Asahi Kasei chooses Ontario to build Canada’s first EV battery separator plant


Invest Ontario welcomes transformative investment that strengthens province’s EV battery supply chain

PORT COLBORNE, Ontario, May 14, 2024 – Invest Ontario welcomes a transformative investment by Asahi Kasei to build Canada’s first industrial-scale electric vehicle (EV) battery separator plant in Port Colborne, Ontario, further bolstering the province’s EV battery supply chain and cementing its leadership in the global EV transition.

This expansion marks Asahi Kasei’s first major investment in Ontario, which will help the company meet the growing demand in North America for lithium-ion battery separators used in EVs, while addressing an important gap in Ontario’s EV battery supply chain.

The Tokyo-based multinational chemicals company is investing approximately $1.6 billion in constructing the facility. With growth anticipated in the North American EV market, Asahi Kasei expects to make additional multi-billion-dollar investments through multiple phases. Details regarding direct jobs created by this investment are currently being finalized and will be announced at a later date.

Asahi Kasei is excited to bring its Hipore™ battery separator manufacturing facility to Port Colborne, Ontario. With its commitment to EV and battery supply chains, and its proximity to key automotive and other partners, Canada was the ideal choice for our North American expansion.

Koshiro Kudo

President & Representative Director of Asahi Kasei Corporation

Today’s announcement is more good news for Ontario’s world-leading electric vehicle manufacturing sector and the thousands of workers who are benefiting from the billions of investments being made in our province. Asahi Kasei’s investment will bring economic growth and good-paying jobs to workers in Port Colborne and across the Niagara Region. It’s also yet another show of confidence in our government’s ongoing work to build a domestic EV supply chain in Ontario that benefits workers across the province, from critical mineral extraction in the Ring of Fire to battery manufacturing in Port Colborne and everywhere in between.

Hon. Doug Ford

Premier of Ontario

Separators are one of the four key components of lithium-ion battery cells (anodes, cathodes, and electrolytes being the other three). Acting as a physical barrier between the anode and cathode, the separator plays an important role in maintaining thermal stability and safety of the battery cell.

With battery cells and cathodes already being produced in Ontario, this investment will lead the province another step closer to becoming a jurisdiction that can produce every part of the modern EV battery locally.

Over the last four years, Ontario has become the epicentre of Canada’s electric vehicle supply chain, attracting billions in investments by global automakers and suppliers of EV batteries and battery materials. Today, our government is proud to welcome Asahi Kasei as the newest addition to Ontario’s thriving automotive ecosystem. Thank you, Asahi Kasei, for trusting Ontario as a partner in your success.

Hon. Vic Fedeli

Ontario’s Minister of Economic Development, Job Creation and Trade

Canada bet big on electric vehicles, and today, the biggest manufacturers in the world are building them right here in Canada. Asahi Kasei’s investment is another vote of confidence in our auto industry and auto workers. We’re creating good-paying jobs, keeping the air clean, and putting Canada at the forefront of this exciting opportunity.

Rt. Hon. Justin Trudeau

Prime Minister of Canada

In 2023, Ontario welcomed investment projects including EV battery enclosures, motor core components, advanced thermal management systems, as well as micro-LED technologies for vehicle displays, bringing more skilled jobs to the province and further strengthening its auto/EV supply chain.

Asahi Kasei's investment speaks to what companies in the battery supply chain have already realized – that Ontario is a strategic location to develop and manufacture cutting-edge products for the growing EV market in North America. Invest Ontario remains dedicated to partnering with industry leaders and innovators to lead the charge together towards sustainable mobility.
