7Li NMR chemical shift imaging to detect microstructural growth of lithium in all-solid-state batteries

Abstract:

All-solid-state batteries potentially offer safe, high-energy-density electrochemical energy storage, yet are plagued with issues surrounding Li microstructural growth and subsequent cell death. We use 7 Li NMR chemical shift imaging and electron microscopy to track Li microstructural growth in the garnet-type solid electrolyte, Li 6.5 La 3 Zr 1.5 Ta 0.5 O 12 . Here, we follow the early stages of Li microstructural growth during galvanostatic cycling, from the formation of Li on the electrode...
