| Abstract Scope |
Reaching the border of the capable energy limit in existing battery technology has turned research attention away from the rebirth of unstable Li-metal anode chemistry in order to achieve exceptional performance. Li metal, with its high theoretical capacity, low weight, and low electrochemical potential, is considered an ideal anode. However, intrinsic challenges, such as dendrite formation, safety risks, and efficiency degradation, hinder its commercialization. Dendrites form during cycling, leading to short circuits, dead product accumulation, and mechanical stress, which lower the battery’s performance and safety.
In this presentation, I introduce surface-flattening and interface stabilizing agents employing polarizable molecular dipoles for longer and rapid operating Li metal batteries. The highly polarizable and multifunctional pyrrolidone-based molecular dipoles offer exceptional benefits, including (i) surface flattening of the Li metal anode, (ii) controlling the growth direction of crystalline Li metal, and (iii) forming durable solid electrolyte interface components. |
