1. Introduction The performance of modern energy storage, from electric vehicles to smart devices, hinges on lithium-ion batteries. At the heart of these batteries lies the electrode, whose…
1. Background With the rapid advancement of lithium-ion battery (LIB) technology, the performance of electrode materials has become a critical factor influencing overall battery performance. As a key…
Abstract Battery electrode flexibility is a critical performance indicator that determines an electrode’s ability to withstand the volume changes and mechanical stresses of repeated charge-discharge cycling without cracking or…
1. Article Information Title: Redox-active stabilizer-enhanced structural and thermal stability of Ni-rich cathodes via an economical blending strategy First Author: Jinzhong Liu Corresponding Authors: Jinyang Dong*, Meng Wang*,…
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…
1. Introduction Recently, BYD’s “Megawatt Flash Charging” technology has attracted significant attention in the lithium battery field. Its “5-minute charge for 800-mile range” oil-electric equivalent technology is as…
Abstract Conductive additive content in a lithium battery electrode has an optimal range rather than a “more is better” relationship: too little additive leaves electron pathways broken, while…
Abstract Separator ionic conductivity (symbol \(\sigma\), unit S/cm) quantifies how readily Li\(^+\) ions transport through a battery separator — a key determinant of cell power and rate capability.…
1. Abstract Electrolyte wetting is a critical process for lithium-ion cell performance: it controls ionic access to active material, influences rate capability and cycling, and affects initial manufacturing…
Abstract A current collector in a battery is the metallic foil—copper for the anode, aluminum for the cathode—that conducts electrons between the active material coating and the external…
1. Preface In this paper, we explore the correlation between electrolyte wettability and electrode tortuosity by testing the tortuosity and wetting rate of electrodes with different compaction densities…
Abstract Electrolyte wetting in lithium-ion batteries refers to the ability of the liquid electrolyte to fully penetrate the pores of electrode coatings and separators, forming continuous solid–liquid interfaces…
