Abstract: The present disclosure relates to a battery unit and a battery module, the battery unit includes an electrode assembly, including a main body portion and a tab; two electrode terminals; and two current collecting members respectively connecting the tabs on both sides of the main body portion with the respective electrode terminals; the current collecting member includes a guiding plate and a supporting plate, the guiding plate is located on one side of the main body portion along the length direction, a reinforcement portion is arranged on the guiding plate and is configured to reduce the deformation of the guiding plate towards the main body portion; and the supporting plate is connected to an end of the guiding plate along the width direction, the tab is bent relative to the length direction and connected to the supporting plate. The battery unit can reduce the bending deformation of the guiding plate.

Abstract: A microscope having three-dimensional imaging capability and a three-dimensional microscopic imaging method are provided, the microscope including: at least one excitation device configured to generate a detectable contrast in a detection target region of a sample which is to be detected, in an excitation principal axis direction; at least one detection device, configured to detect the contrast as generated from the detection target region of the sample in a detection principal axis; and at least one movement mechanism, configured to generate a relative movement of the sample relative to the excitation device and the detection device; the relative movement is in a direction neither parallel to nor perpendicular to the excitation principal axis direction or the detection principal axis direction.
