Patent number: 11335959Abstract: An anode for a lithium or lithium-ion cell, protected with an SEI by pre-treatment in an SEI-formation cell, is stable for cell cycling even in the presence of substantial water in the cell electrolyte. A method for making the protected anode includes forming an SEI on a lithium or lithium-ion electrode by performing multiple charge/discharge cycles on the electrode in a first cell having an SEI formation electrolyte to produce the protected anode. The SEI formation electrolyte includes an ionic liquid having at least one of eight organic cations.Type: GrantFiled: July 31, 2019Date of Patent: May 17, 2022Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.Inventors: Nikhilendra Singh, Timothy S.
