An electrical device, having a feedthrough through a housing part which has a material thickness T of the housing of the device and is made of metal. The metal being iron, iron alloys, iron-nickel alloys, iron-nickel-cobalt alloys, KOVAR, steel, high-grade steel, aluminum, aluminum alloys, AlSiC, magnesium, magnesium alloys, titanium or titanium alloys. The housing part having at least one opening, wherein the opening receives a contact element, being a conductor consisting of a conductive material in a glass or glass ceramic material. The housing part has a collar in the region of the opening and thus forms an inner wall of the feedthrough opening having a height H, which is greater than material thickness T, wherein glazing length EL of the glass or glass ceramic material preferably corresponds to height H.

A battery assembly and an electronic cigarette using the battery assembly are provided. The battery assembly comprises a main body and a rear cover fixedly installed to the main body. One end of the main body is provided with a connecting portion fixedly electrically connected to an external load, and the other end thereof is provided with an inner cavity for accommodating an electronic component. The rear cover is fixedly installed to the main body and covers the inner cavity. One end of the main body far from the connecting portion is provided with an extension toward the rear cover, and the extension covers the end of the rear cover far from the connecting portion, effectively preventing the phenomenon that a housing far from the end of a suction port is damaged by impact when the electronic cigarette is dropped.

This disclosure details exemplary battery pack designs for use in electrified vehicles. An exemplary battery pack may include an enclosure assembly that houses one or more battery arrays. An impact protection shroud is mounted to a portion of at least one of the battery arrays. A battery sensitive component is at least partially covered by the impact protection shroud. The impact protection shroud is configured to establish minimum clearances relative the battery sensitive component and to redirect loads away from the battery sensitive component, thereby protecting the battery sensitive component during vehicle impact loading events.

A secondary battery is disclosed. According to the present invention, when an internal pressure exceeding a certain level occurs, current may be interrupted to stop an operation of the secondary battery, thereby preventing the secondary battery from being ignited or exploded by the increase in internal pressure of the secondary battery and improving safety of the secondary battery.

The present application provides a battery and an electronic device thereof. The battery comprises: a electrode assembly having at least one separator protrusion; a package bag for accommodating the electrode assembly; and a buffer layer arranged between the electrode assembly and the package bag; wherein the buffer layer is further arranged on the at least one separator protrusion. The purpose of the present application is to provide a battery and an electronic device thereof which are capable of improving the drop resistance performance of the battery and improving the safety performance of its use.
