Title:
Cable type rechargeable battery
Document Type and Number:
Japanese Patent JP6247668
Kind Code:
B2
Abstract:
The present invention relates to 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 inner electrode, comprising an open-structured inner current collector surrounding the outer surface of the core for supplying lithium ions, an inner electrode active material layer formed on the surface of the inner current collector, and a first electrolyte-absorbing layer formed on the outer surface of the inner electrode active material layer; a separation layer surrounding the outer surface of the inner electrode to prevent a short circuit between electrodes; a second electrolyte-absorbing layer formed on the surface of the separator; and an outer electrode surrounding the outer surface of the second electrolyte-absorbing layer and comprising an outer electrode active material layer and an outer current collector. In accordance with the present invention, the core for supplying lithium ions, which comprises an electrolyte, is disposed in the inner electrode having an open structure, and the inner electrode and the separation layer each have an electrolyte-absorbing layer on the outer surface thereof, from which the electrolyte of the core for supplying lithium ions can be contained in the electrolyte-absorbing layer to be easily penetrated into an electrode active material, thereby facilitating the supply and exchange of lithium ions.
