Title: Electrolyte formulations for electrochemical cells containing a silicon electrode

Patent ·
OSTI ID:1771489
; ; ;

Additives to electrolytes that enable the formation of comparatively more robust SEI films on silicon anodes. The SEI films in these embodiments are seen to be more robust in part because the batteries containing these materials have higher coulombic efficiency and longer cycle life than comparable batteries without such additives. The additives preferably contain a nitrate group.
