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...
