Title:
耐高温多層複合リチウムイオン電池セパレータのコーティング装置
Document Type and Number:
Japanese Patent JP6851478
Kind Code:
B2
Abstract:
A heat-resistant multi-layer composite lithium-ion battery separator, and coating device and manufacturing method for same. The battery separator comprises a base membrane (12) having two end faces provided with a coating paste, and the end faces of the base membrane (12) are both adhered with a composite layer via the coating paste. The composite layer comprises one, two, or multiple composite films (13). The composite films (13) are adhered and fixed via the coating paste. The coating device is employed during the manufacturing, and comprises a base membrane uncoiling reel (1), a coating roller (2), a composite film uncoiling mechanism, a heating and drying mechanism, and a coiling reel (6). The coating roller (2) is arranged in a one-to-one correspondence to the composite film uncoiling mechanism, and two sets of the coating roller and the composite film uncoiling mechanism are provided on two sides of the base membrane (12). The composite film uncoiling mechanism comprises a composite film uncoiling reel (3) and a pressing shaft (4), and the composite films (13) are attached to the base membrane (12) after passing through the pressing shaft (4) to form a multi-layer composite separator, and then heated, dried, and shaped to obtain a separator final product. The separator final product has superior heat-resistant stability and a heat-resistant rate of contraction.
