We covered Washington Governor Jay Inslee’s visit to the Group 14 Technologies battery plant in Woodinville last year.  Now the Group is getting attention from Porsche, among other funders.  The startup company announced raising $400 million from investors including the Teutonic automaker. According to Reuters, part of those funds will be used to build a second battery materials plant in eastern Washington State.  The company is now valued at over $1 billion, money which will help expand battery materials production for the silicon-lithium cell market. Silicon is a desirable material in batteries, capable of storing more energy than lithium or other metals.  It has a major drawback, though.  In expanding and contracting during charge-discharge cycles, it eventually deteriorates, crumbles, and brings the battery’s usefulness to an end. Dr. Yi Cui of Stanford University has tried various methods over the years to prevent such crumbling.  His firm, Amprius, has developed a silicon nanowire anode that enables a battery with 450 Watt-hour …

Tina Casey, writing in Clean Technica, reflects on the coming changes in the “gasmobile” to EV ratio.  “Somewhere in the outer reaches of talk radio, a ghost stalks the halls, mumbling of light bulbs and plastic bags and electric cars that won’t start in cold weather. Meanwhile, most automakers are not waiting around for the other shoe to drop. They have finally begun pivoting into the sparkling green world of zero emission personal mobility, even those once wedded to the idea of ‘clean diesel,’ and a new battery formula is here to help.” Her article, “Game Over For Gasmobiles: Electric Vehicle Batteries Just Keep On Getting Better,” describes efforts at Group 14, the second of two electric vehicle firms recently visited by Washington Governor Jay Inslee.  The first was Eviation, based in Arlington. SCC55™ Group 14 is reputedly, “The largest manufacturer of lithium-silicon battery materials,” capable of producing 120 tons per year of SCC55™, its patented battery anode material.  SCC55, …
