Improvement of stability and solid-state battery performances of annealed 70Li2S-30P2S5 electrolytes by additives
文献摘要：
The replacement of liquid electrolyte with solid electrolyte can significantly improve the safety and power/energy density of lithium batteries.70Li2S-30P2S5 is one of the most promising solid electrolytes with high con-ductivity for solid-state batteries.In this work,the ionic conductivity and stability toward moisture and lithium metal of 70Li2S-30P2S5 were enhanced by introducing the different amounts of Li2O additives.65Li2S-30P2S5-1％Li2O delivered the highest conductivity,while 65Li2S-30P2S5-5％Li2O showed the best moisture stability and improved lithium compatibility.Solid-state batteries using 65Li2S-30P2S5-5％Li2O electrolyte and high-voltage LiNi0.6Mn0.2Co0.2O2 cathode exhibited low initial dis-charge capacity (100 mAh·g-1) and Coulombic efficiency(69％).Li3InC16 electrolytes were introduced both in the cathode mixture to replace sulfide electrolyte and in the interface layer to improve the cathode compatibility for the solid-state batteries,showing enhanced discharge capacity(175 mAh·g-1) and improved initial Coulombic efficiency(86％).Moreover,it also exhibited good performance at-20 ℃.
