Abstract
Secondary metal ion batteries are fabricated using a working electrolyte that is substantially incompatible with the anode material. This is accomplished by forming an SEI on the anode material at least in part using a compatible (i.e., SEI developing) electrolyte, and including a substantially incompatible (non-SEI forming) composition as the working electrolyte.
