Claim 13:
14. A method of forming an energy storage device, the method comprising:
forming an energy storage device comprising a cathode, an electrolyte composition, and an anode;
wherein said one or more of said cathode or said anode and/or said electrolyte composition comprise an additive compound;
said additive compound comprising an asymmetrical alkylsulfonyl imide or alkylene sulfonylimide salt;
wherein said one or both of said cathode and said anode is formed using, at least, the following steps:
said electrode material is mixed to create a slurry;
said electrolyte composition is added to said slurry;
said slurry is coated on metal foil; and

the coated metal foil is dried salt; and
wherein the additive compound is of formula (Ia) or (Ib):, wherein X is Na, K, Rb, Cs, Fr, Mg, Ca, Zn or Al;
R1 and R2 are different and are selected from the group consisting of H, OH, alkylene, alkoxy, alkenyl, alkenylene, alkynyl, alkynylene, cycloalkyl, cycloalkylene, aryl, arylene, heteroaryl, heteroalkyl, heteroalkylene, heterocycloalkyl, and heterocycloalkylene, which may be also further optionally substituted.
