New chemistries are being developed to increase the capacity and power of rechargeable batteries. However, the risk of safety issues increases when high-energy batteries using highly active materials encounter harsh operating conditions. Here we report on the synthesis of a unique ionogel electrolyte for abuse-tolerant lithium batteries. A hierarchically architected silica/polymer scaffold is designed and fabricated through a facile soft chemistry route, which is competent to confine ionic liquids with superior uptake ability (92.4 wt%). The monolithic ionogel exhibits high conductivity and thermal/mechanical stability, featuring high-temperature elastic modulus and dendrite-free lithium cycling. The Li/LiFePO_(4) pouch cells achieve outstanding cyclability at different temperatures up to 150 ℃, and can sustain cutting, crumpling, and even coupled thermal–mechanical abuses. Moreover, the solid-state lithium batteries with Lini_(0.60)Co_(0.20)Mn_(0.20)O_(2), Lini_(0.80)Co_(0.15)Al_(0.05)O_(2), and Li_(1.2)Mn_(0.54)ni_(0.13)Co_(0.13)O_(2) cathodes demonstrate excellent cycle performances at 60 ℃. These results indicate that the resilient and high-conductivity ionogel electrolyte is promising to realize high-performance lithium batteries with high energy density and safety.

A lot of Fe-ni metallic grgins in the inclusions from the Allende and Leoville chondrites were studied on the concentration patterns of some refractory siderophile elements, Os, Ir, Ru, Re, W, Mo and Pt, using neutron activation analysis. Our experimental results show that the grains studied in this work can be roughly classified into two types: equilibrium and non-equilibrium grains. This probably reflects their distinction in the fractionation and condensation processes of the solar system. Or the so-called non-equilibrium grains might be the relics from the supernovae *** experiments were carried out on microgram level.

探索未来主要气候情景下参考作物蒸散量（reference evapotranspiration,ET0）的时空分布可为农业水资源科学配置,科学应对气候变化对农业生产的影响提供基础数据支撑。该文利用黄淮海及周围88个站点1961-2010年逐日气象数据,Penman-Monteith公式估算的ET0为因变量,采用非线性回归分析方法对Hargreaves公式进行参数属地化订正,基于1961-2005年温度日序列,利用统计降尺度模型（statistical downscaling model,SDSM）以及大气环流模型（general circulation models,GCMs）中加拿大地球系统模式（the second generation of Canadian Earth System Model,Can ESM2）得到代表性浓度（representative concentration pathways,RCPs）4.5和8.5两种排放情景下2010-2100年温度日序列,通过率定的Hargreaves公式预测黄淮海地区ET0,并采用普通克里格（ordinary Kriging）方法进行空间化处理。结果表明：率定后的Hargreaves公式与Penman-Monteith公式的相关指数波动范围为0.65-0.85,平均值为0.80,SDSM模拟的最低温度、最高温度率定期和验证期的确定性系数都在0.95以上;未来两种气候情景下,黄淮海地区ET0整体上均呈增加趋势;RCP4.5情景下ET0从河北与山东、河南交界处形成的＂勺＂状向周围逐渐减小,在河北唐山与乐亭、江苏东台、河南驻马店附近达到最小值;RCP8.5情景下黄淮海地区2020 s（2011-2040年）、2050 s（2041-2070年）ET0的空间分布和RCP4.5非常相似,但2080 s（2071-2100年）ET0的空间分布差异较大,最高值主要分布在山东惠民县附近、河南新乡附近、安徽蚌阜和江苏盱眙附近。如不采取科学的应对措施,未来ET0的增加,可能会进一步加剧该区水资源短缺程度,该研究可为黄淮海地区水资源的优化管理和灌溉制度制定提供科学参考。
