Cathode for an electrochemical cell including at least one cathode additive

A battery comprising:

• a housing;
• an anode;
• a cathode, the cathode comprising:
• an electrochemically active cathode material;
• and,
• at least one cathode additive, wherein the at least one cathode additive is a boronic acid, an amine oxide, a phosphine oxide, a sulfoxide, a sulfone or a sultaine,
• and the at least one cathode additive comprises at least one hydrocarbon tail group bound to the boron atom of the boronic acid, the nitrogen atom of the amine oxide, the phosphorus atom of the phosphine oxide, the sulfur atom of the sulfoxide, the sulfur atom of the sulfone, or the nitrogen atom of the sultaine;
• a separator between the anode and the cathode;
• and
• an electrolyte;
• wherein the electrochemically active cathode material comprises a manganese electrochemically active material and a nickel electrochemically active material,
• wherein the manganese electrochemically active material is chosen from one or more in the group of manganese oxide, manganese dioxide, electrolytic manganese dioxide (EMD), chemical manganese dioxide (CMD), high power electrolytic manganese dioxide (HP EMD), lambda manganese dioxide, gamma manganese dioxide, beta manganese dioxide, and mixtures thereof;
• and
• the nickel electrochemically active material is chosen from one or more in the group of nickel oxide, nickel oxyhydroxide, cobalt oxyhydroxide-coated nickel oxyhydroxide, delithiated layered lithium nickel oxide, partially delithiated layered nickel oxide, beta-nickel oxyhydroxide, gamma-nickel oxyhydroxide, intergrowths of beta-nickel oxyhydroxide, intergrowths of gamma-nickel oxyhydroxide, intergrowths of beta-nickel oxyhydroxide and gamma-nickel oxyhydroxide, cobalt oxyhydroxide-coated beta-nickel oxyhydroxide, cobalt oxyhydroxide-coated gamma-nickel oxyhydroxide, cobalt oxyhydroxide-coated intergrowths of beta-nickel oxyhydroxide and gamma-nickel oxyhydroxide, and mixtures thereof.
