Such FET structures may be made by patterning an IC die to outline one or more regions of crystalline semiconductor material in the outline of a fin or nanosheet; converting the outlined regions to π-Semi having essentially vertical walls; further converting the outlined regions to π-Semi having flared walls; then selecting one of these options: etching the π-Semi to define fins, etching the π-Semi to define nanosheets with a residual π-Semi floor, or etching the π-Semi to define nanosheets with no residual π-Semi floor; and forming a gate structure over the fins or around the nanosheets. Additional steps and structures (e.g., formation of source and drain regions, formation of contacts, metallization layers, vias, etc.) may then be performed.

A secondary battery includes an electrode wound body and an outer package can containing the electrode wound body. The electrode wound body includes a stacked body including a positive electrode, a negative electrode, and a separator and being wound along a longitudinal direction thereof, and has a through hole in a width direction. The positive electrode includes a positive electrode current collector, and a positive electrode active material layer provided thereon. The positive electrode active material layer includes a first thin part, a thick part, and a second thin part. The thick part has a thickness greater than a thickness of the first thin part and is adjacent to the first thin part in the longitudinal direction. The second thin part has a thickness smaller than the thickness of the thick part and is positioned on an opposite side of the thick part to the first thin part.

A secondary battery includes an electrode wound body and an outer package can containing the electrode wound body. The electrode wound body includes a stacked body including a positive electrode, a negative electrode, and a separator and being wound along a longitudinal direction thereof, and has a through hole provided through the electrode wound body in a width direction. The positive electrode includes a positive electrode current collector extending in both the longitudinal direction and the width direction, and a positive electrode active material layer provided thereon. The positive electrode active material layer includes a first thin part, a thick part, and a grooved part. The thick part has a thickness greater than a thickness of the first thin part and is adjacent to the first thin part in the longitudinal direction. The grooved part is positioned between the first thin part and the thick part.
