Abstract LFP compaction density testing measures how densely lithium iron phosphate (LFP) powder packs under a defined pressure — typically evaluated at 220 MPa using a three-point method…
1. Introduction Recently, the team of Academician Zhao Tianshou, Han Meisheng, and Zeng Lin from Southern University of Science and Technology (SUSTech) published a breakthrough study on sodium-ion battery cathode…
Abstract Powder resistivity and electrode resistivity are correlated but not perfectly linear across every processing stage. Using IEST PRCD3100 powder resistivity and compaction density tester (10–350 MPa) and…

Authors: Haoyu Wang (First Author), Jinyang Dong, Yuefeng Su, Lai Chen (Corresponding Authors) Affiliation: Beijing Institute of Technology Equipment Used: IEST PRCD3100 Powder Resistivity & Compaction Density Tester, SPFT-2000…
1. Preface This paper focuses on quantifying the extent of pressure damage to the material by using different pressures to flat-press silicon-based anode materials powders after calendering and…
1. Research Background In lithium-ion batteries, the anode material, as the main part of lithium ion diffusion and electron transport, determines the performance of the battery to a…
1. Preface The performance of lithium-ion batteries depends fundamentally on the quality of their electrodes. LiCoO2 (LCO) remains the dominant cathode material for 3C (Computer, Communication, and Consumer) electronic applications,…
Abstract Powder compaction density (also referred to as press density in some testing standards) is the bulk density of a battery electrode powder compact after applying a defined…
1. Preface The actual electrode process design, the active material, especially the cathode electrode material conductivity properties is relatively poor, the electronic transmission path is mainly realized through…
