Data for the publication: High performance of porous, hierarchically structured P2- Na0.6Al0.11 – xNi0.22 – yFex+yMn0.66O2 cathode materials
<p>Data sets: SEM-images, EIS, ex situ XRD, operando XRD, electrochemical cycling.</p> <p>Abstract: Sodium-ion-batteries (SIB) are a low-cost alternative to currently used lithium-ion batteries (LIB) but suffer from poor cycling stability. Spray drying provides porous, hierarchically structured particles of cathode active material (CAM) in large amounts, suitable for up-scaling. Changing the chemical composition of the Na0.6Al0.11–xNi0.22–yFex+yMn0.66O2 layered oxides under identical synthesis conditions leads to differences in particle morphology, conductivities, sodium vacancy ordering and phase transition, therefore influencing the electrochemical performance via several mechanisms. Here, a broad overview on these changes for samples with variable nickel and iron content is presented. With increasing iron content, the particle porosity is reduced and lower of initial capacity is received for most cycling windows. Substituting half of the original Ni amount with Fe still leads to high capacities and improved cycling stability. The influence of Al as electrochemical inactive element becomes visible in stabilised cycling stability as well.</p>
Porous Organic Polymers with Heterocyclic Crown Ethers for Selective Lithium-Ion Capture
<p>Abstract of the publication: Lithium is a key resource of the 21st century. Despite that, Li is traditionally mined rather than obtained from maritime brines or secondary sources such as spent energy-storage devices owing to the difficulties in Li recovery. Herein, we present a porous organic polymer capable of capturing Li ions from aqueous solutions through highly pre-organized heterocyclic crown ether-like pores in the polymer backbone. These features enable Li+ uptake capacities over 120 mg g-1 and selectivity versus highly competitive ions such as Na+, Ca2+, and Mg2+.</p> <p> </p>
A benchmark dataset for the grazing flow over porous materials
<p>Wind-tunnel data of a grazing flow over porous wall-inserts to be used as a benchmark dataset for the development and validation of numerical modeling approaches of flows over and through porous media. </p> <p>The dataset contains several profiles along the streamwise extent of the wall-insert of the mean velocity magnitude, the turbulent intensity, and the turbulent length scale. Also included are some boundary-layer parameters of these profiles. These have been derived from single-component constant temperature hot-wire measurements.</p> <p>Additionally, the spectra of the unsteady wall-pressure fluctuations at several locations on the upper and lower surfaces of the porous wall-inserts are provided. These unsteady pressure measurements have been acquired using semi-infinite waveguide-type remote-microphone probes.</p> <p>Tested are two porous media with the same <em>diamond-lattice</em> pattern structure but different permeabilities and a reference solid-walled case. All three cases are tested at three inflow velocities: 15 m/s, 20 m/s, and 25 m/s.</p> <p> </p> <p>Modification in v3: Correction of permeability values in Table 1 on page 3 of <em>AIAA_Manuscript_GrazingFlowPorousMaterials_v3.pdf</em>.</p>
