Abstract: 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.

Abstract: 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.

Abstract: The present disclosure generally relates to an alkaline electrochemical cell comprising an additive for improved discharge performance. The additive is a finely dispersed superabsorbent material comprising particles having a substantially uniform shape and a small particle size relative to typical materials used in alkaline cells. The superabsorbent material results in enhanced discharge performance of the alkaline cell by increasing access of zinc to the electrolyte.

Abstract: Alkaline electrochemical cells having extended service life and acceptable gassing and corrosion properties are disclosed. An amphoteric surfactant can be incorporated into the gelled anode mixture of an alkaline electrochemical cell, optionally with an organic phosphate ester surfactant or a sulfonic acid type organic surfactant or both. Zinc particles having a defined distribution of particle sizes can also be incorporated into a zinc anode. The electrolyte included, in the anode mixture can have a reduced hydroxide concentration.

Abstract: 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 containing a highly crosslinked polyacrylic acid gelling agent that enables the benefits associated with an electrolyte having a relatively low hydroxide (e.g., potassium hydroxide) content, such as enhanced cell discharge performance, to be achieved, while avoiding the problems commonly associated with electrolytes having relatively low hydroxide content (e.g., an unacceptable level of cell gassing during discharge and/or a negative impact on discharge performance under certain load conditions including, for example, continuous load conditions).
