Summary: Recent studies have shown that 2D materials, such as siloxene and germanane, can exhibit excellent performance as electrodes in alkali metal ion batteries. The improved electrochemical behavior of these materials is likely due to their limited volume change during charge and discharge, which is based on an intercalation mechanism rather than alloying. To combine the cheapness of Si and high electronic conductivity of Ge, we propose a new series of layered materials called siliganes, which are 2D Si-Ge composites. Among them, siligane_Si0.1Ge0.9 demonstrated the best electrochemical performance in Na- and K-ion batteries.

Summary: Layered oxides with the composition NaxMO2 have attracted attention for their composition diversity and promising electrochemical performances in sodium-ion batteries. This study attempts to synthesize sodium-rich P-type NaxMn2/3Ni1/3O2 and NaxMn1/2Ni1/2O2 and investigates their electrochemical behavior. The optimization of the synthesis protocol led to stabilize only P3-type single-phases. The investigation shows that the actual Na content is limited but still higher than conventionally reported for most of P3-type layered oxides.

Summary: Various ammonium vanadate compounds were successfully synthesized through ethylene glycol (EG) regulated polyol-reduction strategy and hydrothermal reaction with solvent effect. The morphology and crystalline phase of the compounds evolved from dendritic (NH4)2V6O16 to rod-like NH4V4O10 and finally to lamellar (NH4)2V4O9 with increasing amount of EG. NH4V4O10 exhibited high initial capacity and stable cycling performance, attributed to its stable open-framework layered structure, favorable (001) interplanar spacing, and peculiar rod-like morphology, which facilitated highly reversible Zn2+ storage behaviors.

It is found that the Ni/Mn order is maintained at room temperature in samples prepared at certain temperatures, and a defect structure called antiphase domain boundaries (APBs) is observed. The synthesis temperature and nickel content are shown to affect the defect density and voltage profile.

Summary: Investigation of electrochemical lithium (de)intercalation in an atomic layer deposited (ALD) TiO2 anatase thin film on a Si/Al2O3/Pt substrate was performed using Raman spectroscopy. The initial discharge capacity at C/10 rate was 63 mu Ah cm(-2) mu m(-1) (0.5 Li+ mole(-1)), which increased to 77 mu Ah cm(-2) mu m(-1) after further cycles. The ALD thin film exhibited excellent capacity retention over 100 cycles, indicating its good adherence. Raman spectra of LixTiO2 (0 <= x <= 0.5) thin film electrodes suggest the nucleation of the orthorhombic lithiated titanate (LT) Li0.5TiO2 phase at x = 0.1. The LT phase coexisted with tetragonal TiO2 in the composition range of 0.1 <= x <= 0.4, and was pure at x = 0.5. Reversible transformation from orthorhombic LT to tetragonal TiO2 was observed during charging. The high quality of the Raman spectra allowed identification of 12 modes in the 100-800 cm(-1) region for the electrochemically formed LT phase. Raman spectroscopy proved to be a powerful tool for investigating the Li insertion/extraction mechanism in TiO2 thin films.
