Electrode/Electrolyte Interfacial Chemistry Modulated by Chelating Effect for High?Performance Zinc Anode

چکیده

Although Zn metal has been regarded as the most promising anode for aqueous batteries, its practical application is still restricted by side reactions and dendrite growth. Herein, an in-situ solid electrolyte interphase (SEI) film formed on interface of electrode/electrolyte during plating/stripping zinc anodes introducing trace amounts multidentate ligand sodium diethyldithiocarbamate (DDTC) additive into 1 m ZnSO4. The synergistic effect forming chelate endows Zn2+ with uniform rapid interface-diffusion kinetics against growth surface reactions. As a result, in ZnSO4 + DDTC electrolytes displays ultra-high coulombic efficiency 99.5% cycling stability (more than 2000 h), especially at high current density 600 cycles 40 mA cm?2). Moreover, Zn//MnO2 full cells exhibit outstanding cyclic (with 98.6% capacity retention after 10 C). This interfacial chemistry modulated strategy provides new insight enhancing high-performance batteries.

Inhibition of invasion and angiogenesis by zinc-chelating agent disulfiram.

Cell invasion and angiogenesis are crucial processes in cancer metastasis that require extracellular matrix (ECM) degradation. Proteolytic degradation of the ECM components is a central event of invasion and angiogenesis processes. During these processes, matrix metalloproteinases (MMPs) seem to be primarily responsible for much of the ECM degradation. Disulfiram is frequently used in the treat...

Chromatographic Zinc Isotope Separation by Chelating Exchange Resin

Zinc isotope separations were studied by displacement chromatography using the chelating properties of malate, citrate and lactate exchange resin and EDTA as ligands. After each chromatographic operation, the heavier zinc isotopes were found to preferentially fractionated into the carboxylate complex solution phase. The separation coefficients (epsilon) for zinc isotope separation had the large...
