Porous aluminum oxide, battery diaphragm, battery and electric equipment
The invention provides porous aluminum oxide, a battery diaphragm, a battery and electric equipment, and relates to the technical field of battery materials, the porous aluminum oxide is an aluminum oxide particle with a plurality of mesopores on the surface and/or in the interior; the aluminum oxide particles are quadrangular crystals of which the thickness is not less than 20% of the side length of the bottom surface; the cumulative particle diameter D50 of 50% of particles on the small particle diameter side in the cumulative particle diameter distribution is 0.3-2 [mu] m; the angle of repose of the porous aluminum oxide is 36.0 degrees to 38.5 degrees. The invention further provides a battery diaphragm, a battery and electric equipment based on the porous aluminum oxide. According to the porous alumina provided by the invention, the problem that the surface flatness of a coating formed by the existing alumina and the thermal shrinkage optimization of a diaphragm are difficult to realize at the same time is solved.
本发明提供一种多孔氧化铝及电池隔膜、电池、用电设备，涉及电池材料技术领域，所述多孔氧化铝为颗粒的表面和/或内部中存在若干介孔的氧化铝颗粒；且所述氧化铝颗粒为厚度不低于底面边长的长度的20%的四棱柱型晶体；累积粒径分布中的小粒径侧的50%的颗粒的累积粒径D50为0.3~2μm；且所述多孔氧化铝的休止角为36.0°~38.5°。本申请还提供基于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改善了现有氧化铝所形成的涂层的表面平整度和对隔膜的热缩性优化难以兼具的问题。
