These batteries offer improved energy efficiency and safety, but a major challenge has been the formation of an interphase layer at the junction of the solid electrolyte and cathode. This ultra ...

However, for ideal battery function, the solid electrolyte interphase (SEI) plays a crucial role. Materials scientists have now studied nucleation and growth of this layer in atomic detail.

Notably, the viscous liquid layer appears before and therefore influences the formation of the solid electrolyte interphase. SEI is a crucial component of lithium-ion batteries. It is a thin film ...

As researchers at Karlsruhe Institute of Technology (KIT) found out via simulations, this solid electrolyte interphase develops not directly at the electrode but aggregates in the solution.

The fundamental properties of Lithium (Li) metal make it an attractive anode material, but one factor limiting its use is the formation and later instability of a solid electrolyte interphase (SEI).

This solid electrolyte interphase has an impact on the safety and efficiency of lithium batteries. The surface protective film prevents direct contact between the electrolyte and lithium metal ...

This discussion will focus on evolving understanding of the Solid Electrolyte Interphase (SEI) on reactive lithium metal anodes and beyond. Commercialised for the first time thirty years ago, Li-ion ...

Rechargeable aqueous zinc-iodine batteries get a lot of attention because they are safe, do not cost much, and have a high theoretical capacity. Zinc has a high theoretical capacity (820 mAh g-1 ...
