Abstract

Here, we report on the electrochemical behavior of layered VOCl material as potential electrode material in rechargeable lithium-ion batteries. Orthorhombic VOCl with a space group of Pmmn was synthesized via a solid-gas reaction. During electrochemical charge and discharge a combination of intercal...
