Abstract: The present invention relates to a single crystal ingot growing apparatus capable of precisely controlling an Ox volatilization on a silicon melt solution surface by uniformly forming a flow velocity of an inert gas flowing along the silicon melt solution surface.

Abstract: The present disclosure discloses a secondary battery and a manufacturing method thereof. According to the present disclosure, the influence of heat generated at a welding spot between an electrode tab and an electrode lead on the performance of a secondary battery may be minimized. Accordingly, in the design of a large capacity secondary battery, the battery performance may be close to an ideal condition.
