<p>In the production of electrolytic manganese dioxide, the anodically deposted product is removed by cathodically polarizing the electrode, possibly assisted by impact or vibration. Typically, the current is reversed periodically when the deposit is about 100-1500 //c thick, shortly after current reversal the product peels off as flake-like particles which can easily be ground to form a battery de-polarizer. An apparatus for carrying out the removal of the desired product comprises an electrolytic cell (1) including a plurality of electrodes (4) (5) and means (10) (11) for reversing the polarity of the electrodes at selected times.</p> |
