During the charging and discharging process of lithium- ion batteries, as lithium ions are inserted and extracted in the negative electrode, the cells will expand and contract;
Ideally, the insertion and extraction of lithium ions are reversible, but in the actual cycle process, there will always be a part of lithium that cannot be extracted from the negative electrode or deposits on the surface of the anode as an insoluble by-product during the cycle, resulting in irreversible swelling of the battery cell;
Or other more serious consequences, such as the deformation of the battery cell, the fragmentation of material particles, the rupture of the SEI film, and the consumption of electrolyte. The swelling behavior of the battery has become an important indicator for evaluating the reliability of the battery. During the production process, the particle size, binder and pole piece structure of the negative electrode material must be optimized in advance;
The theoretical swelling ratio of next-generation high-energy density anode materials, such as silicon and lithium metal, is much greater than that of graphite anode materials. Therefore, accurate and effective evaluation of the swelling behavior of the battery cell can effectively guide the installation design of the battery cell module to ensure safety under the premise of improving module space utilization;
