CABLE TYPE RECHARGEABLE BATTERY

摘要

The present invention relates to a cable type rechargeable battery, and more particularly the cable type rechargeable battery of the present invention comprises: inner electrodes comprising at least two cathodes disposed in parallel, each of which has a horizontal cross section of a predetermined shape, extends in the length direction and has an electrolyte layer constituting a pathway for ions formed on the outer surface; an outer electrode constituting an anode, which comprises an anode active material layer that envelops the inner electrode; and a protective covering which is disposed around the outer electrode. The cable type rechargeable battery can freely change shape in that it has a linear structure while at the same time being flexible. The battery rating is high because a plurality of inner electrodes are provided inside the outer electrode which is shaped as a pipe, and hence the contact surface area is increased. Also, it is easy to adjust the capacity balance between the inner electrodes and the outer electrode by adjusting the number of inner electrodes, and short circuiting (shorting) can be prevented since the electrolyte layers are formed on the inner electrodes.
