Lithium-metal anode animation (IMAGE) DOE/Pacific Northwest National Laboratory Caption The left image shows electrolyte (blue) filling a pocket within a thin lithium anode, creating an effective, wet SEI (green). The right image shows what occurs with a thicker lithium anode: The electrolyte must go deeper, depleting most of the electrolyte and resulting in an SEI that is largely dry and ineffective.
