In this paper, an in-situ swelling analyzer (SWE) is used to test the swelling thickness/temperature/internal resistance of three different cathode material systems (LCO/Graphite, NCM/Graphite, LFP/Graphite) under overcharge conditions, and compare…
1. Author Information and Article Abstract Amartya Mukhopadhyay of Brown University of Engineering and Technology, USA, 2012, employs an optical stress sensing device for real-time (in-situ) measurement of stresses in…
When the cell undergoes de-embedded lithium phase transition during the charging and discharging process, it will cause thickness swelling and volume swelling. This article uses the same test process to…
1. Author Information and Article Abstract In 2020, Central South University and CATL jointly studied the cyclic swelling force changes of the ternary system power battery under different design and…
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, the cathode material is…
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 swelling thickness…
LiFePO4 cells are often used as power trams or energy storage devices with high power or high security requirements because of their high security and stability. As the capacity of…
1. Author Information and Article Abstract In 2017, the Jaephil Cho team summarized several problems faced by the application of Si anode in the high-energy lithium-ion battery. In order to…
In this paper, in-situ expansion thickness tests are conducted on pouch cells prepared from two different ratios of mixed silicon carbon cell materials (specific capacities of 450 mAh/g and 800…
1. Author Information and Article Abstract In 2020, DanielP. Abraham’s team used an electrochemical dilatometry to characterize the thickness expansion of silicon carbon composite anode electrodes, quantified the difference in…
