Summary: Ti/Fe substitution in ramsdellite LiTi2O4 has been studied, and the results showed that the substitution mechanism is more complex than predicted, involving the participation of Fe3+/Fe2+ and Ti4+/Ti3+. The LiFe0.125Ti1.875O4 material with low Ti/Fe substitution performed better than undoped LiTi2O4, and in the high voltage range, it outperformed higher Fe-substituted ramsdellites.

Summary: Low-cost Fe can be used as an alternative to high-cost d(0)-species for the formation of cation-disordered rocksalt Li-excess (DRX) materials. However, Fe-based DRX materials have several challenges, such as large voltage hysteresis, low electrochemical activity, and poor cyclability. In this study, a novel Li-Fe-Ti-Mo electrode material (LFTMO) with high capacity and reasonable stability is reported. The introduction of redox-active Mo4+/5+ into Fe-based DRX materials helps stabilize the oxygen redox reaction and suppress the Fe redox reaction, improving the performance of the electrode material.

Summary: In freshwater wetlands, the redox interfaces contribute to the growth of microaerophilic iron(II) oxidizing bacteria and the formation of flocs. Fe-rich surface-, ground- and spring water replenish wetlands on the volcanic island of Iceland. Accumulations of bright orange flocs, consisting of Fe minerals and microorganisms, are common features of Icelandic wetlands, and they are likely to be transported to coastal waters. However, little is known about the mineral and elemental composition of the flocs.

Summary: In this study, the redox activity of commercially obtained K4Fe(CN)(6)center dot xH(2)O and K3Fe(CN)(6) in solid-state supercapacitors was examined using cyclic voltammetry and X-ray absorption spectroscopy. The results showed that K4Fe(CN)(6)center dot xH(2)O was stable, while Fe(III) in K3Fe(CN)(6) was reduced to Fe(II) during electrode synthesis. Based on the XANES data, approximately 50% of the Fe in both K4Fe(CN)(6)center dot xH(2)O and the reduced form of K3Fe(CN)(6) underwent oxidation-reduction reactions during electrochemical cycling.

Summary: The study investigates the magnetic, structural, and dielectric properties of Bi5FeTi3O15 (BFTO) in the temperature range of 5K-300K. It is observed that BFTO undergoes iso-structural modifications at low temperatures (around 100K) with signatures of dielectric relaxation. Experimental methods confirm that the distribution of Fe/Ti ions in BFTO is random, and phase-pure BFTO remains non-magnetic at the lowest temperatures.

Summary: In this study, a potassium salt monohydrate melt electrolyte was prepared by mixing potassium salts, and it showed a wider potential window and improved reversibility compared to the pure components. The monohydrate melt electrolyte also reduced degradation of the electrode and crystal structures. This was attributed to the lower solubility of PTCDI and the formation of a solid electrolyte interphase consisting of FSA(-) decomposed products.

Summary: Layered manganese oxides with Cu substitution for Mn have been studied for sustainable sodium-ion battery materials. The study focused on the structural evolution and oxygen redox activation, finding that the type of substituent does not affect oxygen redox, but the nature and concentration of the substituted element(s) influence structural evolution. Cu substitution in P2-type Na0.67[Cu0.2Mn0.8O2] resulted in suppressed voltage hysteresis but could lead to lattice stress affecting cyclability.

Summary: It has been found that dual substitution of Ti-IV for Mn-IV and Zn-II for Ni-II in P2-Na-2/3[Ni1/3Mn2/3]O-2 can disturb the Na+-vacancy ordering, resulting in almost non-step voltage curves and high reversible capacity with maintained crystalline structure. Synchrotron X-ray, neutron, and electron diffraction measurements reveal that the dual-substitution uniquely promotes in-plane Ni-II-Mn-IV ordering, which differs from the disordered mixing in conventional multiple metal substitution.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
