Abstract

The invention belongs to the battery cell processing field and especially relates to a lithium battery laminating machine double-battery-cell processing and production method. Aiming at current problems of low machining precision and a high defective rate, the invention provides the following method. The method comprises the following steps of S1, inputting sizes of positive and negative pole pieces which need to be machined into a computer, and modeling on the computer; S2, simulating lamination of the positive and negative pole pieces, and recording simulated data; S3, connecting the pole pieces on two sides through tabs, placing a diaphragm, placing diaphragm volumes on the left, right, positive and negative sides, and adding the two diaphragm volumes on the front, back, left and rightsides; and S4, inputting the data in the S2 into a lamination machine through input equipment, conveying the pole pieces by the lamination machine through a lamination clamping and conveying device according to the received data, and carrying out lamination. According to the invention, a processing process of a battery cell can be accurately controlled, the defective rate can be effectively reduced, production efficiency is improved, and a reliable basis is provided for subsequent production.

Description

technical field [0001] The invention relates to the technical field of cell processing, in particular to a method for processing and producing double cells of a lithium battery lamination machine. Background technique [0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, M.S.Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream now. [0003] Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Li-ion batteries do not contain metallic lithium and are ...
