Description
1. Significance of Volume Swelling Testing for Cylindrical Battery
Significance: During the charge and discharge processes of lithium ion batteries, as lithium ions intercalate and deintercalate into the positive and negative electrode materials, the cell undergoes reversible expansion and contraction. Concurrently, various side reactions occur, such as particle fracture, SEI membrane rupture, cell deformation, lithium plating, gas evolution, etc., resulting in irreversible deformation.
Limitations of Existing Methods: Curently, there are several methods available to characterize the expansion of cylindrical batteries, such as vernier calipers cordinate measuring machines, presure fims, strain gauges, and imaging analysis technigues (including CT scanning, neutron imaing, X-ray, ultrasound etc.) However, these methods suer from low accuracy, inability to conduct in-situ testing, and inability to acurately and comprehensively describe the expansion behavior of cylindrical batteries.
Application Scenarios: Material evaluation, evaluation ofthe modification results of silicon anode, high-nickel ternary, lithium-rich manganese-based and other materials used in cylindrical batteries; structural evaluation, evaluation of cylindrical battery core structures of different sizes, rolled core structures. and shell rupture risk assessment; Working condition evaluation, evaluation of working conditions at different temperatures, charge/discharge rate, storage, etc.
