Research Background Lithium-ion batteries (LIB) are widely used in the field…
From June 18th to 20th, The Battery Show Europe 2024 was held at the Stuttgart Exhibition Center in Germany. As Europe’s largest battery technology trade fair, it brought together over 1,100 companies from across the battery and electric vehicle supply…
1. Background The IEST Single Particle Force Testing System (SPFT) is specifically designed for lithium battery materials to evaluate the mechanical properties of individual particles, such as crush force and crush strength. This system utilizes high-precision displacement control and pressure…
The cathode material is one of the most important components of lithium ion batteries. The common cathode materials of lithium ion batteries are layered lithium cobalt oxide, olivine structure lithium iron phosphate, lithium manganese oxide of spinite structure and layered…
1. Preface In this paper, the difference of the two test methods is tested by the method of 4 point probe and 2 point probe. Lithium ion battery resistance is one of the important indicators to measure the battery performance,…
1. Background The BYD Blade Battery is an improved lithium iron phosphate battery, and there are three basic structures inside each battery, the battery cell and the battery pack. BYD Blade battery have been widely used in fields such as…
1. Abstract Sulfide-based solid electrolyte have attracted considerable attention for application in solid-state lithium batteries because of their high ionic conductivities, suitable mechanical properties, and successful operation with various active anode and cathode materials. However, sulfides react with traces of…
