1. Author Information and Article Abstract In 2020, DanielP. Abraham’s team used an electrochemical dilatometry to characterize the thickness expansion of silicon carbon com…
1. Abstract Lithium plating is a critical failure mode during fast charging—especially at low temperatures—because plated Li reduces capacity, forms electrically “dead” Li, consum…
1. Introduction Pouch cells are widely used in electric vehicles, portable electronics, and energy storage systems due to their high energy density and flexible packaging. However…
Capacity decay and loss will occur during the cycle of lithium-ion batteries, in order to improve battery capacity and performance, scholars at domestic and international have ful…
1. Introduction Accurate state-of-charge (SOC) estimation is critical for the performance and safety of lithium-ion batteries, particularly LiFePO4 (LFP) cells, which exhibit a fl…
1. Author Information and Article Abstract In 2017, the J.R.Dahn research group used the in-situ characterization method to test the volume, stress and thickness changes of the el…
1. Abstract This article demonstrates a practical, quantitative alternative: using a IEST Battery Pressure Mapping System(BPD1000) to instantly visualize and quantify surface pres…
1. Abstract A roll-to-roll process was developed to fabricate a composite lithium metal batteriesthat exhibits near-zero volume expansion during cycling. The anode uses a sandwich…
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 a…
1. Abstract This prismatic case study uses an in-situ swelling analyzer (SWE2110) to quantify swelling force and surface temperature of LiFePO4/graphite prismatic cells (40 Ah) un…
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 densit…
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/…
