Improved Capacity Retention for LiVO[subscript 2] by Cr Substitution
We present a layered Li-intercalation oxide that operates on the V[superscript 3+]/V[superscript 4+] redox couple. The stabilization effect of adding a +3 element into the layered LiVO[subscript 2] has been studied by first principles calculations. We identified Cr substitution into LiVO[subscript 2...

| description | We present a layered Li-intercalation oxide that operates on the V[superscript 3+]/V[superscript 4+] redox couple. The stabilization effect of adding a +3 element into the layered LiVO[subscript 2] has been studied by first principles calculations. We identified Cr substitution into LiVO[subscript 2] to be promising for stabilizing a layered material based on the V redox couple. Layered LiCr[subscript x]V[subscript 1-x]O2 (x = 0.1, 0.2, 0.4, 0.5) has been synthesized and tested electrochemically. The improved capacity retention confirms that the structural stability of delithiated LiVO[subscript 2] is improved by Cr doping. |
