Mechanism behind Argonne's Electrolyte Mixture (IMAGE) DOE/Argonne National Laboratory Caption Charging results in doubly or triply charged metal cations, such as Mg2+ (orange spheres), along with singly charged lithium ions (green spheres) being co-inserted from the electrolyte into the silicon (blue spheres) anode material. This process stabilizes the anode, enabling long term cycling of lithium-ion batteries.
