Design Principles for Grain Boundaries in Solid‐State Lithium‐Ion Conductors

Design principles for solid-state lithium superionic conductors.

Lithium solid electrolytes can potentially address two key limitations of the organic electrolytes used in today's lithium-ion batteries, namely, their flammability and limited electrochemical stability. However, achieving a Li(+) conductivity in the solid state comparable to existing liquid electrolytes (>1 mS cm(-1)) is particularly challenging. In this work, we reveal a fundamental relations...

THE EFFECT OF STRAIN ON GRAINS AND GRAIN BOUNDARIES IN YBa2Cu3O7−δ COATED CONDUCTORS (POSTPRINT)

The role of grains and grain boundaries in producing reversible strain effects on the transport current critical current density (Jc) of YBa2Cu3O7−δ (YBCO) coated conductors that are produced with metal–organic deposition (MOD) was investigated. The strain (ε) dependence of Jc for full-width coated conductors is compared with that for samples in which the current transport was limited to a few ...

CONSIDERATION OF DESIGN FOR PRODUCTION PRINCIPLES IN SHIP HULL DESIGN

In designing for ship production, the production method should be considered and it’s possible to reduce the manufacturing cost in designing procedure. A review of background of ship design that had minimized production costs, shows the principles and problems of these methods. Modern designing methods for manufacturing, considers hydrodynamic efficiency and less manufacturing cost. Quant...

The Effects of Grain Boundaries on the Current Transport Properties in YBCO-Coated Conductors

We report a detailed study of the grain orientations and grain boundary (GB) networks in Y2O3 films grown on Ni-5 at.%W substrates. Electron back scatter diffraction (EBSD) exhibited different GB misorientation angle distributions, strongly decided by Y2O3 films with different textures. The subsequent yttria-stabilized zirconia (YSZ) barrier and CeO2 cap layer were deposited on Y2O3 layers by r...
