Cheaper approach makes Si EV battery viable, Canada's HPQ says

With leading car makers eyeing extra silicon in electric vehicle (EV) batteries, a Canadian company claims to be getting close to making that commercially viable with its breakthrough process.

HPQ Silicon Resources Inc, of Montreal said on Tuesday June 22 it had solidified its position with a C$4.4 million ($3.58 million) equity increase, while it nears the testing phase of its patent-pending process to go straight to battery-grade silicon from quartz. This would be used in lithium-ion batteries.
HPQ announced 12 days earlier that it would begin test production by the fourth quarter of this year - previously delayed by factors that included the pandemic, it said.
Bernard Tourillon, chairman, president, and chief executive of HPQ told Fastmarkets that his company, uniquely in North America, will go straight to high-purity silicon from quartz.
