Problems solved by technology

However, during production, when lithium-ion polymer batteries are formed in high-temperature fixtures, there are frequent occurrences of ultra-thin and ultra-thick cells due to improper pressure control of the pressing plate, and dark marks on the pressing plate due to frequent pressing of cells of different sizes. The problem of lithium deposition due to uneven local force on the battery cell affects the quality of the battery
[0003] At present, there is no effective solution to the problems of ultra-thin and ultra-thick batteries caused by the formation of high-temperature fixtures and local lithium deposition in the batteries caused by dark marks on the pressing plate at home and abroad.

Embodiment Construction

[0019] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0020] like figure 1 and figure 2 As shown, the embodiment of the present invention provides a lithium-ion polymer battery limiting forming fixture 1, which is used for fixed limiting during battery forming. The battery limiting fixture 1 includes an installation body 11 for installing and fixing the battery. The installation body 11 is provided with an accommodation groove 12 for accommodating the battery. When assembling, the battery is placed in the accommodation groove 12, and the installation body 11 is covered A cover plate 13 for fastening the battery is provided. In this way, by pressin...

Abstract

The invention is applicable to the technical field of battery manufacturing, and discloses a limiting and formation clamp for a lithium ion polymer battery used for fixing and limiting in battery formation. The limiting and formation clamp comprises a mounting body used for mounting and fixing batteries, wherein accommodating grooves used for accommodating batteries are formed in the mounting body; a cover plate used for fastening the batteries is mounted on the mounting body; and a limiting structure for preventing the batteries from loosening or from being over-extruded is arranged between the cover plate and the mounting body. The limiting and formation clamp for the lithium ion polymer battery provided by the invention is simple in structure, capable of effectively solving the problems of ultra-thin or ultra-thick cells and partial lithium separating-out, and capable of ensuring battery product quality.

Description

technical field [0001] The invention belongs to the technical field of battery manufacturing, and in particular relates to a clamp for limiting and forming a lithium ion polymer battery. Background technique [0002] Lithium-ion polymer batteries have the advantages of high voltage, high specific energy, many cycle times, long storage time, and small size, and have been widely used in portable electronic devices. However, during production, when lithium-ion polymer batteries are formed in high-temperature fixtures, there are frequent occurrences of ultra-thin and ultra-thick cells due to improper pressure control of the pressing plate, and dark marks on the pressing plate due to frequent pressing of cells of different sizes. The problem of lithium deposition due to uneven local force on the battery cell affects the quality of the battery. [0003] At present, there is no effective solution at home and abroad to the problems of ultra-thin and ultra-thick cells caused by high...
