Highly Conductive Networks Encapsulated Borohydride Electrolytes Enabling Superior High Rate Performance for All‐Solid‐State Li‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A nanoscale ZrB2/LiCl network encapsulated LiBH4 solid electrolyte was prepared by mechanically reacting LiBH4 with ZrCl4. Such a composite solid electrolyte exhibits fast ionic conduction and high critical current density. More importantly, the resultant solid electrolyte enables unprecedented cyclability of Li|LiNbO3@LiCoO2 and Li|TiS2 full cells at ...

Spacing Effects in Guided Vertical‐Axis Wind Turbine Arrays for Highway Energy Harvesting Under Multi‐Vehicle Wake Conditions

Energy Science &Engineering, EarlyView.
Three‐turbine guided Savonius arrays installed along highway corridors extract up to 697 J under multi‐vehicle wake conditions when spaced 12 rotor diameters apart—68% more than compact arrangements. Guide vanes boost output by 80–120%, and interior turbines respond most strongly to spacing, governing overall array performance. ABSTRACT Highway‐induced

The OVERGRID Interface for Computational Simulations on Overset Grids [PDF]

32nd AIAA Fluid Dynamics Conference and Exhibit, 2002
Computational simulations using overset grids typically involve multiple steps and a variety of software modules. A graphical interface called OVERGRID has been specially designed for such purposes. Data required and created by the different steps include geometry, grids, domain connectivity information and flow solver input parameters.
