Battery pole piece tortuosity calculation method, device and equipment and storage medium

The invention provides a battery pole piece tortuosity calculation method and device, equipment and a storage medium. The method comprises the steps that the compaction density of a battery pole piece is obtained; and obtaining the tortuosity of the battery pole piece corresponding to the compaction density according to the compaction density. As the tortuosity of the battery pole piece is directly calculated according to the compaction density of the battery, and the compaction density of the battery is relatively simpler to obtain, for example, the tortuosity of the battery pole piece under the compaction density is quickly obtained by directly obtaining the specification parameters of the battery or measuring the compaction density through a mature and quick detection method; finally, the related physical properties of the battery pole piece can be evaluated according to the obtained tortuosity. 本发明提供一种电池极片迂曲度的计算方法、装置、设备及存储介质，其包括：获取电池极片的压实密度；根据所述压实密度，得到所述压实密度对应的电池极片的迂曲度。由于电池极片的迂曲度直接根据电池的压实密度计算得到，同时，电池的压实密度
