1. What is Cyclic Voltammetry? Cyclic Voltammetry (CV) is a fundamental electrochemical characterization technique, often termed the “diagnostic report” and “performance decoder” for electrode materials. Its principle involve…
1. Background In battery R&D and quality control, charge-discharge test equipment serves as a “diagnostic center” for cells. By precisely controlling parameters such as current, voltage, and temperature, it not only measures fundamen…
Within the battery testing field, Electrochemical Impedance Spectroscopy (EIS) is an indispensable analytical technique. Functioning like an “X-ray machine,” it enables non-destructive interrogation of a cell’s internal state, prov…
1. Article Information: Title: Efficient Electrochemical Exfoliation of Halogen-Terminated MXenes Mediated by Gaseous Molecules and Their Enhancement in Wear-Resistant Tribovoltaic Devices First Authors: Qi Fan, Minghua Chen, Longyi Li Corresponding…
1. Introduction Electrochemical Impedance Spectroscopy (EIS) is one of the most important techniques for studying electrochemical interface issues and is widely used to investigate the electrochemical behavior within lithium-ion batteries. Its princ…
1. Research Background In recent years, with the rapid expansion of the new energy vehicle market powered by lithium-ion batteries (LIBs), the number of retired LIBs is expected to increase significantly over the next 5–10 years. Therefore, lithium …
1. Background In investigative reports on energy storage station explosions or the charred remnants of new energy vehicle fires, “battery failure” is consistently identified as a core culprit. As a complex electrochemical system, lithium…
1. Preface Galvanostatic Intermittent Titration Technique (GITT) is a transient measurement technique that quantifies the diffusion capacity of lithium ions in the electrode material through the relationship of potential change with time.[1] [2] A …
Battery cell consistency is one of the difficulties that the major battery cell manufacturing companies are focusing on. In the manufacturing process of battery cells, due to fluctuations in materials, equipment and environment, there will be minor …
1. Background Introduction In new energy vehicles or energy storage stations, lithium-ion batteries are often used in modular or battery pack (Pack) configurations, where cells are connected in parallel and series. If any individual cells have perfo…
