Therefore, it is necessary to introduce the monitoring of swell performance in the long-term cycle test of the battery.<\/p><p>Since the battery cells are combined in different numbers and in different series and parallel ways when forming battery modules, the pretightening force of modules with different designs will also be different.

Cell thickness swell test:<\/strong> Put the cell to be tested into the corresponding channel of the device, open the MISS software, set the cell number and sampling frequency parameters corresponding to each channel, and the software will automatically read the cell thickness, thickness variation, test temperature, current, voltage, capacity and other data.<\/p><h2 id=\"Experimental-process-and-data-analysis\">Experimental process and data analysis<\/h2><p>As shown in Figure 3, there are generally three modes for cell and module swell tests: (a) measurement of free swell without any constraints; (b) Cell swell measurement with constant preload applied; (c) Cell swell measurement with constant gap. A battery or modular unit can be decomposed into two equivalent stiffness components: the equivalent stiffness ka of the inner cell and the equivalent stiffness kc of the case.<\/p><p>The force analysis of the three cases under balanced conditions is shown in Figure 3. In the first case, the outer shell restricts the swell of the inner winding core, the force on the outer shell and the force on the winding core are balanced, and the external force is zero; In the second case, an external preload load ( F 0 ) is applied to the battery, causing an initial displacement of the battery case (s0 and s0,c in Fig. 3b),<\/p><p>The equivalent stiffness ks in the direction perpendicular to the electrode is increased by the binding plates on both sides of the phase. Under equilibrium conditions, the preload F0 (the same as the force Fs of the binding plate on both sides) is equal to the sum of the forces on the winding core and the battery case; In the third case, when the gap is measured constantly, the swell of the winding core and the battery case when the battery expands is also different from that under free conditions because of the fixed gap condition.<\/p><p>In short, since the module is a combination of multiple batteries, the plastic gasket between the battery case and the battery will shrink and expand during the stress process. The thickness and force tested are the combined result of the swell and contraction of lithium intercalation and extraction of electrodes and the swell and contraction of other components. In this paper, the constant pressure and constant gap test modes are used to study the correlation between the monomer and the module.<\/p><p><img decoding=\"async\" class=\"aligncenter size-full wp-image-62308\" src=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Three-modes-of-cell-and-module-unit-swell-test.jpg\" alt=\"Three modes of cell and module unit swell test\" width=\"1000\" height=\"1191\" srcset=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Three-modes-of-cell-and-module-unit-swell-test.jpg 1000w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Three-modes-of-cell-and-module-unit-swell-test-252x300.jpg 252w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Three-modes-of-cell-and-module-unit-swell-test-860x1024.jpg 860w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Three-modes-of-cell-and-module-unit-swell-test-768x915.jpg 768w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Three-modes-of-cell-and-module-unit-swell-test-600x715.jpg 600w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p><p style=\"text-align: center\"><span style=\"color: #999999\">Figure 3.

As shown in Figure 6: the solid line is the actual swell curve of the cell, and the dotted line is the fitting superposition curve (arithmetic sum).<\/p><p>From the results, both the single cell and the stacked cell show the phenomenon of charge swell and discharge contraction, which is mainly due to the structural swell and contraction of graphite and ternary materials caused by the process of lithium deintercalation. With the increase in the number of stacked cells, the overall swell thickness of the module continues to increase, and the superposition swell curve of multi-cells (blue solid line) is basically consistent with the single-cell superposition arithmetic and swell curve (blue dotted line), and there are only some differences at the end of charge and discharge.<\/p><p>This may be related to the poor consistency of each single cell, and with the increase in the number of stacked cells, the greater the difference between the measured curve and the fitted curve, this shows that the more the module with multiple cells, the higher the consistency requirements for the monomer should be.<\/p><p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-62306\" src=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Schematic-diagram-of-battery-sticking-PET-film-and-Schematic-diagram-of-battery-stacking.jpg\" alt=\"Schematic diagram of battery sticking PET film and Schematic diagram of battery stacking\" width=\"1000\" height=\"417\" srcset=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Schematic-diagram-of-battery-sticking-PET-film-and-Schematic-diagram-of-battery-stacking.jpg 1000w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Schematic-diagram-of-battery-sticking-PET-film-and-Schematic-diagram-of-battery-stacking-300x125.jpg 300w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Schematic-diagram-of-battery-sticking-PET-film-and-Schematic-diagram-of-battery-stacking-768x320.jpg 768w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Schematic-diagram-of-battery-sticking-PET-film-and-Schematic-diagram-of-battery-stacking-600x250.jpg 600w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p><p style=\"text-align: center\"><span style=\"color: #999999\">Figure 4.

From the results, as the number of stacked batteries in the module increases, the total swell force of the module continues to increase.<\/p><p>However, the absolute value of the swell force of the module cell has no multiple relationship with the swell force of the single cell, and is usually smaller than the sum of the swell forces of multiple single cells. and the more the number of stacked cells, the greater the difference in absolute value, which may be the boundary condition for controlling the constant gap, It will make the state of the single battery cell in the module different from that of a single battery cell when charging and discharging, which will affect the electrochemical performance. The reason for the difference needs to be further explored.<\/p><p>The capacity of single cells before grouping and the capacity of single cells after grouping can be taken into consideration and compared and analyzed at the same time. After stacking, the pressure does not increase linearly. It may be because the superimposed pressure of the battery cells after stacking reaches a critical value and compresses the even more microscopic space between the pole pieces, which is bound to be reflected in the battery performance!<\/p><p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-62303\" src=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Variation-curve-of-swell-force-of-each-battery-cell-and-superposition.jpg\" alt=\"Variation curve of swell force of each battery cell and superposition\" width=\"1000\" height=\"645\" srcset=\"https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Variation-curve-of-swell-force-of-each-battery-cell-and-superposition.jpg 1000w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Variation-curve-of-swell-force-of-each-battery-cell-and-superposition-300x194.jpg 300w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Variation-curve-of-swell-force-of-each-battery-cell-and-superposition-768x495.jpg 768w, https:\/\/www.takomabattery.com\/wp-content\/uploads\/2023\/01\/Variation-curve-of-swell-force-of-each-battery-cell-and-superposition-600x387.jpg 600w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" \/><\/p><p style=\"text-align: center\"><span style=\"color: #999999\">Figure 7.
