Description

Lithium battery cell disassembling mechanism

Technical Field

The utility model relates to the technical field of lithium batteries, in particular to a lithium battery cell disassembling mechanism.

Background

The lithium battery is a battery using a nonaqueous electrolyte solution, and using lithium metal or a lithium alloy as an anode material. Unlike lithium ion batteries, the former is a primary battery and the latter is a rechargeable battery. The chemical characteristics of lithium metal are very active, so that the processing, storage and use of lithium metal have very high requirements on environment [1], and therefore, lithium batteries have not been applied for a long time. With the development of microelectronic technology at the end of the twentieth century, miniaturized devices are increasing, and high requirements are put on power supplies, so that lithium batteries enter a large-scale practical stage.

The battery core is divided into three types of an aluminum shell battery core, a soft package battery core (also called as a polymer battery core) and a cylindrical battery core. In general, the battery of the mobile phone adopts an aluminum shell battery core, the digital products such as Bluetooth and the like mostly adopt a soft package battery core, and the battery of the notebook computer adopts a serial-parallel combination of cylindrical battery cores.

When disassembling the cell modules, the structural adhesive between adjacent cells needs to be destroyed to divide the cell modules into individual cells. At present, a violent dismantling method is generally adopted: the wedge blocks are manually plugged between adjacent cells and then knocked with a hammer to separate the cell modules. The method is low in efficiency through manual disassembly. Moreover, the disassembly process is easy to damage disassembly personnel and the battery cell, and even leads to scrapping of the battery cell. In view of this, we propose a lithium battery cell disassembling mechanism.
