Abstract

An active electrode composition comprising an active electrode material and a binder where the binder comprises a monosaccharide, a disaccharide, a pectin or a molasses. Preferably, the active electrode material is nickel hydroxide.

Claims

1. An active composition for a positive electrode of an alkaline electrochemical cell, comprising:

a nickel hydroxide material; and

a binder comprising a molasses.

2. The active composition of claim 1, wherein said binder is between about 0.1 and 2.0 weight percent of said active material composition.

3. A positive electrode for an alkaline electrochemical cell, comprising:

an active composition including;

a nickel hydroxide material; and

a binder comprising a molasses.

4. The active composition of claim 3, wherein said binder is between about 0.1 and 2.0 weight percent of said active material composition.

5. An alkaline electrochemical cell, comprising:

at least one positive electrode;

at least one negative electrode; and

an alkaline electrolyte, said positive electrode having an active material composition including a nickel hydroxide material and a binder comprising a molasses.

6. The electrochemical cell of claim 5, wherein said negative electrode comprises a hydrogen storage active material.
