Application: Battery-fixing bonding tape and mobile terminal (Patent ID: US20240213637A1)
The patent filed by TDK Corp describes a bonding tape for batteries that includes a first adhesive layer, a substrate layer, a second adhesive layer, and an original film. The first adhesive layer is bonded to the battery, while the second adhesive layer has a first region with the original film and a second region bonded to a battery compartment. The tape aims to reduce overall thickness, improve energy density, enhance anti-drop performance, and increase drop window pass rate.
The claims detail specific aspects of the bonding tape, such as the configuration of layers, the presence of a through-hole in the original film, the ratio of thickness between adhesive layers, and the projected areas of different components. Additionally, the claims outline conditions related to the thickness of adhesive layers, the shape of the second region, and the bonding force between the layers and battery components. The patent also extends to the use of the bonding tape in a mobile terminal, specifying requirements for fixing the battery in the terminal and ensuring proper distances between components for effective bonding.
