recuperated into a beaker. Indeed, the volume of ball-milledenergetical powders was much lower, indicating that the carbon particles might have got compacted. XRD patterns (Figure 4-24) of corresponding ball-milled powders and as received Li2S show the peaks attributed to the cubic Li2S. Slight broadening of the peaks is observed for ball-milled powders, with a more pronounced effect for energetic milling, where nano-Li2S is formed. Little traces of LiOH are also found here (probably because the sample covering with Kapton® was not sufficiently air-tight). Figure 4-24. XRD patterns of Li2S/SuperP® ball-milled powders obtained through highly energetic (in green) and planetary (in blue) ball-milling. Pure as-received Li2S is shown for comparison (in black). Traces of LiOH impurities can be also seen. Galvanostatic cycling results of the electrode prepared with planetary ball-milled Li2S/SuperP® mixture did not show any significant improvement as compared with the manually grinded as- received Li2S powder. Initial charge shows high polarization as well, while the capacity retention during prolonged cycling is also similar to what was previously demonstrated. Cycling behavior of the electrode prepared from energetically ball-milled Li2S/SuperP® powders are presented on Figure 4-25, in comparison with an electrode made in parallel from as-received Li2S powder which was manually grinded. Only initial cycle profiles are compared. Chapter 4: Li2S electrode 140PDF Image | Accumulateur Lithium Soufre
