Battery and terminal

Abstract

The invention discloses a battery and a terminal. The terminal comprises a body, the battery and a connection adhesive layer, wherein the body is provided with a cabin for accommodating the battery; the battery is arranged in the cabin; and the connection adhesive layer is arranged between a roll core and an aluminum-plastic film inside a battery core of the battery, and used for connecting the roll core with the aluminum-plastic film. According to the terminal provided by the invention, the connection adhesive layer is arranged between the roll core and the aluminum-plastic film inside the battery core for connecting, so that internal structural damage of the battery can be avoided, and overheat or combustion of the battery due to collision with a pole piece by displacement inside the battery core after fall of terminals such as a mobile phone during use by a user is prevented. On the other hand, the risks of heating and combustion of the battery in whole-battery fall and collision processes can be avoided effectively under the condition of not influencing battery performance or changing an internal battery design.

Description

technical field [0001] The invention relates to communication technology, in particular to a battery and a terminal. Background technique [0002] In wireless communication terminals such as GSM, CDMA, PHS, SCDMA, 3G, 4G, etc., built-in polymer batteries are usually used to effectively use the space of the battery compartment. The built-in battery is not protected by steel sheets or plastic shells. And the material is limited, the appearance is a soft package packaging method, in the battery compartment, if the adhesive is not firm or there is an impact inside the battery, it will cause damage to the internal pole piece of the battery, causing the battery to heat up or burn. In order to protect the battery, the traditional The electric core is directly put the winding core into the aluminum plastic film (the electric core includes the positive pole piece, the diaphragm, the negative pole piece, the aluminum plastic film, etc.). This structure also has the following potentia...

AI Technical Summary

Problems solved by technology

This structure also has the following potential safety hazards: when the battery is dropped, due to the impact of the whole machine, the internal winding core of the battery core will be displaced between the aluminum and plastic films, which will eventually lead to the impact deformation of the pole piece and short circuit, resulting in The internal short circuit of the battery generates heat or burns (i.e.: drop test of the whole machine-Pocke diaphragm collides with the pole piece-diaphragm folds-formation of internal short circuit-voltage drops to 0V)
