A gelled anode for an alkaline electrochemical cell contains zinc-based particles, an alkaline electrolyte, a gelling agent, and two or more additives selected from the group consisting of an alkali metal hydroxide, an organic phosphate ester surfactant, a metal oxide, and tin, which as reduced cell gassing properties relative to cells lacking such additives.

Alkaline cell with improved discharge efficiency

A negative electrode for an alkaline battery cell which includes zinc-based particles, wherein less than 20% of the zinc-based particles, by weight relative to the total zinc in the electrode, have a particle size of greater than about 150 micrometers, is provided. An alkaline electrochemical cell that includes the negative electrode and a method for reducing the gassing of the electrochemical cell is also provided.

Alkaline cell with improved reliability and discharge performance

The present disclosure relates generally to an alkaline electrochemical cell, such as a battery, and in particular to an improved gelled anode suitable for use therein. More specifically, the present disclosure relates to a gelled anode that improves anode discharge efficiency by adjusting physical properties such as apparent density.

Alkaline cell with improved high rate capacity

Alkaline cell with improved high rate capability

The present disclosure is directed to a primary electrochemical cell having an improved discharge performance, and/or improved reliability under physical abuse and/or partial discharge. More particularly, the present disclosure is directed to such a primary cell that comprises an improved cathode material comprising iron disulfide and a select pH-modifier and an improved non-aqueous electrolyte that comprises a solvent, a salt, pH-modifiers, and selected organic or inorganic additives, which improve cell stability and discharge performance.
