The team of researchers at the University of Vicuau in China has reached an important breakthrough in batteries, using X -ray computed tomography to study the interaction between electrolyte and the electrode. Opening can significantly increase battery efficiency and reduce their production cost, which is important for both mobile devices and electric vehicles.
Electrolyte moistening is a process in which the electrode is evenly distributed in the pores of the electrode, filling them. This is critical for efficient transportation of ions within the battery, and therefore for its stability, charging speed and overall productivity.
The research revealed: modern production processes, including calendering (compression of electrodes to increase density), often reduce the porosity of the material. This complicates the penetration of the electrolyte into the micropora, reducing the wettability. Other problems: partial closure of pores as a result of production pressure; The seizure of gases that do not mix with the electrolyte and interfere with the full filling of the space inside the electrode.
Manufacturers will be able to optimize the structure of electrodes, taking into account new microstructure data. The wetting will become more fuller and faster, which will provide greater battery power. Batteries will be cheaper in production, thanks to better control of the wetting process. This is especially important against the background of global demand for efficient batteries for electric vehicles, smartphones and energy storage systems.
On the basis of this study, new numerical models are developed to predict electrolyte wetting, taking into account the microstructure of materials. This will help: improve the design of batteries; increase energy efficiency; To accelerate the large -scale production of high quality nutrients.
