The utility model discloses a pre-lithiation accelerating device, which comprises a rotating piece, a pre-lithiation accelerating device and a pre-lithiation accelerating device, wherein the rotating piece is used for fixing a pre-lithiation battery cell and driving the pre-lithiation battery cell to rotate; the driving part is used for driving the rotating part to rotate; and the conductive part is electrically connected with the pre-lithium battery cell. Therefore, pre-lithiation can be accelerated and the pre-lithiation effect can be improved in a rotating manner, so that lithium on a lithium belt of the pre-lithiation battery cell in the infiltration process can achieve a better consumption effect, more active lithium still exists after the SEI film is formed in the formation stage, and the lithium ion supplement rate is improved. 本实用新型公开了一种加速预锂的装置，包括：转动件，用于固定预锂电芯、并带动所述预锂电芯转动；驱动件，用于驱动所述转动件转动；导电件，与所述预锂电芯电连接。如此，通过转动的方式能够加速预锂化，提升预锂效果，使得预锂电芯在浸润过程中锂带上锂达到更好的消耗效果，从而化成阶段形成SEI膜的过程后，仍有较多的活性锂存在，提高了锂离子补充率。
