In this paper, we present a fast and green method to prepare Li0.44MnO2 nanorods by Li/Na ion exchange of Na0.44MnO2 templates. XRD and SEM confirm that the products still maintain the crystal and geometric structure of Na0.44MnO2 temples. Electrochemical tests show the capacity of Li0.44MnO2 nanorods is up to 218 mAh · g-1 at the current density of 0.1 A · g-1. Especially, the capacity of electrode is still located at 90 mAh · g-1 at the current density of 5.0 A· g-1 after cycling for 100 times. So Li0.44MnO2 nanorods have a potential application in the next generation of advanced batteries.

Agglomerated ZnMn2O4 nanoparticles with average particle sizes of 90–130 nm are synthesized by a facile chemical co-precipitation method. It is found that the consumption of precipitant ammonia has an important impact on the morphology and lithium storage property of the prepared ZnMn2O4 nanomaterials. With increasing ammonia consumption (molar ratios of Zn2+ to the precipitant ammonia of 1:10, 1:15, 1:20 and 1:25, respectively), the particle size of the prepared ZnMn2O4 nanomaterials becomes smaller, the porous morphology formed by the primary nanoparticles agglomeration becomes more obvious, and the lithium storage performance is improved. When Zn2+/ammonia mole ratio is 1:25, the prepared ZnMn2O4 material presents a reversible capacity of 780 mAh g−1 after 200 cycles at a current density of 0.5 A g−1. At a very high current density of 5 A g−1, the sample still retains a reversible capacity of 250 mAh g−1. This superior lithium storage performance of the sample is associated with its porous structure, which benefits the penetration of the electrolyte and enhances the electrochemical reaction activity of the active materials in the electrode. These results suggest that agglomerated ZnMn2O4 nanoparticles prepared by chemical coprecipitation method have potential as anode electroactive materials for next-generation lithium-ion batteries.

Exchange Membrane

Electrodialysis (ED) desalination performance of different conventional and laboratory-scale ion exchange membranes (IEMs) has been evaluated by many researchers, but most of these studies used their own sets of experimental parameters such as feed solution compositions and concentrations, superficial velocities of the process streams (diluate, concentrate, and electrode rinse), applied electrical voltages, and types of IEMs. Thus, direct comparison of ED desalination performance of different IEMs is virtually impossible. While the use of different conventional IEMs in ED has been reported, the use of bioinspired ion exchange membrane has not been reported yet. The goal of this study was to evaluate the ED desalination performance differences between novel laboratory‑scale bioinspired IEM and conventional IEMs by determining (i) limiting current density, (ii) current density, (iii) current efficiency, (iv) salinity reduction in diluate stream, (v) normalized specific energy consumption, and (vi) water flux by osmosis as a function of (a) initial concentration of NaCl feed solution (diluate and concentrate streams), (b) superficial velocity of feed solution, and (c) applied stack voltage per cell-pair of membranes. A laboratory‑scale single stage batch-recycle electrodialysis experimental apparatus was assembled with five cell‑pairs of IEMs with an active cross-sectional area of 7.84 cm2. In this study, seven combinations of IEMs (commercial and laboratory-made) were compared: (i) Neosepta AMX/CMX, (ii) PCA PCSA/PCSK, (iii) Fujifilm Type 1 AEM/CEM, (iv) SUEZ AR204SZRA/CR67HMR, (v) Ralex AMH-PES/CMH-PES, (vi) Neosepta AMX/Bare Polycarbonate membrane (Polycarb), and (vii) Neosepta AMX/Sandia novel bioinspired cation exchange membrane (SandiaCEM). ED desalination performance with the Sandia novel bioinspired cation exchange membrane (SandiaCEM) was found to be competitive with commercial Neosepta CMX cation exchange membrane.
