1. Background In recent years, people have placed higher and higher requirements on battery life, safety, fast charging and other performance. Silicon-based anode electrode materials are new high-performance lithium-ion battery negative electrode materials due to their advantages such as high…
1. Electrode Uniformity In the manufacturing process of energy storage batteries, the uniformity of lithium battery electrode coating is an important parameter to be monitored in the early stages of cell production. It is also one of the crucial properties…
1. Preface In this paper, we adopt the in-situ electrode AB surface resistance test method independently developed by IEST to try to test the AB surface resistance of different cathode and anode electrode materials respectively, and finally clarify the measurement method…
1. Preface This article comprehensively analyzes the single and double-sided electrode conductivity and compression properties of different active materials, which can effectively distinguish the performance differences of electrodes in different coating states, it provides an effective means to more precisely…
1. Preface In this paper, four batches of gas phase silicon-carbon negative electrode wafers were produced continuously using the same deposition process and coating process, the ion conductivity of the finished wafers was evaluated by using the Multi-Channel Ion Conductivity…
1. Abstract This study primarily utilizes IEST Battery Electrode Resistance Analyzer (BER2500) to comparatively evaluate the electronic conductivity of bare aluminum foil and carbon-coated aluminum foil, as well as the LiFePO4 electrode conductivity coated on bare aluminum foil versus those…
1. Preface Slurry is an important intermediate product in the production of lithium-ion batteries, and the uniformity and stability of the slurry greatly affects the consistency and electrochemical properties of the final cell. Currently, the method of monitoring the slurry…
1. Author Information and Article Abstract In 2019, the Kentaro Kuratani team used the slurry viscosity and CT imaging characterization of different mixing methods to visually see the slurry dispersion state. Further combining with the rate performance of the button,…
1. Preface Measure the slurry resistivity can assess the dispersion and conductivity of the particles at the slurry level. At present, conductive agent studies the model of conductive network, but quantitative analysis of resistivity is rare. This paper analyzes the…
1. Background This article mainly combines the use of the same carbon skeleton and the same deposition equipment to use two different deposition processes to continuously produce four batches of vaporized silicon carbon powder materials, the conductive properties of powder…
