We herein report the synthesis, crystal structure, and electrochemical performances of a new Li-based vanadium oxysulfate phase, Li 2 VO SO 4 2 , whose structure is built on vanadyl-containing VO 5 square-based pyramids and SO 4 groups linked by vertices to form layers.

Li 2 VO SO 4 2 presents a redox activity at 4. Density functional theory calculations are also performed to rationalize our findings in terms of redox activity and phase stability.

Together it all ends up being Oxygen is electro-negative. It has a partial negative charge. With oxygen pulling the electrons toward itself, the sulfur gets a partial positive charge.

Sulfur can have either a partial positive charge or a partial negative charge. We would need 32 valence electrons for 4 full outer shells 8x4 but only have Thus the charge is 2- for the ion.
