Magnetic test battery device and in-situ magnetic detection system

The embodiment of the invention discloses a magnetic test battery device and an in-situ magnetic detection system. The device comprises an in-situ magnetic test battery adaptive to a variable-frequency alternating-current magnetic susceptibility tester. The magnetic test battery comprises positive and negative electrodes, a diaphragm, positive and negative electrode leads and a lead fixing device, one end of each electrode lead is connected with an electrode, and the other end is connected with an electrochemical workstation. The magnetic test battery can accurately eliminate magnetic noise and improve the test precision. The magnetic test battery can form a closed accommodating cavity to prevent the electrodes and the electrolyte from being oxidized, and various magnetic signal changes in the electrochemical reaction process of the battery can be detected in situ by matching with a variable-frequency alternating-current magnetic susceptibility tester. 本申请实施例公开了一种磁学测试电池装置及原位磁性检测系统，所述装置包括适配变频交流磁化率测定仪的原位磁性测试电池。
