This paper tests the powder compaction density and conductivity of graphite and LFP materials, and analyzes the differences between the two test methods. Measurement methods of compaction density and resistivity of lithium electric materials, detailed test methods are described in…
1. Background The rapidly evolving energy storage sector urgently demands advanced cathode materials to develop lithium-ion batteries with higher energy densities. Li-rich Mn-based cathode materials (LRM) exhibit exceptional specific capacities through additional anionic redox reactions. However, oxygen evolution induced by…
1. Introduction With the rapid development of the lithium-ion battery industry, silicon-based anode materials have gained attention due to their high theoretical specific capacity. Silicon-based slurry typically use deionized water as a solvent, with techniques like surface modification and elemental…
1. Background Conductive agent for lithium-ion battery ratio performance has played a key role, there are a lot of related studies show that it can improve the electronic transmission path, speed up the charge transmission, improve battery performance, but conductive…
1. Preface Sodium and lithium belong to the same group of elements, and their chemical properties are similar, but compared with lithium, sodium has obvious advantages in resource reserves and cost. At the same time, sodium-ion batteries have the characteristics…
1. Preface With the development of the new energy industry, lithium-ion batteries have gradually become a widely used power storage equipment. Among them, lithium iron phosphate battery is widely favored by the market because of its good safety performance, long…
IEST introduce a variety of special characterization instruments for the lithium battery industry (powder resistance meter, slurry resistance meter, electrode resistance meter, cell in-situ swelling and gas production test system, model coin swelling test system, etc.) have been widely used…
