PURPOSE: A positive electrode of a lithium thionly battery is provided to improve stability to an internal short circuit in a part where different layers are exposed by a chain of a metal net by not using an insulative tape, but carbon powder, and to improve volume capacity and operation voltage property. CONSTITUTION: A positive electrode of a lithium thionly battery a metal net(20) having a grid structure, a tab(10) in which a terminal is welded to the metal net to be exposed to an outside of the metal net, and a plurality of grooves(11) is formed on an outside, and a carbon layer formed on the outside of the tab and the metal net. Materials forming the carbon layer are filled in the grooves, thereby attaching the carbon layer and the tab. A manufacturing method of the positive electrode comprises a step of preparing the metal net and the tab, a step of welding the tab to the metal net to expose a terminal of the tab from the metal net, and a step of forming the carbon layer on the outside of the metal net and on the tab except the terminal of the tab. |
