Cation-exchange synthesis of manganese vanadate nanosheets and its application in lithium-ion battery

Cation-Exchange Method Enables Uniform Iridium Oxide Nanospheres for Oxygen Evolution Reaction

“…To design a well-controlled iridium oxide structure, MnO 2 was used as a template because it is easily achievable on large scale; moreover, it has been frequently reported for cation exchange. − The presence of the manganese template in this synthesis played an important role in the final morphology of iridium nanoparticles, as iridium nanoparticles barely showed a specific structure in the absence of MnO 2 (Figure S1). Initially, MnO 2 nanowires were formed by the hydrothermal method, which is described in detail in the Experimental Section.…”

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

“…[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.…”
