Rock Tech Lithium joins the European Battery Alliance

VANCOUVER, May 11, 2022 - Rock Tech Lithium Inc. (the "Company" or "Rock Tech") is pleased to announce it is joining the European Battery Alliance (the "EBA"). Maroš Šef?ovi?, Vice President of the European Commission, launched the interest group in 2017 to make Europe a global leader in sustainable battery production and use. The EBA is comprised of around 700 private companies and government institutions. Members include Albemarle, an American lithium producer, BASF, a German producer of cathodes for rechargeable batteries, and the Fraunhofer Institute, among others.

The EBA's goal is to ensure clean, non-polluting traffic in Europe with environmentally friendly vehicles and more sustainable technological solutions. This goal is to be achieved by creating a competitive and sustainable value chain for battery cell manufacturing in Europe. The EBA expects the corresponding market to grow to a volume of €250 billion by 2025.

Commenting on Rock Tech Lithium joining the EBA, Dirk Harbecke, Chairman of the Company, said, "For us, the EBA represents a fantastic platform to further expand our network of companies in the battery value chain, academics and policy makers. We look forward to exchanging ideas with the other members."

Rock Tech Lithium (TSX-V: RCK) (OTCQX: RCKTF) (FWB: RJIB) (WKN: A1XF0V) is a cleantech company with operations in Canada and Germany that aims to supply the automotive industry with high-quality, "made in Germany" lithium hydroxide. As early as 2024, Rock Tech intends to commission Europe's first lithium converter with a production capacity of 24,000 tonnes per year. This is equivalent to the volume needed to equip around 500,000 electric cars with lithium-ion batteries.

Rock Tech owns the Georgia Lake Project in Ontario, Canada. The company has set itself the goal of creating the world's first closed-loop for lithium, thus closing the raw material gap on the road to clean mobility. As early as 2030, around 50 percent of the raw materials used are expected to come from the recycling of batteries.
