All-solid-state batteries with inorganic solid electrolytes (SEs) are recognized as an ultimate goal of rechargeable batteries because of their high safety, versatile geometry, and good cycle life. Compared with thin-film batteries, increasing the reversible capacity of bulk-type all-solid-state batteries using electrode active material particles is difficult because contact areas at solid–soli...

Abstract The forming limit diagram (FLD) of high-purity niobium sheets used for the manufacturing superconducting radiofrequency (SRF) cavities is presented. Marciniak (in-plane) test was with blanks a thickness 1 mm and blank carriers annealed oxygen-free electronic (OFE) copper. A high formability measured, an approximate true major strain at necking plane 0.44. likely caused by its rate sens...
