OAKVILLE— Minister of Innovation, Science and Industry, François-Philippe Champagne announced an investment of $4.1 million towards Oakville-based Polar Sapphire through Sustainable Development Technology Canada.

According to a company statement, this is the second SDTC investment in Polar Sapphire and part of a continuing collaboration that is helping the company produce high-purity alumina (HPA) for use in next-generation solid-state lithium-ion batteries.

Polar Sapphire has stated that it will use the investment to evolve its core process for the manufacture of a different type of HPA, improving the product’s quality and purity while expanding its market. The company employs cutting-edge technology to perform purification at lower temperatures and with less power, reducing the cost and carbon footprint of HPA production.

According to Polar Sapphire, next-generation LIBs will require HPA as a key ingredient. These solid-state LIBs could be a game changer for electric vehicles and many other clean technologies by charging faster, storing more energy, offering greater safety than liquid LIBs and helping propel the shift to a net-zero carbon economy.
