Abstract

A series of sodium phosphorothioate complexes are shown to have electrochemical properties attractive for sodium-sulfur battery applications across a wide operating temperature range. As cathode materials, they resolve a long-standing issue of cyclic liquid-solid phase transition that causes sluggish reaction kinetics and poor cycling stability in conventional, room-temperature sodium-sulfur batteries. The cathode chemistry yields 80% cyclic retention after 400 cycles at room temperature and a superior lowtemperature performance down to 260 °C. Coupled experimental characterization and density functional theory calculations revealed the complex structures and electrochemical reaction mechanisms. The desirable electrochemical properties are attributed to the ability of the complexes to prevent the formation of solid precipitates over a fairly wide range of voltage. [ABSTRACT FROM AUTHOR]

33. SnO2Quantum Dots Enabled Site-Directed Sodium Deposition for Stable Sodium Metal Batteries

Author

Xu, Ying, Matios, Edward, Luo, Jianmin, Li, Tao, Lu, Xuan, Jiang, Shuaihu, Yue, Qin, Li, Weiyang, and Kang, Yijin

Abstract

Dendrite growth has been severely impeding the implementation of sodium (Na) metal batteries, which is regarded as one of the most promising candidates for next-generation high-energy batteries. Herein, SnO2quantum dots (QDs) are homogeneously dispersed and fully covered on a 3D carbon cloth scaffold (SnO2–CC) with high affinity to molten Na, given that SnO2spontaneously initiates alloying reactions with Na and provides low nucleation barrier for Na deposition. Molten Na can be rapidly infused into the SnO2–CC scaffold as a free-standing anode material. Because of the affinity between SnO2and Na ion, SnO2QDs can effectively guide Na nucleation and attains site-directed dendrite-free Na deposition when combined with the 3D CC scaffold. This electrochemically stable anode enables almost 400 cycles at ultrahigh current density of 20 mA cm–2in Na symmetric battery and delivers superior cycling performance and reversible rate capability in Na–Na3V2(PO4)3full batteries.

Abstract

Accurate information on agricultural water needs and withdrawals at appropriate spatial and temporal scales remains a key limitation to joint water and land management decision-making. We use InVEST ecosystem service mapping to estimate water yield and water consumption as functions of land use in Fresno County, a key farming region in California's Central Valley. Our calculations show that in recent years (2010-2015), the total annual water yield for the county has varied dramatically from ~0.97 to 5.37 km3 (all ±17%; 1 MAF ≈ 1.233 km3), while total annual water consumption has changed over a smaller range, from ~3.37 to ~3.98 km3 (±20%). Almost all of the county's water consumption (~96% of total use. takes place in Fresno's croplands, with discrepancy between local annual surface water yields and crop needs met by surface water allocations from outside the county and, to a much greater extent, private groundwater irrigation. Our estimates thus bound the amount of groundwater needed to supplement consumption each year (~1.7. km3 on average). These results, combined with trends away from field crops and toward orchards and vineyards, suggest that Fresno's land and water management have become increasingly disconnected in recent years, with the harvested area being less available as an adaptive margin to hydrological stress.

Abstract

Sodium (Na) metal is a promising alternative to lithium metal as an anode material for the next‐generation energy storage systems due to its high theoretical capacity, low cost, and natural abundance. However, dendritic/mossy Na growth caused by uncontrollable plating/stripping results in serious safe concerns and rapid electrode degradation. This study presents Sn2+ pillared Ti3C2 MXene serving as a stable matrix for high‐performance dendrite‐free Na metal anode. The intercalated Sn2+ between Ti3C2 layers not only induces Na to nucleate and grow within Ti3C2 interlayers, but also endows the Ti3C2 with larger interlayer space to accommodate the deposited Na by taking advantage of the "pillar effect," contributing to uniform Na deposition. As a result, the pillar‐structured MXene‐based Na metal electrode could enable high current density (up to 10 mA cm−2) along with high areal capacity (up to 5 mAh cm−2) over long‐term cycling (up to 500 cycles). The full cell using MXene‐based Na metal anode exhibits superior electrochemical performance than that using host‐less commercial Na. It is believed that the well‐controlled MXene‐based Na anode not only extends the application scope of MXene, but also provides guidance in designing high‐performance Na metal batteries. A tin(II) ions (Sn2+) pillared titanium carbide (Ti3C2) MXene matrix serves as a highly stable host for metallic sodium (Na) anodes. The intercalated Sn2+ not only induces Na nucleation and growth within Ti3C2 interlayers, but also endows the Ti3C2 with a larger interlayer space to accommodate the deposited Na by taking advantage of the "pillar effect", effective in suppressing the favorable sites for dendrite growth.
