Battery pack

The secondary battery cells are disposed in parallel in such postures that side surfaces of cylindrical shapes face each other in an internal space of a housing case, and are separated from each other with a longitudinal partition plate interposed between the secondary battery cells. A pair of ribs are provided on an inner surface of the housing case to hold the longitudinal partition plate. The longitudinal partition plate disposed between the pair of ribs is held in the housing case. A gap between the pair of ribs and the longitudinal partition plate is filled with a flame-retardant adhesive material.

TWO-PART SILICONECOMPOSITION AND SEALANT AND ASSEMBLY MADE THEREFROM

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.

MIDDLE FRAME, BATTERY COVER, AND ELECTRONIC DEVICE

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.
