Abstract |
We develop a new solution synthesis strategy for producing high ionic-conducting sulfide solid electrolyte using ethylenediamine (EDA) solvent. Here, we follow three simple steps: dissolve the precursor in ethylenediamine solvent to form the clear solution, then removing a solvent at 180 ℃ followed by heat treatment. The prepared Li5.5MPS4.5Cl1.5
electrolyte demonstrated the high ionic conductivity of 2.87 mS cm-1 at 25 ℃. Further, fabricated solid battery using optimized electrolyte exhibited a high initial discharge capacity of 175.7 mAh g-1 at 0.1 C rate. Moreover, the synthesis technique is a convenient and quick process, thus facilitating mass production of solid electrolytes. | |
