Abstract: An electrochemical apparatus includes a housing, an electrode assembly disposed inside the housing, a first tab group, and a first adapting piece electrically connected to the first tab group and extending out from the housing. The electrode assembly is configured to be a winding structure including a first electrode plate. The first tab group includes M first tabs connected to the first electrode plate. A thickness direction of the electrode assembly is defined as a first direction. In the first direction, the electrode assembly includes N layers of the first electrode plate, N being greater than M. The M first tabs are each connected to the first electrode plate. A plane passing through a winding center axis of the electrode assembly and perpendicular to the first direction is defined as a winding center plane. The M first tabs are disposed on two sides of the winding center plane.

Abstract: A double-tilt sample holder for TEM, comprising: it comprise the main body of sample holder body, front-end tilt stage, drive rod, linkage, tilt axis, rotation axis, fixed axis of drive rod and sample loading stage. The axis hole is arranged at the front-end tilt stage, which is connected to the main body of the sample holder body by the tilt axis. The linkage, the boss slot and the drive rod slot are connected by the rotation axis. Two through movement guide grooves are designed symmetrically at both sides of the front-end of sample holder body, and the drive rod is fixed by the fixed axis of the drive rod, which restricts the drive rod to move reciprocally in a straight line driven by the linear stepping motor at the back-end of the main body of the holder body, further leading the tilt stage to rotate around the tilt axis. The tilt angle of the sample loading stage can be precisely controlled by the high precision linear stepping motor in the apparatus.

Abstract: A double-tilt in-situ mechanical sample holder for TEM based on piezoelectric ceramic drive belongs to the field of material microstructure-mechanical properties in-situ characterization, and it comprise two parts of sample holder shaft body and piezoelectric ceramic drive system. The sample holder shaft body comprise tilt stage, sample holder, linear stepping motor, drive rod, drive linkage. The piezoelectric ceramic drive system comprise piezoelectric ceramic loading stage, piezoelectric ceramic, connecting base and the sample loading stage realizing stretch or compression function. The double-axis tilt of the samples in X and Y axis directions is realized by the reciprocating motion back and forth of the drive rod driven by the linear stepping motor. The stretch or compression of the samples is realized by applying voltage on the piezoelectric ceramic to generate displacement and push the sample loading stage by the connecting base.
