1. Preface Lithium-ion battery is an electric-heat-force coupling system, which has swelling problems in the actual use process. On the one hand, the SEI film is formed, and the air pressure…

In this paper, the in-situ swelling analyzer (SWE) is used to test the swelling force and the temperature change of the LiFePO4 prismatic cells under different initial preload (60kg/90 kg/120…

1. Preface With the continuous improvement of the endurance requirements of new energy vehicles, battery anode materials are also developing in the direction of high energy density. Although the traditional…

1. Preface In recent years, lithium-ion batteries have been widely used in consumer electronics, electric vehicles, energy storage power stations and other fields due to their high specific capacity and…

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…

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…
