TOKYO, Feb 9 (Reuters) - Japan's Panasonic Energy, a supplier for Tesla's electric vehicles, said on Friday it has struck a graphite supply agreement for its U.S. battery plants with Australian materials company Novonix.

The off-take agreement allows the battery unit of Panasonic to procure 10,000 tons of graphite from Novonix’s North American plants including in Tennessee over four years, and the shipments are scheduled to start in 2025, it said. (Reporting by Kantaro Komiya; Editing by Chris Reese)
