Abstract
The invention includes a flexible pasted anode comprising a flexible current collector and a paste comprising zinc particles and at least one block copolymer binder, wherein said flexible current collector and said paste form a unit. The invention includes primary cell comprising the flexible pasted anode, a cathode, and electrolyte. The invention also includes an anode paste comprising zinc particles and at least one block copolymer, wherein said paste is suitable for use in an anode. The invention further includes a method of manufacturing zinc anode comprising combining zinc powder, block copolymer, and solvent to form a paste, depositing the paste onto a current collector, and drying the wet pasted anode, and a method of manufacturing a primary cell comprising: forming a flexible pasted zinc anode to form a convoluted pasted zinc anode, inserting said convoluted pasted zinc anode into a cell container, and filling said container with electrolyte.
