CABLE-TYPE SECONDARY BATTERY COMBINED WITH SIGNAL WIRE
The present disclosure discloses a cable-type secondary battery combined with a signal wire, including: a cable-type secondary battery extending in a lengthwise direction and having a hollow interior; a signal wire unit inserted into the cable-type secondary battery and extending in the lengthwise direction of the cable; and a cable sheath covering the cable-type secondary battery.
1 . A cable-type secondary battery combined with a signal wire, comprising:
a cable-type secondary battery extending in a lengthwise direction and having a hollow interior structure;
a signal wire unit inserted into the cable-type secondary battery and extending in the lengthwise direction of a cable; and
a cable sheath covering an outside of the cable-type secondary battery.
2 . The cable-type secondary battery combined with a signal wire of claim 1 , wherein the signal wire unit is formed of an optical cable.
3 . The cable-type secondary battery combined with a signal wire of claim 2 , wherein the optical cable is a tight-buffered optical cable, a loose tube-type optical cable, or a slot-type optical cable.
4 . The cable-type secondary battery combined with a signal wire of claim 2 , wherein the signal wire unit is formed of a conductor cable.
5 . The cable-type secondary battery combined with a signal wire of claim 1 , wherein the cable-type secondary battery comprises:
a hollow anode layer;
a separator surrounding the anode layer; and
a cathode layer surrounding the separator.
6 . The cable-type secondary battery combined with a signal wire of claim 5 , wherein the anode layer is formed by spirally winding a copper wire coated with a negative electrode active material so as to extend in the lengthwise direction of the cable.
7 . The cable-type secondary battery combined with a signal wire of claim 5 , wherein the cathode layer is formed by spirally winding a conductor strip coated with a positive electrode active material so as to extend in the lengthwise direction of the cable.
8 . The cable-type secondary battery combined with a signal wire of claim 1 , wherein the cable-type secondary battery is a lithium secondary battery.
