Cable-type secondary battery

摘要

Provided is a cable-type secondary battery extending longitudinally including a lithium ion supplying core comprising an electrolyte, an inner electrode support of a hollow structure formed to surround an outer surface of the lithium ion supplying core, an inner electrode formed on a surface of the inner electrode support and including an inner current collector and an inner electrode active material, a separation layer formed to surround an outer surface of the inner electrode to prevent a short circuit between electrodes, and an outer electrode formed to surround an outer surface of the separation layer and including an outer electrode active material layer and an outer current collector.

1. A cable-type secondary battery extending longitudinally, comprising:
an inner electrode support having a substantially cylindrical, hollow structure; a lithium ion supplying core comprising an electrolyte and being disposed within the substantially cylindrical, hollow structure of the inner electrode support; an inner electrode formed on a surface of the inner electrode support, and including an inner current collector and an inner electrode active material layer; a separation layer formed to surround an outer surface of the inner electrode to prevent a short circuit between electrodes; and an outer electrode formed to surround an outer surface of the separation layer, and including an outer electrode active material layer and an outer current collector.
