description The invention relates to a low resistance separator design in a battery cell. The present disclosure describes a battery assembly having at least one ceramic layer that includes ceramic particles and a binder. The ceramic particles may include [alpha]-alumina or [gamma]-alumina. The ceramic layer may be characterized by a porosity of greater than or about 40 vol%. In further embodiments, the one or more ceramic layers may have a weight ratio of ceramic particles to binder of greater than or about 90: 10. The battery assembly may be a battery separator characterized by a MacMullin number of less than or about 40 and a thermal shrinkage of less than or about 1 vol% after 1 hour at 140 DEG C. 本发明题为"电池单元中的低电阻分隔体设计"。本公开描述了一种电池组件，该电池组件具有至少一个陶瓷层，该陶瓷层包括陶瓷颗粒和粘结剂。这些陶瓷颗粒可包括α-氧化铝或γ-氧化铝。该陶瓷层的特征可在于大于或约为40体积％的孔隙度。在另外的实施方案中，该一个或多个陶瓷层可具有大于或约为90:10的陶瓷颗粒与粘结剂的重量比。该电池组件可以是电池分隔体，其特征在于小于或约为40的MacMullin数和在140℃下1小时之后小于或约为1体积％的热收缩率。
