阅读说明：本技术 隔膜、电极组件、电池及电子装置 (Separator, electrode assembly, battery, and electronic device ) 是由 樊晓贺 魏增斌 于 2020-03-27 设计创作，主要内容包括：一种隔膜(230),包括隔膜基材(30)以及混合涂层(50)。混合涂层(50)设置于所述隔膜基材(30)的表面,混合涂层(50)包括发泡微球(51)以及粘结剂(52)。发泡微球(51)包括核(512)以及包覆核(512)的包覆层(514)；发泡微球(51)的核(512)为受热分解后产生二氧化碳、氮气以及一氧化碳中的至少一种无机气体的发泡剂。另外提供一种包括隔膜(230)的电极组件(20)、电池(100)以及电子装置(200)。(A separator (230) includes a separator substrate (30) and a hybrid coating (50). The mixed coating (50) is arranged on the surface of the diaphragm base material (30), and the mixed coating (50) comprises foaming microspheres (51) and a binder (52). The foamed microsphere (51) comprises a core (512) and a coating layer (514) coating the core (512); the core (512) of the expanded microsphere (51) is a foaming agent which generates at least one inorganic gas of carbon dioxide, nitrogen and carbon monoxide after being heated and decomposed. An electrode assembly (20) including a separator (230), a battery (100), and an electronic device (200) are also provided.)
