Abstract

Disclosed is a method for efficiently producing a plurality of fiber electrodes simultaneously from a plurality of fibers, which takes advantage of the advantages that fiber electrodes conventionally have. The method for producing fiber electrodes has steps (2,2a) for opening a bundle of fibrous material, steps (3,4,5) for obtaining a fiber cathode or a fiber anode by means of forming a cathode active material coat layer or an anode active material coat layer on each monofilament obtained by means of opening, and steps (6,6a) for forming a separator coat layer on the abovementioned fiber cathode or fiber anode.

Description

Technical field [0001] The invention involves fiber electrodes suitable for batteries or capacitors and its fiber batteries, as well as manufacturing equipment for the fiber electrode and fiber battery.The fiber battery of the present invention can be suitable for secondary batteries with aquatic solution as an electrolyte, specifically nickel-hydrogen battery or nickel-cadmium-cadmium battery, nickel-iron battery, nickel-zinc battery, or lead battery.The fiber battery of the present invention can also be suitable for non -hydrolytic secondary batteries, air batteries or capacitors represented by lithium ion batteries. Background technique [0002] The existing aquatic solution is used as a secondary battery of the electrolyte, with positive plates, partitions, and negative plates.Alkaline secondary batteries usually use harsh potassium or water solution of lithium hydroxide to dissolve as electrolytic solution; lead battery is usually used as electrolytic solution as electrolyti...
