We examine the effects of Li intercalation into α-V2O5 nanowires using in situ transmission electron microscopy. Combining electron diffraction and electron energy loss spectroscopy, we conclude that the pristine V2O5 nanowires form a Li2O shell, which acts as a solid state electrolyte. Thus Li+ ions … Read More
“Wine-Dark Sea” in an Organic Flow Battery: Storing Negative Charge in 2,1,3-Benzothiadiazole Radicals Leads to Improved Cyclability
Scientific Achievement 2,1,3-benzothiadiazole (BzNSN) was identified as a promising anolyte molecule for non-aqueous organic redox flow batteries. A proof-of-principle 2.36 V nonaqueous organic flow battery was developed by coupling BzNSN with DBMMB. Relatively stable performances over extended cycling were demonstrated under tested flow cell conditions, … Read More
