"stabilize lithium or sodium deposits, helping keep their metallic structure intact. The discovery prevents potential battery degradation and short circuiting, and paves the way for higher energy-density metal-anode batteries... multivalent cations, such as calcium ions, that altered and strengthened the solvation structure of lithium or sodium ions in the electrolyte... modified structure moderates the reduction of lithium or sodium ions on the electrode surface and enables a stable diffusion and electric field"
