configuring a plurality of air cathodes within an electrochemical cell system, each of the plurality of air cathodes comprising a frame, a membrane oxygen electrode attached to the frame to define a sealed interior cavity, an air inlet communicative with the interior cavity, a liquid outlet communicative with the interior cavity; positioning the liquid outlet lower than the air inlet; and draining electrolyte leakage from the interior cavity through the liquid outlet. An electrochemical cell system configured for electrolyte leakage management includes: a housing; an electrolyte disposed in the housing; a metallic material, when positioned in the first spaces, forms one or more discharging anodes; one or more charging anodes and one or more charging cathodes at least partially immersed in the electrolyte; and one or more air cathodes immersed in the electrolyte and one or more first spaces between the oxygen cathodes, each of the one or more air cathodes comprising 1) a frame, 2) a membrane oxygen electrode attached to the frame to define an interior cavity, 3) an air inlet communicative with the interior cavity, 4) an air outlet communicative with the interior cavity, 5) a liquid outlet communicative with the interior cavity, 6) the liquid outlet positioned lower than the air inlet.

    摘要： The present invention provides a fiber-reinforced aerogel material which can be used as insulation in thermal battery applications. The fiber-reinforced aerogel material is highly durable, flexible, and has a thermal performance that exceeds the insulation materials currently used in thermal battery applications. The fiber-reinforced aerogel insulation material can be as thin as 1 mm less, and can have a thickness variation as low as 2% or less. Also provided is a method for improving the performance of a thermal battery by incorporating a reinforced aerogel material into the thermal battery. Further provided is a casting method for producing thin fiber-reinforced aerogel materials.

    摘要： A device for storing electrical energy is disclosed. The device includes an electrochemical cell having a cathode chamber for holding a liquid cathode material and an anode chamber for holding a liquid anode material. The cathode and anode chambers are separated by a solid electrolyte, wherein the solid electrolyte is surrounded by a planar construction having openings, through which the cathode material can flow. The planar construction is made of an electrically conductive material. The cathode chamber includes at least one segment, wherein each segment has a jacket composed of an electrically conductive material and the jacket is fastened to the planar construction having openings in a fluid-tight and electrically conductive manner and wherein each segment is filled with a porous felt or a porous material different from porous felt. A method for assembling and starting up the device and a method for operating the device is also disclosed.

    摘要： This disclosure relates to a methane-assisted metal ion battery. The methane-assisted metal ion battery includes an electrolyte including a salt of a metal in aqueous state. The metal is selected from an alkali metal, an alkali earth metal, a transition metal, or a combination thereof. The methane-assisted metal ion battery further includes a positive electrode including a compound of the metal. The positive electrode is in contact with the electrolyte. The methane-assisted metal ion battery further includes a negative electrode electrically coupled to the positive electrode. The negative electrode includes an electrocatalyst and is configured to reduce atmospheric methane to generate carbon nanoparticles and hydrogen molecules (H2) when the battery is charging and to oxidize hydrogen molecules (H2) to generate hydrogen ions (H+) and free electrons when the battery is discharging. The methane-assisted metal ion battery further includes a separator including a permeable membrane.
