Description

As a form of power battery, cylindrical cells not only have advantages such as good consistency, higher safety, high energy density, and small internal resistance compared to square shell cells. And positive and negative co-polar cylindrical cells have higher space utilization rate compared to traditional cylindrical cells with positive and negative electrodes on different sides, so that more cells can be arranged in a power battery of the same size, further improving the energy density.
[0003] After the production of positive and negative co-polar cylindrical cells, formation equipment needs to be used to perform formation operations on them, that is, charge and discharge them to activate the internal chemical substances; due to the small size of positive and negative co-polar cylindrical cells, in order to ensure production capacity, the cell trays loaded with positive and negative co-polar cylindrical cells are often arranged extremely densely. Traditional formation equipment connects the probe modules in parallel, resulting in a large number of power lines; and the formation equipment is also extremely compact due to space limitations.
