Patent
·
OSTI ID:5982861
An alkaline/manganese dioxide cell which is repeatedly rechargeable from a deeply discharged state is produced by chemically contacting the manganese dioxide with free negative ions of at least one weak acid that does not, in the conditions prevailing in the cell, form salts with manganese the crystals of which contain water of crystallization. Suitable weak acids are silicic, carbonic, boric, cyanic and acetic acids and hydrogen sulphide.
