The wettability of electrodes increases the power and energy densities of the cells of lithium-ion batteries, which is vital to improving their electrochemical performance. Numerous studies in the past have attempted to explain the effect of electrolyte and calendering on wettability. In this work, the wettability behavior of structured and unstructured LiFePO₄ electrodes was studied. Firstly, the wettability morphology of the structured electrode was analyzed, and the electrode geometry was quantified in terms of ablation top and bottom width, ablation depth, and aspect ratio. From the result of the geometry analysis, the minimum measured values of aspect ratio and ablation depth were used as structured electrodes. Laser structuring with pitch distances of 112 μm, 224 μm, and 448 μm was applied. Secondly, the wettability of the electrodes was measured mainly by total wetting time and electrolyte spreading area. This study demonstrates that the laser-based structuring of the electrode increases the electrochemically active surface area of the electrode. The electrode structured with 112 μm pitch distance exhibited the fastest wetting at a time of 13.5 s. However, the unstructured electrode exhibited full wetting at a time of 84 s.

War crimes, crimes against humanity and genocide were committed in the war in Tigray. This article focuses on the use of sexual violence as an instrument of war. It narrates the scale, nature, and intentions of the sexual violence perpetrated on Tigrayan women, girls, men and boys. It showcases the extreme cruelty, dehumanization and intent to sterilize and inflict maximum damage from stories of victims and witnesses. It compares them with the rape crimes committed in other cases and concludes the nature of the crime was genocidal.
