    摘要： The present invention relates to a cooling structure of a lithium ion secondary battery system. The cooling structure of a lithium ion secondary battery system according to the present invention provides cooling channels for lithium battery unit cells accommodated by a laterally partitioned arrangement of main frames, each having a heat radiation part and lattice-shaped paths, and partitioning frames, and allows air, blown by a cooling fan, to cool the lithium battery unit cells while passing through the cooling channels and the lattice-shaped paths. Each of the main frames has a pair of passage slots formed in both sides thereof to allow the air blown by the cooling fan to be directly blown to each accommodated lithium battery unit cell, thus forming each secondary cooling channel communicating with the pair of passage slots.

    摘要： Disclosed is a safety apparatus for responding to a battery short-circuit, and more particularly a safety apparatus for use in the event of a short-circuited of a high power battery, in which a PTC function is integrated into a tab of a high power battery. The safety apparatus for responding to a short-circuit of a high power battery comprises a casing, a battery part including a first electrode plate, a separator, and a second electrode plate arranged in that order and disposed inside the casing, a first tab connected to one of four edges of the first electrode plate via a first tab welding part and protruding from the casing, and a second tab connected to one of four edges of the second electrode plate via a second tab welding part and protruding from the casing, wherein a portion of the first tab ruptures when the first tab and the second tab are short-circuited, thus preventing the first electrode plate and the second electrode plate from being short-circuited.
