Summary: The synthesized supramolecular polymer, PNAGA, with bisamide groups forms multiple amide-hydrogen bonds on each chain side, serving as a binder for silicon-based anodes and improving interfacial adhesion and electrode material film adhesion strength. The stable inter- and intramolecular multiple amide-hydrogen bonds of PNAGA contribute to the integrity of the electrode structure and formation of a stable solid electrolyte interphase (SEI), leading to improved electrochemical performance compared to other binders like PAM and SA.

Summary: The growth of dendrites during electrodeposition still significantly hinders the practical application of lithium metal batteries. Lithium nitride modification is an effective strategy to suppress the growth of lithium dendrites. This review summarizes recent strategies of using lithium nitride to construct solid electrolyte interlayers to inhibit dendrite growth, including applying Li3N-based SEIs or ASEIs, constructing a nitrogenous microscopic structure, liquid electrolyte modification, and solid electrolyte modification. Efforts are made to provide a roadmap for constructing more stable SEIs and fabricating better batteries.

Summary: In this study, a poly(ether block amide) (PEBA) based polymer electrolyte with lithium bis-(trifluoromethanesulfonyl)imide (LiTFSI) as the Li salt is developed, which possesses good ion conductivity and suppresses the growth of Li dendrites. The electrolyte provides abundant amide groups to activate TFSI- anions and further enriches lithium fluoride (LiF) content in the SEI layer, resulting in improved cyclability and long-life span of the full-cell battery. Therefore, the PEBA based electrolyte shows great potential for solid-state lithium metal batteries.

Summary: LiSr2[CrN3] is an example of nitridochromates(IV) with slightly pyramidal trigonal units [CrN3](5-), which are usually difficult to obtain. Magnetic measurements, vibrational spectroscopy, and shorter Cr-N bond lengths compared to other nitridochromates confirm the presence of Cr(IV). LiSr2[CrN3] is a nonmagnetic semiconductor with highly polar N-dominated N-Cr and Cr-dominated multi-atom bonds.

Summary: The chemical and physical properties as well as the structural features of a Protic Ionic Liquid (PIL) formed by neutralization of a super-strong base with a super-strong acid have been investigated in this study. The role of hydrogen bonding (HB) in affecting the morphology of the PIL has been highlighted, and a comparison between HB features in this PIL and related PILs has been presented. Differences in HB interaction have been observed and explained based on the geometrical properties of the main conformers contributing to the experimental spectra.

Summary: Li-rich layered oxide (LRLO) materials are promising positive-electrode materials for Li-ion batteries, but the impact of antisite defects on battery functional properties is controversial. In this study, we analyzed the formation of Li/Ni antisite defects in the Co-free LRLO Li1.2Mn0.6Ni0.2O2 compound using density functional theory calculations and a thermodynamic model. Our results provide insights into the concentration of antisite defects in the trigonal lattice as a function of temperature and shed light on the native disorder in LRLO and the role of synthesis protocols in promoting antisite defect formation.

Summary: The hydrogen/deuterium sorption properties of Ni33Ti39Nb28 alloy synthesized by vacuum induction melting were investigated. The results showed that the Sieverts law is valid up to a hydrogen or deuterium to metal ratio of 0.2. The enthalpy changes for hydrogenation and deuteration were determined to be 85 +/- 5 kJ/mol and 84 +/- 4 kJ/mol, respectively. The diffusion coefficient and activation energy for both hydrogen isotopes were also obtained.

Summary: This study proposes a reliable algorithm to estimate the electrochemical stability of ionic liquids by evaluating the linear dependence between the anodic limit and HOMO level of 27 different anions. The solvation energy of the ions is found to have a significant impact on the anodic limit, and an empirical model considering this effect is proposed for the first time. This research is of great importance for the rapid discovery of suitable anions capable of sustaining high potentials.

Summary: The morphological changes and composition of the solid-electrolyte interphase layer of Si nanowires cycled in ethylene-carbonate (EC)/diethyl-carbonate (DEC) with different additives were investigated using experimental microscopic and spectroscopic techniques. Scanning electron microscopy and optical spectroscopy revealed that the presence of fluoroethylene carbonate (FEC) and vinylene carbonate (VC) additives preserved the nanowire morphology better compared to the additive-free electrolyte. Furthermore, the FEC additive mitigated amorphization of silicon and limited degradation of the LiPF6 salt.

Summary: This study investigates the impact of ionic liquid (ILs) design on the mechanical properties and ion dynamics of ILs, while considering the relationships between different mechanical and transport properties. The mechanical properties of quaternary ILs with rigid anions are studied using Dynamical Mechanical Analysis (DMA), and the results are compared with rheological and transport properties measured through viscosity, conductivity, and diffusion coefficient measurements. The temperature dependence of different variables is well described by the Vogel-Fulcher-Tammann model. The occurrence of a relaxation process in the mechanical spectra of all measured liquids is attributed to a diffusive process when the ion dynamics are not affected by fast structural reorganization of flexible anions at a local level.
