Title
(EN) SEPARATOR FOR ELECTROCHEMICAL APPARATUS, ELECTROCHEMICAL APPARATUS, AND ELECTRONIC APPARATUS
(FR) SÉPARATEUR DESTINÉ À UN APPAREIL ÉLECTROCHIMIQUE, APPAREIL ÉLECTROCHIMIQUE ET APPAREIL ÉLECTRONIQUE
(ZH) 一种电化学装置用隔板、电化学装置及电子装置
Abstract
(EN) A separator for an electrochemical apparatus, an electrochemical apparatus, and an electronic apparatus. The separator for an electrochemical apparatus has ion insulating properties, and comprises an intermediate layer and a packaging layer. The packaging layer is located on the upper and lower surfaces of the intermediate layer. The temperature at which the packaging layer begins to soften is at least 10°C lower than the temperature at which the intermediate layer begins to soften. The separator of the present application can ensure the reliability of ion insulation and packaging by means of stacking at least three layers of composite films.
(FR) L'invention concerne un séparateur destiné à un appareil électrochimique, un appareil électrochimique et un appareil électronique. Le séparateur destiné à un appareil électrochimique présente des propriétés d'isolation ionique, et comprend une couche intermédiaire et une couche d'encapsulation. La couche d'encapsulation est située sur les surfaces supérieure et inférieure de la couche intermédiaire. La température de début de ramollissement de la couche d'encapsulation est d'au moins 10 °C inférieure à celle de la couche intermédiaire. Le séparateur selon la présente invention permet d'assurer la fiabilité de l'isolation et de l'encapsulation d'ions au moyen de l'empilement d'au moins trois couches de films composites.
(ZH) 一种电化学装置用隔板、电化学装置及电子装置,电化学装置用隔板具有离子绝缘性,包括中间层和封装层,封装层位于中间层的上下两个表面上;封装层开始软化的温度比中间层开始软化的温度至少低10℃。本申请的隔板通过至少三层复合膜叠加,可以保证离子绝缘和封装的可靠性。
