Enhancing the performance of cylindrical Li-ion batteries via mechanical preload and optimization of impedance

Pouch and prismatic battery cells are usually mechanically preloaded for their use in electric vehicles to improve the performance and service life of battery cells. Although these positive effects are well known and studied in literature, only these cell formats continue to be m...

Detection of load orientation effects in Lithium-ion batteries via electrochemical impedance spectroscopy

This study investigates the influence of load orientation effects on the impedance response of commercial lithium-ion prismatic cells. Electrochemical impedance spectroscopy (EIS) was performed during stepwise deformation using a cylindrical impactor oriented along the cell's X-d...

Rate-dependent mechanical–electrical–thermal abuse response of fresh and aged tabless 4695 cylindrical cells under radial indentation

Electrochemical aging can alter the mechanical abuse response of large-format cylindrical cells, but its effect under dynamic loading remains insufficiently resolved. This study compares fresh and aged tabless 4695 cells at 100 % State of Charge (SoC) under dynamic radial indenta...
