Cover Feature: In Silico Studies Show that –OBO Units Bound to Stable Boron Cages in (Y = C/Si) Anions Provide a Desirable Borate-Rich Solid Electrolyte Interface in Ca-Ion Batteries (ChemSusChem 17/2025)

The Cover Feature shows a calcium-ion battery standing at the center of a cosmos-inspired backdrop, symbolizing promise and power. $$ glides in from the left and accepts electrons from the calcium anode surface. This interaction triggers the transformation of –OBO groups into Ca²⁺-permeable borate species as part of the solid electrolyte interface on the right. Overall, this artwork captures the essence of molecular alchemy for predicting promising electrolytes for calcium ion battery. More information can be found in the Research Article by A. Sharma and P. Gupta (DOI: 10.1002/cssc.202500154).
