Simple Estimation of Creep Properties of Negative Electrode for Lithium-Ion Battery

The macroscopic creep properties of negative electrodes in lithium-ion batteries and their estimation methods have been investigated based on the microscopic structure electrode. Tensile tests were conducted a electrode consisting carbon powder polyvinylidene fluoride (PVDF) binder. stress-strain curve, time history tensile strain, rupture measured these estimated using simple model proposed this study. approximates alignment particles as body-centered cubic (bcc) or face-centered (fcc). external load was supported by PVDF binder located between particles. test results showed that mechanical affect electrode, including properties. curve strain upper lower limits model. strength agree with limit
