Battery standing method and device

A battery standing method, comprising the following steps:

• S1:
• putting a battery subjected to electrolyte injection into an electrolyte injection capsule, and then transferring the electrolyte injection capsule and the battery in the electrolyte injection capsule to a first transfer conveying line;
• S2:
• conveying the electrolyte injection capsule and the battery in the electrolyte injection capsule to a standing unit through the first transfer conveying line;
• S3:
• transporting the electrolyte injection capsule on the first transfer conveying line and the battery in the electrolyte injection capsule into a standing cavity of the standing unit, and electrically connecting an auxiliary energizing mechanism on the standing cavity with a positive electrode probe and a negative electrode probe of the electrolyte injection capsule;
• S4:
• connecting the auxiliary energizing mechanism on the standing cavity with a power supply to supply power to a heating plate of the electrolyte injection capsule, and energizing the heating plate to heat the battery in the electrolyte injection capsule;
• S5:
• docking a positive-negative pressure circulating mechanism on the standing cavity with an air inlet of the electrolyte injection capsule and plugging an electrolyte injection port of the electrolyte injection capsule, connecting the positive-negative pressure circulating mechanism with a vacuumizing device, and vacuumizing an interior of the electrolyte injection capsule and introducing nitrogen through the positive-negative pressure circulating mechanism by the vacuumizing device alternately to vacuumize an interior of the battery in the electrolyte injection capsule and introduce nitrogen alternately;
• S6:
• disconnecting the auxiliary energizing mechanism from the power supply and disconnecting the positive-negative pressure circulating mechanism from the vacuumizing device, separating the positive-negative pressure circulating mechanism from the air inlet of the electrolyte injection capsule and the electrolyte injection port of the electrolyte injection capsule, and then transporting the electrolyte injection capsule in the standing cavity and the battery in the electrolyte injection capsule to a second transfer conveying line;
• and
• S7:
• conveying the electrolyte injection capsule and the battery in the electrolyte injection capsule to a next process through the second transfer conveying line.
