Abstract
Methods of forming an electrochemical cell using a non-inert gas are disclosed. Exemplary methods include providing a non-inert gas before and/or after at least one charge and/or discharge cycle. The non-inert gas can facilitate formation of a solid electrolyte interphase (SEI). Further examples of the disclosure relate to methods of forming an electrochemical cell or portion thereof by electrospraying a solution including polymeric material. Such methods potentially eliminate a step of compressing the cell at a pressure beyond 100 MPa and prolong the cycle life while preventing a fire hazard.
