A core laminator of an adhesive laminate core manufacturing apparatus includes a heating unit heating an adhesive interposed between laminar members to integrate the laminar members to form a laminate core, a pinch unit rotatably provided at a lower side of the heating unit which applies a lateral pressure to the laminate core, a squeeze unit including a cylinder rotatably provided at an upper side of the heating unit and a squeezer fixed in the cylinder to align the laminar members in a straight line, a guide provided in the heating unit for guiding a movement of the laminar members, and a driving unit for selectively rotating the pinch unit and the squeeze unit.

Adhesive laminate core manufacturing apparatus and core laminator therefor

A lithium ion secondary battery is provided. The lithium ion secondary battery generally comprises an electrode assembly, a container for accommodating the electrode assembly; and an electrolyte. The electrode assembly comprises two electrodes having opposite polarities and a separator. The separator comprises a porous membrane comprising clusters of ceramic particles. The porous membrane is formed by bonding the particle clusters with a binder. Each particle cluster is formed either by sintering or by dissolving and re-crystallizing all or a portion of the ceramic particles. The ceramic particles comprise a ceramic material having a band gap. Each particle cluster may have the shape of a grape bunch or a lamina, and may be formed by laminating scale or flake shaped ceramic particles.
