The monomer composition includes A) an alkylene oxide-based monomer and B) a siloxane monomer. A copolymer electrolyte precursor composition is made for preparation of a solid polymer electrolyte. A polymerization method prepares solid copolymer electrolyte. A copolymer, a solid copolymer electrolyte, and a solid-state lithium secondary battery are made. A method to prepare a solid-state lithium secondary battery is developed, and another method improves electrolyte mechanical property, ionic conductivity, and/or cycling performance in a lithium secondary battery by preparing a solid polymer electrolyte the monomer. An electrochemical device and a device are also provided.

Abstract: Systems and methods are provided for expanding the operating envelope for an FCC reaction system while also reducing or minimizing the net environmental CO2 emissions associated with the FCC reaction system and/or the resulting FCC products. In some aspects, reducing or minimizing net environmental CO2 emissions can be achieved during processing of unconventional feeds, such as feeds that are traditionally viewed as having insufficient tendency to coke in order to maintain heat balance within an FCC reaction system. In other aspects, this can correspond to expanding the production of diesel within an FCC reaction system by modifying the reaction conditions in a manner that can cause a reaction system to fall out of heat balance (relative to the heat needed to maintain a target operating temperature) even when using conventional feeds.

Abstract: Systems and methods are provided for improving the flow distribution in the high temperature zone of a cyclic flow reactor, such as a reverse flow reactor. The systems can include a plurality of mixing plates that can facilitate mixing of flows that have been maintained separately until a mixing location. Based in part on the use of a plurality of mixing plates, methods are provided for operating a reverse flow reactor with a temperature profile that has improved uniformity across the cross-section of the reactor. In some aspects, a flame diffuser can be included downstream from the plurality of mixing plates to further improve the uniformity of the temperature distribution.

Abstract: Systems and methods are provided for using a high heat capacity gas as at least a portion of the diluent during the regeneration step of a reverse flow reactor process. Instead of using nitrogen or air as the primary diluent gas, CO2 and/or H2O can be added as diluent gas for the regeneration step in the reaction cycle. Increasing the heat capacity of the diluent gas provides a reduction in the peak temperature within the reactor relative to the amount of fuel combusted during regeneration. This can allow for a reduction in the volume of diluent used during regeneration and/or an increase in the amount of fuel used. Reducing the volume of diluent can reduce the pressure drop during regeneration, which can provide a corresponding reduction in the amount of compression required for recycle of the diluent. Increasing the amount of fuel can allow for a corresponding increase in the amount of endothermic reaction performed during the reaction step.

Abstract: Systems and methods are provided for performing hydrocarbon reforming within a reverse flow reactor environment (or another reactor environment with flows in opposing directions) while improving management of CO2 generated during operation of the reactor. The improved management of CO2 is achieved by making one or more changes to the operation of the reverse flow reactor. The changes can include using an air separation unit to provide an oxygen source with a reduced or minimized content of nitrogen and/or operating the reactor at elevated pressure during the regeneration stage. By operating the regeneration at elevated pressure, a regeneration flue gas can be generated that is enriched in CO2 at elevated pressure. The CO2-enriched stream can include primarily water as a contaminant, which can be removed by cooling while substantially maintaining the pressure of the stream. This can facilitate subsequent recovery and use of the CO2.

Abstract: A method of measuring a sample that includes at least one reactant that can be oxidised and reduced between at least one working electrode and a counter electrode. The method involves: applying across the working and counter electrodes a cycle of at least three pulses, and measuring current at the working electrode during each pulse, wherein the at least three pulses comprise at least one over-potential pulse that has an amplitude equal to or greater than an oxidation or a reduction peak potential of the reactant; at least one under-potential pulse of amplitude less than the at least one over-potential pulse, and at least one other over-potential pulse or under-potential pulse.
