1. Preface Mechanical properties are an increasingly important performance axis for lithium-ion cells. In electric vehicles, cells experience external loads during assembly, therm…
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 To accurately measure pressure in pouch cell tests — tracking both thickness change and expansion force — is essential for cell design optimization and safety assurance 1…
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…
1. Introduction This study utilizes in situ swelling analysis to directly compare the overcharge response of three commercial lithium-ion cell types, each featuring a different ca…
1. Article Abstract We present a clear, engineering-focused translation of Amartya Mukhopadhyay’s in-situ optical stress study on thin-film graphite electrodes (CVD C) paired with…
Abstract This study uses synchronized in-situ measurement to quantify Thickness Swelling and volume swelling of LiFePO₄ (LFP)/graphite pouch cells during charge–discharge. Because…
1. Abstract A 2020 collaborative study by Central South University and CATL investigated the cyclic swelling force evolution in NCM (Nickel Manganese Cobalt) lithium-ion power bat…
Due to its safety and stability, LFP batteries are increasingly popular in the new energy storage and electric vehicle industries. Currently commonly used LFP system batteries, th…
1. Author Information and Article Abstract In 2014, Bernhard Bitzer et al. published a method for monitoring the lithium plating of battery cells by in-situ detection of battery s…
Abstract LiFePO4 Cell swelling during charge/discharge can be characterized by two related but distinct measurements: thickness swelling (dimensional change under constant applied…
1. Abstract The pursuit of higher energy density in lithium-ion batteries has positioned silicon as a promising next-generation anode material due to its high theoretical capacity…
