Molecular dynamics is a versatile and powerful method to study diffusion in solid-state ionic conductors, requiring minimal prior knowledge of equilibrium or transition states of the system's free energy surface. However, the analysis of trajectories for r ...
Water-in-salt electrolytes have enabled the development of novel high-voltage aqueous lithium-ion batteries. This study explores the reasons why analogous sodium electrolytes have struggled to reach the same level of electrochemical stability. Solution str ...
Through a combination of bulk, interface, and interphase effects, water-in-salt electrolytes, employing a high salt concentration, offer a wider electrochemical stability window than traditional dilute aqueous electrolytes. Here we explore chemical stabili ...
Establishing a link between atomistic processes and battery cell behavior is a major challenge for lithium ion batteries. Focusing on liquid electrolytes, we describe parameter-free molecular dynamics predictions of their mass and charge transport properti ...
Transition-metal compounds pose serious challenges to first-principles calculations based on density functional theory (DFT), due to the inability of most approximate exchange-correlation functionals to capture the localization of valence electrons on thei ...
Lithium-ion batteries provide the power for portable electronics and found many other interesting applications. It is desirable to design batteries with high energy density and long cycle life. Silicon is among the highest Li-storing anode materials in bat ...
Electric vehicles (EV) as an alternative to fossil fuel based cars play an important role for a more sustainable development of the transport sector. Traction batteries such as Lithium-ion Batteries (LIB) represent the vital part of this technology and cou ...
