In some embodiments of the present invention a method includes: obtaining a first aluminum alloy sheet formed from rolling a first ingot of a 3xxx or a 5xxx series aluminum alloy, wherein, prior to rolling, the first ingot has been heated to a sufficient temperature for a sufficient time to achieve a first dispersoid f/r of less than 7.65; and forming a container precursor from the first aluminum alloy sheet, wherein when the first aluminum alloy sheet is formed into the container precursor, the container precursor has less observed surface striations and ridges as compared to a container precursor formed from a second aluminum alloy sheet rolled from a second ingot having a second dispersoid f/r value of 7.65 or greater.

Aluminum sheet with enhanced formability and an aluminum container made from aluminum sheet

The present disclosure relates to energy storage devices having: a sealed container configured to house a plurality of energy storage devices and enable electrical communication via terminals of the sealed container and a vent located on a periphery of the sealed container. The vent generally comprises a vent panel; a countersink located adjacent the vent panel; at least one score located in the countersink; a buckling initiator at least partially located on the countersink, where the buckling initiator is configured to intersect with the at least one score; and a hinge portion attached to the vent panel, where the hinge portion is positioned opposite the buckling initiator.

Energy storage device and related methods

New magnesium-zinc aluminum alloy bodies and methods of producing the same are disclosed. The new magnesium-zinc aluminum alloy bodies generally include 3.0-6.0 wt. % magnesium and 2.5-5.0 wt. % zinc, where at least one of the magnesium and the zinc is the predominate alloying element of the aluminum alloy bodies other than aluminum, and wherein (wt. % Mg)/(wt. % Zn) is from 0.6 to 2.40, and may be produced by preparing the aluminum alloy body for post-solutionizing cold work, cold working by at least 25%, and then thermally treating. The new magnesium-zinc aluminum alloy bodies may realize improved strength and other properties.

Heat treatable aluminum alloys having magnesium and zinc

In some embodiments of present disclosure, a method includes: obtaining an aluminum sheet comprising a 3xxx or a 5xxx alloy having a tensile yield strength as measured in the longitudinal direction of 27-33 ksi and an ultimate tensile strength; wherein the ultimate tensile strength minus the tensile yield strength is less than 3.30 ksi (UTS-TYS&#x3c;3.30 ksi); and forming a container having a dome from the aluminum sheet.
