Patent ID: 7846584

Claim:
A cathode for a battery, consisting of: (a) cathode active material particles; (b) metal hydroxide particles having a specific surface area of between 2.5 m 2 /g and 100 m 2 /g, as a cathode additive; (c) a conductive agent; and (d) a binder, wherein the metal hydroxide particles in the cathode are present in an amount of greater than 0 wt% and less than 10 wt%, and the cathode active material particles and the metal hydroxide particles in the cathode are a uniform mixture with each other, and wherein the metal hydroxide is Al(OH) 3 having an average particle size of 0.8 μm to 8 μm, or Mg(OH) 2 having an average particle size of 1.0 μm to 9 μm.
