Porous alumina powder for lithium ion battery, battery diaphragm, battery and electric equipment
The invention provides porous alumina powder for a lithium ion battery, a battery diaphragm, a battery and electric equipment, and relates to the technical field of battery materials. The porous alumina powder comprises at least not less than 50% of alumina particles having a quadrangular structure in morphology, at most not more than 1% of alumina particles having a spherical structure in morphology, and at most not more than 5% of alumina particles having a needle-shaped structure and a sheet structure in morphology. The ratio of the edge length to the diagonal length of the bottom surface of the aluminum oxide particle with the quadrangular prism structure is 1: (0.5-5). The invention further provides a battery diaphragm, a battery and electric equipment based on the porous aluminum oxide. The porous aluminum oxide provided by the invention is beneficial to optimizing the electrolyte wettability of the polymer diaphragm, so that the electrolyte diffusion radius of the diaphragm is obviously improved.
本发明提供一种用于锂离子电池的多孔氧化铝粉末及电池隔膜、电池、用电设备，涉及电池材料技术领域，所述多孔氧化铝粉末中包括形貌为四棱柱结构的氧化铝颗粒的量至少不低于50%、且形貌为球形结构的氧化铝颗粒的量至多不高于1%、形貌为针形结构和片状结构的氧化铝颗粒的量至多不高于5%；形貌为四棱柱结构的氧化铝颗粒的棱长和底面的对角线长之比为1：（0.5~5）。本申请还提供基于该多孔氧化铝的电池隔膜、电池、用电设备。本申请提供的多孔氧化铝有利于优化聚合物隔膜的电解液浸润性，使隔膜的电解液扩散半径明显提高。
