Abstract: Silicon-containing materials along with process for producing and uses for the same. The process includes reacting the silicon-containing materials in a fluidized bed reactor by deposition of silicon from at least one silicon precursor in pores and on the surface of porous particles. A fluidizing gas stream is provided within the fluidized bed reactor that is fully or partly induced to oscillate in a pulsed manner and propagates in the form of a wave and acts on the fluidized bed so as to form a homogeneously fluidized bed as a pulsed gas stream so as to form a homogeneously fluidized bed having a fluidization index FI of at least 0.95. Where the fluidizing gas stream has a superficial velocity which is above a measured minimum fluidization velocity of the pulsed gas stream and where the pulsation is combined with mechanical stirring as a further fluidizing aid.

Abstract: Provided are methods and systems for battery pack thermal management, such as heating and cooling of individual batteries arranged into battery packs. The methods and systems use thermal control modules, specifically configured to thermally couple to the side wall and the bottom end of each battery in a battery pack. In some examples, a thermal control module comprises a thermal plate and one or two battery engagement components, connected and thermally coupled to the thermal plate. Each battery engagement component comprises a plurality of battery receiving openings. When the batteries are installed into these openings, the side wall and the bottom end of each battery are thermally coupled to the thermal control module. Thermal fluid is circulated through at least the thermal plate to provide cooling or heating to the batteries without any direct contact between the thermal fluid and the batteries.

Abstract: Plastic material-comprising surfaces of a substrate are coated with elemental silicon by cold gas spraying by injecting a powder containing silicon into a gas and powder with a high velocity onto the substrate surface, such that the silicon forms a firmly adherent coat on the substrate surface comprising the plastics material. Apparatuses having such silicon-coated surfaces are useful in minimizing contamination of polycrystalline silicon production, processing, packaging, and transport.
