Presented in the present disclosure are nanocomposites and batteries which are resistant to thermal runaway and may be used as cathode materials in batteries that tolerate operation at high temperatures. The nanocomposites include a nonconducting polymer and a carbon filler which includes a plurality of ultrathin sheets of a porous carbon material. The nonconducting polymer and carbon filler act in synergy to provide improved thermal stability, increased surface area, and enhanced electrochemical properties to the nanocomposite. For example, a battery that includes the nanocomposite as a cathode material was shown to have an enhanced performance and stability over a broad temperature range from room temperature to high temperatures (for example, of 100° C. or more). These batteries fill an important need by providing a safe and reliable power source for devices that are operated at high temperatures such as the downhole equipment used in the oil industry.

A method and system of igniting one or more filaments for silicon production includes applying an output voltage to the one or more filaments using a transformer connected with the one or more filaments. In addition, the method includes supplying, in combination with the application of the output voltage, a current to a primary winding of the transformer via a choke to limit the current to a first predetermined current threshold range. The combination of the supplied current and applied output voltage allows a predetermined output range to be generated from a power supply device initially required to ignite the one or more filaments.

The present invention provides a low pressure generating plasma reactor closed loop process, comprising: feeding a fresh feed gas flow and a fresh feed absorption liquid flow to a plasma reactor closed loop comprising a condenser, a liquid loop, a recycle gas loop, and a plasma generator; converting feed gas to reactive plasma products in the plasma generator; quenching and absorbing the reactive plasma products into an absorption liquid circulating in the liquid loop where the reactive plasma products react to form liquid reaction products, thereby generating low pressure in the closed loop; monitoring the composition and low pressure of the recycle gas loop and, if the pressure increases, adjusting the composition of the fresh feed gas flow and/or fresh feed absorption liquid flow to bring the composition of the feed gas towards stoichiometric ratio with the absorbed reactive plasma products; extracting circulating absorption liquid, containing the liquid reaction products, from the plasma reactor closed loop as a product flow. The present invention also provides a low pressure generating plasma reactor closed loop system, comprising a plasma generator, a condenser, a recycle gas loop, a liquid loop, and a pump.

The present invention discloses a non-thermal plasma treatment of metal powders in order to improve their processability by additive manufacturing (AM). The invention consists in bonding primary particles constituted of metals or metal alloys to a plurality of secondary particles constituted of metals, metal alloys, ceramics or polymers by the mean of a non-thermal plasma treatment. The primary particles have a larger mean diameter than the secondary. Both particles are injected through a non-thermal plasma glow discharge and/or in its afterglow region (region downstream the plasma discharge) where their surfaces are cleaned by removing contaminants and/or oxide layer and activated to react between each other. The functionalized metal powders are then collected and afterwards processed by AM leading to high quality parts. The functionalized metal powders produced by this plasma treatment improve the processability of metal by AM. Indeed, decreasing the reflectivity, removing contaminant and oxide layer, enhancing the isotropic solidification of melted materials and decreasing the sintering temperature enhance the efficiency of powder based AM processes.
