Simulations of Anodic Nanopore Growth Using the Smoothed Boundary and Level Set Methods
A new numerical approach for simulating the growth of nanopores during the anodization (electrochemical oxidation) of aluminum was developed, allowing the multidimensional extension of a successful one-dimensional model with a series of interfacial. Simulations indicate that anions adsorbed to the alumina surface play a significant role in the growth and morphology of the nanopores. Read More

Compliant Glass–Polymer Hybrid Single Ion-Conducting Electrolytes for Lithium Batteries
We have successfully developed non-flammable hybrid single-ion-conducting electrolytes comprising inorganic sulfide glass particles covalently bonded to a perfluoropolyether polymer. These electrolytes present high transference numbers, unprecedented ionic conductivities at room temperature, excellent electrochemical stability, and limit the dissolution of lithium polysulfides.

Reversible Magnesium Intercalation into a Layered Oxyfluoride Cathode
Magnesium was reversibly intercalated at room temperature into an oxyfluoride cathode without the co-intercalation of electrolytes or protons and without the formation of unwanted side-products that commonly plague oxide cathodes. Read More

On Graded Electrode Porosity as a Design Tool for Improving the Energy Density of Batteries
This work shows that varying the porosity can only lead to marginal improvements in energy density compared to well-designed constant-porosity electrodes, and suggests that focusing on decreasing the tortuosity would be a better approach. Read More
