An alkaline electrochemical cell includes a cathode, an anode which includes an anode active material, and a non-conductive separator disposed between the cathode and the anode, wherein from about 20% to about 50% by weight of the anode active material relative to a total amount of anode active material has a particle size of less than about 75 μm, and wherein the separator includes a unitary, cylindrical configuration having an open end, a side wall, and integrally formed closed end disposed distally to the open end.

Alkaline electrochemical cell with improved anode and separator components

A rechargeable hearing aid battery includes a stack of active materials forming a core, a two-part casing including an inner casing and an outer casing, and a grommet. The grommet includes an opening through which a conductive tab extends. The conductive tab is configured to electrically connect an electrode of the core to one of the outer casing and the inner casing. The grommet is configured to insulate a portion of the tab from the core and to insulate the core from one of the outer casing and the inner casing. Furthermore, the grommet is configured to separate the inner casing from the outer casing and to seal a gap formed between the inner and outer casing.
