1. Abstract This study uses electrochemical impedance spectroscopy (EIS testing) to evaluate how external module pressure and state-of-charge (SOC) influence the impedance of LCO/graphite prismatic cells. Combining an in-situ swelling analyzer (SWE2…
1. Preface The in-situ swelling analyzer (SWE) launched by IEST has constant pressure and constant gap test modes, which can monitor the thickness evolution of the cell under constant pressure or monitor the change of pressure under a limited consta…
1. Preface In this paper, the in-situ swelling analyzer (SWE) is used to test the thickness of NCM cell(523/graphite cells): theoretical capacity 2400mAh under different constant pressure conditions (50N/500N/1000N) to compare and analyze the swelli…
1. Preface As new energy vehicles demand longer driving range and longer service life, automakers pursue higher volumetric energy density and smarter pack integration. One industrial solution is “removing modules and beams” — using the cell itself a…
1. Preface For lithium-ion batteries, particularly pouch cell designs encapsulated with lightweight aluminum-plastic film, external space is a critical constraint. The volume swelling that occurs during charging and discharging generates significant…
1. Preface With the rapid advancement of the new energy sector, lithium-ion batteries are now extensively used in electric vehicles (EVs). As a result, the safety performance of these batteries has become a major focal point. During long-term cyclin…
1. Author Information and Article Abstract Recently, Peng Tan’s group (first author Zhiyuan Zhang) at the University of Science and Technology of China (USTC) investigated the effects of external pressure on the polarization and cycling perfor…
