Tesla has applied for a patent on new electrolyte solutions for a new lithium metal or anode-free battery cell.
Over the last year, we have been reporting on Tesla’s battery research partner, Jeff Dahn and his team at Dalhousie University, unveiling the impressive results of tests on a new battery cell that could last over 1 million miles in an electric vehicle. The team has been working for Tesla to improve energy density and longevity of battery cells while reducing costs.
But Dahn, who is a pioneer of Li-Ion battery technology, and his team have also been working on next-generation battery technology — beyond improving on current technology.
Last year, we reported on the team patenting an “anode-free lithium-metal cell” for Tesla that they suggested could be the next big thing in battery tech instead of solid-state batteries.
They are still working on the new cells as evidenced by a new patent application Dahn’s team for Tesla’s Canadian research group: “Electrolytes with Lithium Difluoro(oxalato)borate and Lithium Tetrafluoroborate Salts for Lithium-metal and Anode-Free Battery Cells.”
Tesla’s battery offers great advantages when it comes to energy density and costs, but it needs improvements when it comes to longevity.
