Abstract

A quasi-solid-state battery formed from non-gas evolving in-situ curing of a quasi-solid-state electrolyte that includes a high swelling polymer made from a monomer with good compatibility with liquid electrolytes, and has a good reactivity for facile non-gas evolving in-situ polymerization. The monomer can be based on acrylate polymerization chemistry or an allyl group polymerization chemistry.

The resulting QSE additionally has high ionic conductivity, allowing for a high battery output, and a wide electrochemical window (stable for lithium metal anode and high-voltage cathodes). The resulting quasi solid electrolyte battery is not only easy to fabricate using conventional battery manufacturing practices, the non-gas evolving in-situ polymerization causes the QSE to be uniformly distributed within the battery, ensuring high-quality, safe battery performance and longevity.

Abstract

A multimode immersion cooling system includes a first, single-phase immersion cooling mode and a second, two-phase immersion cooling mode. The system operates in a single phase mode and reserves a two-phase mode for peak energy consumption periods. A single thermal transfer fluid is used for both modes, remaining in a liquid phase in a first single-phase immersion cooling mode and vaporizing when the thermal transfer fluid temperature reaches its boiling point in a second two-phase immersion cooling mode. A heat exchanger extracts thermal energy from heated thermal transfer fluid in the single phase mode while a condenser cools vaporized thermal transfer fluid to condense the vapor during the second, two-phase immersion cooling mode. A controller determines whether the multimode immersion cooling system operates in the single-phase mode or the second two-phase mode, or both.

Abstract

A method of manufacturing a lightweight thermal insulating cellular cement-based material and a lightweight thermal insulating cellular cement-based board made thereof are disclosed. A binder, an activator, and a blowing agent are mixed to obtain a mixture. The mixture is homogenized to form a cement slurry, which is poured into a mold afterwards. With the help of the activator and an increased temperature of the mold, the cement slurry in the mold will be activated and start foaming and curing to form a cellular cement-based material. The cellular structure is constructed by decomposition of the blowing agent to form a plurality of closed-cell bubbles, which are fixed in the cement slurry during the curing. After the formation, the mold is removed to obtain the cellular cement-based material. The material exhibits high integrity fire resistance and extraordinary insulation fire resistance.

Abstract

Provided is a germ-repellent polymer structure including a base plastic selected from polypropylene homopolymer, polypropylene impact copolymer, or acrylonitrile butadiene styrene; and a hydration layer, the hydration layer including one or more hydrophilic additives formed on the base plastic optionally in the presence of an intermediate plastic that is compatible to both the base plastic and hydrophilic additives for stabilizing the hydration layer on some base plastics. In some embodiment, the introduction of hydration layer to the base plastic through the intermediate plastic imparts germ repellency by introducing sufficient hydroxyl groups onto the surface of the base plastic in order to trap water molecules into a polymer matrix of the base plastic. The change in mechanical strength of the base plastic before and after the introduction of the hydration layer is less than 20% of an original mechanical strength, where the original mechanical strength corresponds to a strength of the base plastic before formation of the hydration layer.
