1. A method of forming a battery, the method comprising:
forming a battery comprising a cathode, an electrolyte, and an anode, wherein said one or both of said cathode and said anode contain one or more functional aliphatic and/or aromatic amine compounds as electrode additives to reduce gas generation in said battery; wherein said one or both of said cathode and said anode is formed using, at least, the following steps:
an electrode material is mixed to create a slurry;
said one or more functional aliphatic and/or aromatic amine compounds is added to said slurry;
said slurry is coated on metal foil; and
the coated metal foil is dried;
further wherein said one or more functional aliphatic and/or aromatic amine compounds are incorporated into said cathode where the cathode electrode material is Lithium Nickel Cobalt Aluminum Oxide (LiNixCoyAlzO2, x+y+z=1); Lithium Nickel Cobalt Manganese Oxide (LiNiaCobMncO2, a+b+c=1); or Lithium Nickel Cobalt Manganese Aluminum Oxide (Li[NipCOqMnrAls]O2, p+q+r+s=1);
wherein said anode is a Si-dominant anode comprising more than 50% silicon by weight; and
wherein said one or more functional aliphatic and/or aromatic amine compounds is Hexakis(allylamino)cyclotriphosphazene (HALCPZ).
