The preparation method of the current collector assembly includes: abutting the at least one of the connection plate or the protection plate having the protrusion against the plurality of tabs; generating a high-frequency vibration between the at least one of the connection plate or the protection plate having the protrusion and the plurality of tabs; and piercing the plurality of tabs sequentially by the protrusion through the high-frequency vibration. A vibration frequency of the high-frequency vibration ranges from 15 KHz to 40 KHz.",
