论文摘要
研究了混合系统LIBH4 LICL P2S5的性能，相对于全稳态电池。研究的材料在601℃以上的加热后经历非晶化，并伴随着LI+电导率增加，对电池电解液的应用有益。在室温下，测得的离子电导率为10-3 SCM-1，非晶化后活化能为0.40（2）EV。材料的结构分析和表征表明，BH4组和PS4可能属于相同的分子结构，其中Cl离子相互作用以适应结构单位。 Thanks to its conductivity, ductility and electrochemical stability (up to 5 V, Au vs. Li+/Li), this new electrolyte is successfully tested in battery cells operated with a cathode material (layered TiS2, theo. capacity 239 mAh g-1) and Li anode resulting in 93% capacity retention (10 cycles) and notable cycling stability under the current density 12 mA g-1 (0.05C-rate) at 501c。通过Operando Synchrotron X射线衍射在传输模式下进行进一步的高级表征，可以明确理解在中等温度下操作的固态电池电极的（DE）晶石过程。
The properties of the mixed system LiBH4 LiCl P2S5 are studied with respect to all-solid-state batteries. The studied material undergoes an amorphization upon heating above 601C, accompanied with increased Li+ conductivity beneficial for battery electrolyte applications. The measured ionic conductivity is 10-3 Scm-1 at room temperature with an activation energy of 0.40(2) eV after amorphization. Structural analysis and characterization of the material suggest that BH4 groups and PS4 may belong to the same molecular structure, where Cl ions interplay to accommodate the structural unit. Thanks to its conductivity, ductility and electrochemical stability (up to 5 V, Au vs. Li+/Li), this new electrolyte is successfully tested in battery cells operated with a cathode material (layered TiS2, theo. capacity 239 mAh g-1) and Li anode resulting in 93% capacity retention (10 cycles) and notable cycling stability under the current density 12 mA g-1 (0.05C-rate) at 501C. Further advanced characterisation by means of operando synchrotron X-ray diffraction in transmission mode contributes explicitly to a better understanding of the (de)lithiation processes of solid-state battery electrodes operated at moderate temperatures.
