Abstract
A cylindrical alkaline electrochemical cell is disclosed that includes a gel free anode. The anode includes a free flowing zinc powder with a preassembly tap density between 1.6 g/cc and 2.9 g/cc. In one embodiment, zinc powder with the desired tap density may be obtained by mixing zinc agglomerates with zinc flakes.
