Vapor phosphorus-coated cobalt vanadate as a high-performance anode for a lithium-ion battery

P-doping boosting electronic properties and ionic kinetics of MnV2O6 for high-performance lithium-ion batteries

“…8,9 Among them, vanadium oxides have attracted extensive interest as potential battery materials because of the multiple valence states of vanadium (V 5+ , V 4+ , V 3+ , and V 2+ ) and the rich structural chemistry, which enable versatile redox-dependent properties. 10,11 Thus, vanadium oxides can deliver remarkable theoretical capacities, which are much higher than that of the commercialized graphite anode (372 mA h g −1 ). 1,[12][13][14] However, their viability in practi-cal batteries is hampered by their limitations of poor conductivity, inferior ion kinetics, and severe volume changes upon cycling.…”

“…[27][28][29][30] Nevertheless, similar to other transition metal oxides, manganese vanadate suffers from some disadvantages such as poor conductivity for electron transfer and ion diffusion, and severe volume changes during the charging and discharging process, leading to crushing of the electrode material and thus a suboptimal rate performance and cycling stability. To address these issues, many strategies have been used to overcome these drawbacks, such as nanohybrids, 6,10,12,31 surface-coating, 5,11,32 interfacial engineering, 33 and element-doping. 34 Thereinto, the doping strategy is an effective method to improve the electrical conductivity of transition metal oxides, and can introduce oxygen vacancies, cations, and anions to modulate the energy band structure, thus improving their electrical conductivity.…”
