Abstract
Official abstract text for this publication.
A battery includes an air cathode, an anode, an aqueous electrolyte, and a housing, wherein the housing includes one or more air access ports defining a total vent area; the battery exhibits a cell limiting current at 1.15V; a ratio of cell limiting current at 1.15 V to total vent area is greater than about 100 mA/mm 2 ; and the aqueous electrolyte includes an amphoteric fluorosurfactant.
First claim
Opening claim text (preview).
What is claimed is: 1 . A battery comprising an air cathode, an anode, an aqueous electrolyte, and a housing, wherein: the housing comprises one or more air access ports defining a total vent area; the battery exhibits a cell limiting current at 1.15V; a ratio of cell limiting current at 1.15 V to total vent area is greater than about 100 mA/mm 2 ; and the aqueous electrolyte comprises an amphoteric fluorosurfactant. 2 . The battery of claim 1 , wherein the ratio is greater than about 150 mA/mm 2 . 3 . The battery of claim 1 , wherein the ratio is greater than 250 mA/mm 2 . 4 . The battery of claim 1 , wherein the ratio is from about 70 mA/mm 2 to about 1000 mA/mm 2 . 5 . The battery of claim 1 having a nominal diameter of about 8 mm and a nominal height of about 5.4 mm. 6 . The battery of claim 1 having a nominal diameter of about 8 mm and a nominal height of about 3.6 mm. 7 . The battery of claim 1 , wherein the battery has a nominal external volume from about 180 mm 3 to about 270 mm 3 . 8 . The battery of claim 1 , wherein the nominal electrode interfacial area is about 35 mm 2 . 9 . The battery of claim 1 , wherein the total vent area is from about 0.030 mm 2 to about 0.115 mm 2 . 10 . The battery of claim 1 , wherein the cell limiting current at 1.15 V is about 4 mA to about 15 mA. 11 . A battery comprising an air cathode, an anode, an aqueous electrolyte, and a housing, wherein: the housing comprises one or more air access ports defining a total vent area; the battery exhibits a cell limiting current at 0.9V; the battery, when discharged at a current equal to half of the limiting current, maintains voltage of 1.17V or higher through 50% of it's theoretical discharge capacity; and the aqueous electrolyte comprises an amphoteric fluorosurfactant. 12 . The battery of claim 11 having a nominal diameter of about 8 mm and a nominal height of about 5.4 mm. 13 . The battery of claim 11 having a nominal diameter of about 8 mm and a nominal height of about 3.6 mm. 14 . The battery of claim 11 , wherein the total vent area is from about 0.030 mm 2 to about 0.115 mm 2 . 15 . The battery of claim 11 , wherein the cell limiting current at 1.15 V is about 4 mA to about 15 mA. 16 . A battery comprising an air cathode, an anode, an aqueous electrolyte, and a housing, wherein: the housing comprises one or more air access ports defining a total vent area; the battery exhibits a cell limiting current at 0.9V; the battery, when discharged at a current equal to one-third of the limiting current, maintains voltage of 1.20V or higher through 50% of it's theoretical discharge capacity; and the aqueous electrolyte comprises an amphoteric fluorosurfactant. 17 . The battery of claim 16 having a nominal diameter of about 8 mm and a nominal height of about 5.4 mm. 18 . The battery of claim 16 having a nominal diameter of about 8 mm and a nominal height of about 3.6 mm. 19 . The battery of claim 16 , wherein the total vent area is from about 0.030 mm 2 to about 0.115 mm 2 . 20 . The battery of claim 16 , wherein the cell limiting current at 1.15 V is about 4 mA to about 15 mA.
