Rechargeable zinc cell with longitudinally-folded separator

A method of constructing a rechargeable zinc cell with a longitudinally-folded separator, said method comprising the steps of:

• obtaining a zinc negative electrode, a positive electrode, an electrolyte and a separator, wherein said separator comprises two wicking layers with a microporous layer disposed therebetween;
• placing said zinc negative electrode in contact with one of said two wicking layers of said separator, wherein a first side of said zinc negative electrode is fully covered by said separator;
• folding said separator longitudinally around a long edge of said zinc negative electrode;
• placing said positive electrode on said folded separator in contact with the other of said two wicking layers;
• and
• rolling said zinc negative electrode, said positive electrode and said separator into a jelly roll structure, wherein said jelly roll structure comprises a negative terminal in electrical communication with said zinc negative electrode and a positive terminal in electrical communication with said positive electrode.

A rechargeable zinc cell with a longitudinally-folded separator, said rechargeable zinc cell comprising:

• a zinc electrode comprising two ends and two long edges;
• a separator folded along one of said two long edges of said zinc electrode, wherein said separator covers both sides of said zinc electrode;
• and
• an electrolyte comprising KAcet.
