Silicon For Batteries

Silicon metal has massive potential for improving standard lithium-ion (li-ion) battery performance
Incorporating silicon, rather than graphite into the battery anode, can massively enhance battery efficiency. Innovations surrounding silicon anode technology is promising.

The implications for using silicon in batteries are expansive, with faster charge times (up to 10x the current speed), charges which deplete slower, and more substantial overall charges providing ample opportunity for growth in energy storage and related industries.

The PUREVAP™ Quartz Reduction Reactor (QRR) Project has successfully produced transformed and purified quartz into high purity silicon metal (4N+ Si) in one step. The reactor would enable the low-cost transformation of melted silicon metal into spherical nanopowders and nanowires.

These spherical silicon metal nano-powders will allow the manufacturing of high-performance lithium-ion batteries using silicon metal anodes. By simplifying and standardizing the process used to convert silicon into nano-sized particles, the market potential of silicon anode batteries (and the products which could potentially utilize them) could be vastly expanded.
