a high-tech 3d scientific illustration of electrochemically switched ion exchange (esix). two rectangular electrochemical cells side by side. left cell (uptake): an electric field is applied, a layered electrode material (golden-yellow layers) is capturing blue spherical anions (representing seo3 2-) from a light blue aqueous solution. electrons (e-) are flowing out of the electrode. right cell (release): reverse electric field, electrons flowing in, the blue anions are being released from the electrode back into the solution. in the middle, a glowing blue circular arrow with the text "esix". clean background, scientific, highly detailed, 8k resolution, unreal engine 5 render, ui/ux style diagram.
