That material may soon be even better, thanks to Novonix’s recent return to its research roots. In October 2018, the company signed a partnership with Dalhousie University to sponsor one of its battery research groups. That sponsorship has already begun to pay off, as Novonix has filed its first patent for silicon-infused graphite developed by the Dalhousie team.
“For years and years, companies have been trying to put silicon into graphite to give the battery more capacity,” explained St Baker. “But the problem is the silicon expands and contracts and damages the graphite and [shortens] battery life. So this has been an ongoing problem that the industry has been dealing with. The guys working for us in Dalhousie have managed to get the silicon inside the graphite particles. Not only do they get the silicon inside the particles, but they do it in a manner which is very cheap.”
The results of that research should come to light within the next few months. In the meantime, Novonix is in the process of filing a second patent that’s focused on battery cathodes rather than anodes.
a friend found this info >>>>>> very interesting in particular these technologies mentioned / has a connection to both tesla and novonix or it so seems ????????????????? what do you guys think ???

Tesla files lithium-ion pouch cell patent aimed at the EV and energy storage markets Mon, 01/06/2020 - 10:31 -- Paul Crompton
Tesla Motors Canada has filed a patent for a lithium-ion pouch cell containing ‘fewer operative, electrolyte additives’ with the potential to be used in energy storage applications including vehicle and grid-storage— Tesla’s key markets.
The new technology using a nickel manganese cobalt (NMC) chemistry was filed under the title ‘Dioxazolones and nitrile sulfites as electrolyte additives for lithium-ion batteries’.
