Abstract
A method for forming a gelled anode in which a powdered anode metal is mixed with means for maintaining a uniform mixture of the powdered metal and a gelling agent, the gelling agent is added, and the mixture is fed into an aqueous electrolyte in the cell whereupon a gel is formed in situ.
Claims11
A method for forming a cell having a substantially homogeneously gelled anode comprising the steps of mixing a powdered anode metal with a gelling agent, and with liquid means other than the gelling agent for maintaining, during subsequent gelling, a homogeneous mixture of the powdered metal, said gelling agent and a liquid, said gelling agent being capable of gelling the powdered anode metal when in the presence of an aqueous electrolyte solution;
- and then dispensing the resulting ungelled mixture into an electrolyte solution in an electrochemical cell, whereby the substantially homogeneously gelled anode is formed in situ.
A method for forming a cell having a substantially homogeneously gelled anode comprising the steps of mixing a powdered anode metal with a gelling agent, and with a polyhydric alcohol for maintaining, during subsequent gelling, a homogeneous mixture of the powdered metal, said gelling agent and a liquid, said gelling agent being capable of gelling the powdered anode metal when in the presence of an aqueous electrolyte solution;
- and then dispensing the resulting ungelled mixture into an electrolyte solution in an electrochemical cell, whereby the substantially homogeneously gelled anode is formed in situ.
