Battery anode interphase construction via carbon capture

In the April 15, 2022 issue of One Earth, Borodin, Xu, and colleagues introduce a hybrid electrolyte with a supporting salt for rechargeable Zn metal batteries, which helps construct a unique solid electrolyte interphase at the Zn anode through the reaction between additive cations and dissolved CO₂ in the electrolyte. The interphase boosts the Zn anode reversibility and cyclability remarkably by taming side reactions and dendrite formation, leading to an extended Zn anode lifespan of over 3,500 h at 0.5 mA cm⁻² and 0.5 mAh cm⁻².
