The two-part composition includes a first part and a second part. The first part includes a vinyl-substituted polysiloxane, a hydrosilylation catalyst, expandable graphite comprising moisture, and first polymeric microspheres having been at least partially coated with inorganic filler. The second part includes a second vinyl-substituted polysiloxane, a hydrosilyl-substituted polysiloxane, and second polymeric microspheres having been at least partially coated with flame-retardant inorganic filler. The two-part composition is useful, for example, for curing into a sealant and making an assembly. The assembly has a first substrate and a second substrate with a cured product of the two-part composition in contact with the first substrate and the second substrate. Methods of making a sealant and an assembly are also described.

Embodiments of this application provide a middle frame, a battery cover, and an electronic device. The electronic device may include a mobile or fixed terminal with an edge frame or a housing, such as a mobile phone, a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a handheld computer, a walkie-talkie, a netbook, a POS machine, a personal digital assistant (PDA), an event data recorder, a wearable device, a virtual reality device, a wireless USB flash drive, a Bluetooth speaker/headset, or a vehicle-mounted device. Two types of materials: ceramics and plastic, are used to form a middle frame and a battery cover, thereby reducing a weight of the electronic device. This resolves a problem that is of a relatively large weight of an existing electronic device and that is caused when a pure ceramic middle frame and a pure ceramic battery cover are used in the electronic device.

A battery pack assembly or enclosure comprises one or more batteries having an electrochemical cell and an enclosure having at least an outer wall configured to create a sealed volume of space substantially around the batteries. An atmosphere of the volume of space comprises gas having a thermal conductivity less than 0.018 watts per meter per degree Celsius. This atmosphere of gas provides an insulative layer between the outer wall of the enclosure and the batteries. With this insulative layer, the battery pack assembly can be subjected to autoclaving without damaging the batteries. The battery pack assembly can be used to power surgical tools or other devices that are subjected to autoclaving.

A battery assembly includes a cell stack including a plurality of battery cells stacked together, a busbar assembly coupled to the cell stack and including a busbar electrically connected to an electrode lead of at least one of the battery cells, a plate unit configured to cover at least a portion of a side surface of the cell stack, a sensing unit coupled to the busbar assembly and disposed outside of the cell stack, and a cell monitoring unit installed on the plate unit and coupled to the sensing unit.

The present invention relates to an apparatus and method for the localized capture, storage and specialized use of power generated from natural sources, such as solar power or hydropower. The apparatus can be used, for example, or in or near commercial or residential buildings, vehicles, marine vessels, a wind farm turbine tower, or in a solar park or photovoltaic power station, or anywhere there is a requirement for localized power generation, localized storage and wider distribution of power.

A battery module for a vehicle, in particular for an aircraft, comprises two end plates and a cell stack comprising an arrangement of several interconnected battery cells, in particular pouch cells, that are arranged in a row along a stacking direction, wherein the cell stack is sandwiched between the two end plates in the stacking direction, wherein the battery module further comprises a separate tube-like enclosure comprising a heat insulating material, the tube-like enclosure having a front opening and a back opening that are closed by the end plates, so that the tube-like enclosure and the two end plates form a housing in which the cell stack is accommodated.

A battery pack includes a cell assembly unit including a plurality of battery cells and a bus bar configured to electrically connect the plurality of battery cells, a frame unit accommodating the cell assembly unit, and a bracket unit fixing the cell assembly unit to the frame unit. The bracket unit and the frame unit form a flow path through which a gas is discharged. A reverse flow prevention member is disposed between the bus bar and the bracket unit. The reverse flow prevention member includes a plurality of gas permeation holes, each of which extends from one end facing the bus bar and leads to another end facing the flow path.

The present disclosure relates to a multilayer composite that may include a first porous layer, and a first barrier layer overlying the first porous layer. The first barrier layer may include a polyaramid material, a polyimide material, or any combination thereof. The multilayer composite may have a flame resistance rating of at least about 180° C. and a 50% strain compression rating of not greater than about 600 kPa.
