Abstract
Official abstract text for this publication.
The present invention relates to an anode for a cable-type secondary battery, more specifically an anode for a cable-type secondary battery, comprising a spiral electrode consisting of at least two wire-type electrodes which are spirally twisted with each other, each of the wire-type electrodes comprising a wire-type current collector, an anode active material layer formed by coating on the outer surface of the wire-type current collector, and a polymer resin layer formed by coating on the outer surface of the anode active material layer; and a cable-type secondary battery comprising the anode. The anode for a cable-type secondary battery according to the present invention comprises a polymer resin layer formed by coating on the outer surface of an anode active material layer, thereby preventing the release of the anode active material layer from a wire-type current collector and eventually preventing the deterioration of battery performances.
First claim
Opening claim text (preview).
What is claimed is: 1. A cable-type secondary battery having a horizontal cross section of a predetermined shape and extending longitudinally, comprising: a core for supplying lithium ions, which comprises an electrolyte; an anode surrounding the outer surface of the core for supplying lithium ions; a separation layer surrounding the outer surface of the anode, thereby preventing a short circuit between electrodes; a cathode having a cathode active material layer surrounding the ou…
