1. Introduction To enhance the energy density of lithium-ion batteries, advancements in both materials and manufacturing processes are essential. Silicon offers a theoretical spec…
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…
Abstract Pouch cell swelling during electrochemical cycling is non-uniform: expansion force peaks in the center of the cell and is substantially weaker at the heat-sealed edges an…
Abstract Capacity decay and loss occur during lithium-ion battery cycling, and researchers worldwide have extensively studied its underlying mechanisms. Known contributing factors…
Abstract Accurate LiFePO4 SOC tracking is severely hindered across a broad operating window because the LFP battery voltage curve flat SOC estimation threshold exhibits a minute 0…
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…
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) under…
Abstract Silicon anodes undergo approximately ~300% volume expansion during lithiation — a fundamental challenge that silicon-carbon (Si-C) composite designs partially mitigate bu…
