  "textContent": "An electrolyte impregnation device of a secondary battery according to an embodiment of the present disclosure includes: a transfer part configured to move the secondary battery in a first direction; and a magnetic field application part for applying a magnetic field in a second direction to the secondary battery moved by the transfer part. A magnetic field is applied to an electrolyte flowing in a first direction, causing a magnetohydrodynamic convection flow in the electrolyte, especially a small magnetohydrodynamic convection flow near an electrode, such that, under the synergistic action of such flow force and the buoyancy force received by the bubbles, the bubbles on the surface of the electrode are moved to a gas pocket portion of the secondary battery, thereby removing the bubbles in the electrode assembly, thereby improving the impregnation performance of the electrolyte.",
