Tesla's New Battery Patent
Tesla has applied for a patent on new electrolyte solutions for new lithium metal or anode-free battery cells. Battery technology has been rapidly improving. As costs have declined, energy density has increased, and there is every reason to believe that this trend will continue.
Tesla's current batteries offer great advantages when it comes to energy density and costs, but it needs improvements when it comes to longevity.
Tesla’s battery research partner, Jeff Dahn and his team at Dalhousie University claim that their new electrolyte would help improve just that:
“Provided are electrolyte solutions including both lithium difluoro(oxalato)borate and lithium tetrafluoroborate and a solvent component for use in lithium metal or anode-free rechargeable battery cell and methods of using the electrolyte solutions to improve capacity retention of the battery cells. Also provided are rechargeable battery systems including lithium metal or anode-free battery cell and electrolyte solutions including both lithium difluoro(oxalato)borate and lithium tetrafluoroborate and a solvent component. The systems described herein exhibit improved capacity retention.”
