Embodiment Construction

[0038] In order to enable those skilled in the technical field to which the application belongs to understand the application more clearly, the technical solutions of the application will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0039] Generally, the shape of the button battery cell determines the shape of the final button battery. In order to ensure that the shape of the ever-growing bluetooth mobile device will not be limited by the shape of the soft-pack button lithium-ion battery used, but also provide as much power as possible and improve the battery life, an optional In the example, such as Figure 1 ~ Figure 2 As shown, a battery cell assembly 1 for a soft-pack button lithium ion battery is proposed, including: a positive electrode sheet 11, a negative electrode sheet 12, a positive electrode tab 14, a negative electrode tab 15 and a diaphragm 13;

[0040] The positive electrode sheet 11 and the negative...

Abstract

The invention discloses a battery cell assembly for a soft package button lithium ion battery. The battery cell assembly comprises a positive plate, a negative plate, a positive tab, a negative tab and a diaphragm, wherein the positive plate and the negative plate are laminated and then wound into a cylindrical battery cell, and the diaphragm is arranged between the positive plate and the negativeplate; the cylindrical battery cell is provided with a bottom surface, a top surface and side surfaces, and the bottom surface or the top surface is in the shape of an axial section of a capsule; thelength of the bottom surface is within 20mm, and the width of the bottom surface is less than the length; the height of the side surface is within 10mm; the positive tab is fixedly connected to the positive plate, and the negative tab is fixedly connected to the negative plate. By using the cylindrical battery cell, a capsule-shaped soft package button lithium ion battery of which the appearanceis similar to that of a common medicine capsule can be prepared; the shape requirement of the continuously developed Bluetooth mobile equipment for the battery can be met, and the electricity storagecapacity equivalent to that of a button battery of a common cylinder specification can be provided at the same time, so that the endurance time requirement of the Bluetooth mobile equipment is also considered.

Description

technical field [0001] The present application relates to the technical field of soft-packed button batteries, in particular to a cell assembly for a soft-packed button lithium-ion battery and a button battery. Background technique [0002] Generally speaking, the packaging of lithium-ion batteries is divided into two categories, one is soft pack batteries, and the other is metal shell batteries. Soft-packed button lithium-ion battery refers to the button-type lithium battery whose battery case is formed and heat-sealed with aluminum-plastic film. It is different from steel-cased lithium-ion batteries. The main difference is the soft-packed case. Button batteries are also known as button batteries, and one of the main uses of the pouch lithium-ion battery is to power Bluetooth mobile devices. For example, the most common device is a Bluetooth headset. The button batteries currently used in Bluetooth headsets mainly include LIR940, LIR1040, LIR1240, LIR1654, etc., and their ...
