Zn3V2O8 nanoplatelets were successfully synthesized using a hydrothermal method. Formation of the Zn3V2O8 nanoplatelets was explained through splitting, exfoliation and self-aggregation mechanisms. FESEM revealed nanoplatelet morphology with thickness of 27.9 nm. HRTEM imaging confirmed the crystalline nature of the Zn3V2O8 nanoplatelets, and the SAED pattern clearly indicated the prepared sample to be Zn3V2O8. The prepared Zn3V2O8 nanoplatelets were further studied for their potential application in Li-ion batteries and supercapacitors. The discharge capacity of the second cycle was 558 mA h g -1 at 100 mA g -1 . The Zn3V2O8 nanoplatelets exhibited a maximum specific capacitance of 302 F g -1 at a scan rate of 5 mV s -1 . Furthermore, the Zn3V2O8 electrode retained about 98 % of its initial specific capacitance after 2000 cycles. The described Zn3V2O8 nanoplatelets were found to be a highly suitable electrode material for energy storage applications.

“…A material design approach to creating intimate conductive networks is to use electrochemically induced reduction–displacement reactions based on bimetallic materials where one active material serves as the reversible (de)lithiation host and a second material, often a coinage metal ion, is reduced to form a conductive network. The reduction–displacement reaction is a potentially advantageous approach that has been observed in several Li-based battery systems where the reaction is characterized by the in situ formation of conductive metallic networks during initial reduction. − The unique aspect of the conductive network that forms is that every particle can be effectively connected within the electrode matrix. Functionally, this phenomenon can lead to dramatically higher levels of electrical conductivity which can improve battery rate capability and power. ,,, Reduction displacement reactions have been seen in silver vanadates such as AgVO 3 , Ag 1/3 V 2 O 5 , Ag 1.2 V 3 O 8 , and Ag 2 V 4 O 11 as well as silver iron vanadates such as Ag 3 Fe(VO 4 ) 2 and AgFeV 2 O 7 , where the displaced ion is silver(I). ,− ,, Silver(I) ion reduction displacement has also been observed in Li-ion systems using delafossite structured materials such as AgFeO 2 and AgCuO 2 . , While silver reduction–displacement is the most widely studied reaction, there are numerous reports of copper reduction–displacement (Cu 3 V 2 O 7 (OH) 2 , Cu 5 (VO 4 ) 2 (OH) 4 , Cu 4 V 2.15 O 9.38 , and Cu 2.33 V 4 O 11 ) and even bismuth and antimony reduction–displacement (BiSbO 4 ). ,,,, …”

Electrochemical energy storage systems, specifically lithium and lithium-ion batteries, are ubiquitous in contemporary society with the widespread deployment of portable electronic devices. Emerging storage applications such as integration of renewable energy generation and expanded adoption of electric vehicles present an array of functional demands. Critical to battery function are electron and ion transport as they determine the energy output of the battery under application conditions and what portion of the total energy contained in the battery can be utilized. This review considers electron and ion transport processes for active materials as well as positive and negative composite electrodes. Length and time scales over many orders of magnitude are relevant ranging from atomic arrangements of materials and short times for electron conduction to large format batteries and many years of operation. Characterization over this diversity of scales demands multiple methods to obtain a complete view of the transport processes involved. In addition, we offer a perspective on strategies for enabling rational design of electrodes, the role of continuum modeling, and the fundamental science needed for continued advancement of electrochemical energy storage systems with improved energy density, power, and lifetime.

Kinetics and Mechanism of Turanite Reduction by Hydrogen

Turanite, Cu5(VO4)2(OH)4, is a naturally occurring mineral whose physical and chemical properties are of interest for magnetic data storage, battery applications, and catalysis. In this study, the reduction of nanostructured Cu5(VO4)2(OH)4 by H2 is investigated using a combination of scanning transmission electron microscopy–electron energy-loss spectroscopy, X-ray photoelectron spectroscopy, in situ diffuse reflectance infrared Fourier transform spectroscopy, in situ X-ray absorption spectroscopy, first-principles calculations, and kinetic analysis based on thermogravimetry. A two-step mechanism is proposed, in which Cu5(VO4)2(OH)4 is first reduced, following exponential growth kinetics, to form a stable intermediate consisting of a mix of Cu3VO4, Cu2O, and CuV2O5. The intermediate phase is then subsequently reduced in a 3-D diffusion-limited process to form two segregated phases consisting of Cu metal and V2O3 particles. The apparent energy barriers for these two steps, obtained from the kinetic analysis, were found to be 52.5 and 71.2 kJ mol–1 for Stages 1 and 2 of the reduction, respectively. These results highlight the importance of developing a rigorous understanding of the reduction processes involved in metal oxide catalyst preparation.
