Abstract

PROBLEM TO BE SOLVED: To provide a novel secondary electrochemical cell employing an electrolyte containing one or more (i.e., at least one) charge-carriers, and a positive electrode active material containing one or more (i.e., at least one) charge-carriers, where, in a nascent state of the electrochemical cell, the charge carriers present in the electrolyte differ from the charge carriers present in the positive electrode active material.SOLUTION: The invention provides an electrochemical cell having: a first electrode having an electrode active material containing at least one electrode active material charge-carrier; a second electrode; and an electrolyte containing at least one electrolyte charge-carrier. In a nascent state of the electrochemical cell, the at least one electrolyte charge carrier differs from the at least one electrode active material charge-carrier.
