1. Article Abstract Silicon-based electrodes are promising for high-capacity lithium-ion batteries but are challenged by large mechanical changes during cycling. This study—buildi…
1. Abstract This study characterizes thickness expansion during formation of silicon-carbon composite cells with different silicon loadings (450 Si/C vs 800 Si/C) using an …
1. Abstract The expansion behavior of silicon-carbon cells is primarily attributed to the volumetric expansion of the silicon component. Excessive accumulation of irreversible exp…
Lithium-ion battery charging and discharging cycle is a complex physicochemical reaction process, and battery cycle life is affected by a variety of factors. On the one hand, it i…
1. Lithium Plating Phenomenon Lithium plating is a common anomaly in lithium-ion batteries during the use of lithium-ion batteries. The direct cause of lithium plating phenomenon …
Abstract Cell mechanical stiffness affects appearance, module integrity and abuse resistance of lithium-ion batteries. We used an in-situ swelling analyzer (IEST SWE2110) to quant…
1. Preface In this paper, we adopt the in-situ swelling analysis system(SWE Series) of IEST to monitor the pressure and thickness deformation of the battery by correlating the SOC…
1. Preface During the charge and discharge process of lithium-ion batteries, the swelling of the battery cells will occur due to the structural swelling of the positive and negati…
Abstract Accurate Expansion Analysis of lithium-ion pouch cells — tracking both thickness change and expansion force — is essential for cell design optimization and safety assuran…
During the charging and discharging process of lithium-ion batteries, as lithium ions are continuously inserted and removed, the thickness of the battery will expand and shrink to…
