This article discusses a new method for evaluating electrolyte performance in lithium-ion batteries, focusing on the correlation between electrolyte rate performance and electrode sheet tortuosity by introducing electrode sheet tortuosity and calculating the McMullin Number. Emphasizes how the microstructure of…
1. Preface Copper foil and aluminum foil are used as the current collector of lithium ion battery electrodes, which can conduct electrons and carry active materials. The chemical and electrochemical stability of the current collector will also affect the cycle,…
LiFePO4 cells are often used as power trams or energy storage devices with high power or high security requirements because of their high security and stability. As the capacity of a single cell rises, its expansion during charging and discharging…
1. Author Information and Article Abstract In 2017, the Jaephil Cho team summarized several problems faced by the application of Si anode in the high-energy lithium-ion battery. In order to improve the volume and energy density of the battery, the…
1. Preface All solid-state Battery (ASSB) are the most promising next-generation energy storage systems due to their high theoretical energy density and intrinsic safety. However, the limitation of the “solid-solid” contact between the electrodes and the solid electrolyte severely hinders…
1. Author Information and Article Abstract In 2018, the Antje Schilling team proposed a new in situ X-ray device for observing the electrolyte filling and infiltration process in the injection stage. On the one hand, it can provide reference for…
In this paper, in-situ expansion thickness tests are conducted on pouch cells prepared from two different ratios of mixed silicon carbon cell materials (specific capacities of 450 mAh/g and 800 mAh/g, respectively) to compare and analyze the differences in the…
1. Author Information and Article Abstract In 2020, DanielP. Abraham’s team used an electrochemical dilatometry to characterize the thickness expansion of silicon carbon composite anode electrodes, quantified the difference in electrode expansion when mixing different ratios of silicon-carbon, and analyzed…
The following are recent developments and innovative approaches in the field of solid-state battery, with some findings excerpted from reports by universities and research institutions. 1. Negative electrode-free all-solid-state battery, latest Nature Energy! Ying Shirley Meng’s team at the University…
1. Background Introduction In new energy vehicles or energy storage stations, lithium-ion batteries are often used in modular or battery pack (Pack) configurations, where cells are connected in parallel and series. If any individual cells have performance defects or safety…
