analysis, SEM, TGA-DSC and FT-IR. The formation of liquid phase at high temperature may lead to the mutual bonding between particles, which might be the main reason for the improvement of mechanical... alloy moulds (120 mm×20 mm×20 mm) and cylindrical moulds (Φ20 mm×20mm). Subsequently, they were placed in an electric blast dryer and dried at 60 °C for 48 h. After drying, they were demoulded and baked......

eV/atom远大于在石墨烯上的吸附能,同时强吸附作用是由于形成了金属碳键(Wδ+–Cδ-和Tiδ+–Cδ-).研究者也引入氮化物的复合硫正极,导电性良好的VN/与Li2S6结合能为3.75 eV,显著增强对多硫化锂的吸附作用[48];将TiN与硫正极复合,计算出TiN与S8的结合能为6.60 eV远大于石墨的结合能(0.76 eV),TiO2的结合能(1.78 eV),Ti4O7的结合能(1.28 eV),发现添加TiN有利于稳定短链多硫化物,而且协助长链多硫化物碎化为短链多硫化物,有利于放电过程中第二电压平台的出现[49].二维层状材料中的金属氧化物,硫化物,碳化物,氮化物均表现出对多硫化锂的强吸附作用. 1.2.2 三维材料 体相的三维(3D)金属化合物与多硫化锂的形成能或吸附能一般采用GGA-PBE方法计算,同时考虑vdW修正方法.计算TiO2与Ti4O7与多硫化锂相互作......
