Control of Ionic Conductivity by Lithium Distribution in Cubic Oxide Argyrodites Li6+xP1–xSixO5Cl
No full textArgyrodite is a key structure type for ion-transporting materials. Oxide argyrodites are largely unexplored despite sulfide argyrodites being a leading family of solid-state lithium-ion conductors, in which the control of lithium distribution over a wide range of available sites strongly influences the conductivity. We present a new cubic Li-rich (>6 Li+ per formula unit) oxide argyrodite Li7SiO5Cl that crystallizes with an ordered cubic (P213) structure at room temperature, undergoing a transition at 473 K to a Li+ site disordered F4̅3m structure, consistent with the symmetry adopted by superionic sulfide argyrodites. Four different Li+ sites are occupied in Li7SiO5Cl (T5, T5a, T3, and T4), the combination of which is previously unreported for Li-containing argyrodites. The disordered F4̅3m structure is stabilized to room temperature via substitution of Si4+ with P5+ in Li6+xP1–xSixO5Cl (0.3 < x < 0.85) solid solution. The resulting delocalization of Li+ sites leads to a maximum ionic conductivity of 1.82(1) × 10–6 S cm–1 at x = 0.75, which is 3 orders of magnitude higher than the conductivities reported previously for oxide argyrodites. The variation of ionic conductivity with composition in Li6+xP1–xSixO5Cl is directly connected to structural changes occurring within the Li+ sublattice. These materials present superior atmospheric stability over analogous sulfide argyrodites and are stable against Li metal. The ability to control the ionic conductivity through structure and composition emphasizes the advances that can be made with further research in the open field of oxide argyrodites

Fluorine-Rich Oxyfluoride Spinel-Like Li1.25Ni0.625Mn1.125O3F Utilizing Redox-Active Ni and Mn for High Capacity and Improved Cyclability
No full textExtending the accessible capacity and cyclability is of central interest for cathode materials for Li-ion batteries. Here, we report the successful synthesis of a new spinel-like Li1.25Ni0.625Mn1.125O3F (Fd3 ̅m) oxyfluoride with significant cation disorder characterised by combined refinement of X-ray and neutron diffraction data. Li1.25Ni0.625Mn1.125O3F utilizes redox reactions of both Ni and Mn, accessing capacities of 225 (i.e., 1.46 Li+ capacity) and 285 mAh g-1 (i.e., 1.85 Li+ capacity) at 25 °C and 40 °C, respectively, through intercalation of additional Li+ into the lattice. Moreover, compared to lithium transition metal disordered rocksalt or spinel-like oxyfluorides previously reported, Li1.25Ni0.625Mn1.125O3F shows significantly improved cycling stability. Ex situ compositional, structural and spectroscopic analysis of samples at different states of charge/discharge confirm a single-phase intercalation reaction and high structural integrity over cycling
Data for: Fitness costs of female competition linked to resource defence and relatedness of competitors
No full textFemale reproductive success is often limited by access to resources and this can lead to social competition both within and between kin groups. Theory predicts that both resource availability and relatedness should influence the fitness consequences of social competition. However, testing key predictions requires differentiating the effects of these two factors. Here we achieve this experimentally by manipulating the social environment of house mice, a facultative communal breeding species with known kin discrimination ability. Our results support the hypothesis that resource defence can be costly for females, potentially trading off against maternal investment. When competition for nest sites was more intense, subjects: 1) were more active during resting phases, 2) responded more strongly to simulated territory intrusions via competitive signalling, and 3) produced smaller weaned offspring. However, we found no evidence that the propensity for kin to cooperate was influenced by relatedness of rivals. Communal breeding between sisters occurred independently of the relatedness of competitors, and costs of competition with non-kin were not mitigated by greater inclusive fitness benefits. Rather, communally breeding sisters weaned fewer offspring when competing with unrelated females, indicating that competition with non-kin is more costly overall. Our findings thus demonstrate that social competition has fitness costs and that associating with kin is beneficial to avoid negative fitness consequences of competing with non-kin, in addition to more widely recognised kin-selected benefits

Statistical Proxy Potentials
No full textThe Inorganic Crystal Structure Database (ICSD) contains the experimentally reported crystal structures for over 200,000 materials. We used these structures to collect the statistical data for the observed interatomic distances. Partial radial distribution functions were compiled for the 3,388 atomic pairs reported in ICSD to co-exist in a material. These data were then used to extract the effective interatomic interactions for each pair of elements
