Effective Solid Electrolyte Interphase Formation on Lithium Metal Anodes by Mechanochemical Modification

Figure 6. from Julia Wellmann et al. “Effective Solid Electrolyte Interphase Formation on Lithium Metal Anodes by Mechanochemical Modification”: SEM images of lithium electrodes after cycling in symmetric Li∥Li cells with liquid carbonate-based electrolytes (1 M LiPF6 in EC:EMC (3:7)) (a, f) without modification, (b, g) after mechanical modification, (c, h) after mechanochemical modification, and (d, i) after roll-pressing and immersion for 1 day and (e, j) for 7 days after (a–e) one electrodeposition step (1 mAh, 1 mA cm–2) and (f–j) after 50 cycles (1 mAh, 1 mA cm–2). AFM topography images of (k) pristine lithium, (l) mechanically modified lithium, (m) mechanochemically modified lithium, and (n) lithium immersed for 1 day and (o) for 7 days. The Atomic force microscopy (AFM) measurements were performed using a NANOSENSORS™ PointProbe® Plus PPP-ZEILR AFM probe. (Contact Mode Low Force Constant - Reflex Coating).

Lithium metal batteries are gaining increasing attention due to their potential for significantly higher theoretical energy density than conventional lithium ion batteries. * In the… Read More »Effective Solid Electrolyte Interphase Formation on Lithium Metal Anodes by Mechanochemical Modification
