Possible it is Tesla. From the ann. Li-ion batteries put out on 17/2/16- page 1 "further tests on Vittangi ore underway which include graphene and graphene/silicon composite anodes."
From Silican Valley Business Journal 19/6/15......."Tesla has made another important step toward cheaper and more powerful batteries. The Palo Alto based electric car company entered into an exclusive partnership on wednesday with Jeff Dahn, a leading battery researcher known for his work on lithium-ion batteries. The financial terms of the deal were not disclosed but CEO Elon Musk's company will sponsor Dahn's research efforts in return for his help solving Tesla's battery issues.....Dahn is a professor at Dalhouisie University in Nova Scotia and will start work with Tesla following a current project with 3M Co.
He patented a nickel-cobalt-manganese chemistry for battery cathodes, which is now commonly used, and he is the leading researcher on why lithium-ion batteries fail, according to the Wall st. Journal. He also specializes in silicon anodes, an alternative to graphite.

Tesla's latest most powerful battery pack is the P90 (90kwh) upgraded from the P85 by the use of a silicon/graphite composite anode.
So Professor Dahn's silicon expertise is bearing fruit and maybe just maybe there is a Talga/Tesla connection.
