Problems solved by technology

However, the current lithium-ion battery is generally formed by assembling the protective plate and the battery cell, and the components on the protective plate are usually exposed, so problems such as battery failure due to component damage are prone to occur during assembly.
In this regard, an additional bracket is generally used to protect the protective plate, but the setting of the bracket will affect the energy density of the battery

Abstract

The present application provides a battery, including an electrode assembly and a casing for accommodating the electrode assembly. The battery also includes an extension and a circuit board. The extension part is connected to the housing and together with the housing forms a receiving space. The circuit board is accommodated in the accommodation space and electrically connected to the electrode assembly. The battery in the present application forms an accommodating space for accommodating the circuit board by providing an extension part to cooperate with the casing to protect the circuit board and avoid damage to the circuit board due to transportation or testing. In addition, compared with the traditional solution of protecting the circuit board by the bracket, the space occupied by the extension part is smaller, so that while protecting the circuit board, the energy density of the battery is also greatly improved. The present application also provides an electronic device with the battery.

Description

Battery and electronic device having the same technical field [0001] The present application relates to the field of electrochemistry, and in particular to batteries and electronic devices having the batteries. Background technique [0002] Lithium-ion batteries are widely used due to their high energy density, high reliability, and many cycles of use. It is used in mobile terminals, smart mobile homes, smart aircraft and other fields. Therefore, in order to meet the increasing number of products in different fields With the increased functional requirements, the requirements for batteries have also increased. However, current lithium-ion batteries are generally composed of protective plates and cells. Assembly is formed, and the components on the protection board are usually exposed, so it is easy to cause battery failure due to component damage during assembly. equivalence issues. In this regard, an additional bracket is generally used to protect the protective pl...
