Viscose glue lithium ion battery and manufacturing method thereof

Abstract

The invention provides a viscose glue lithium ion battery. The viscose glue lithium ion battery comprises a first electrode, a second electrode and an aluminum foil, wherein the first electrode and the second electrode are wound together; the aluminum foil is arranged between the first electrode and the second electrode; the first electrode and the aluminum foil are bonded together through viscose glue, and are fixed together by pressing through an upper module and a lower module of a press. A manufacturing method of the viscose glue lithium ion battery comprises the following steps: coating the upper surface of the aluminum foil with the viscose glue; coating the lower surface of the first electrode with the viscose glue; bonding the aluminum foil and the surface coated with the viscose glue of the first electrode together; pressing the aluminum foil and the first electrode by the press; winding the first electrode, the second electrode and the aluminum foil to obtain the viscose glue lithium ion battery. The viscose glue lithium ion battery provided by the invention has the advantages of high security, high stability and high cycle performance; moreover, the manufacturing method has high efficiency, contributes to effect saving of the production and machining cost, and has a great economical use value.

Description

technical field [0001] The invention relates to the technical field of lithium-ion battery design, in particular to a viscose-type lithium-ion battery and a preparation method thereof. Background technique [0002] Lithium-ion battery: It is a secondary battery (rechargeable battery) that mainly relies on lithium ions to move between the positive and negative electrodes to work. During the charging and discharging process, Li + Intercalation and deintercalation back and forth between two electrodes: when charged, Li + It is deintercalated from the positive electrode, inserted into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. Batteries generally use materials containing lithium as electrodes, which are representatives of modern high-performance batteries. Lithium-based batteries are divided into lithium batteries and lithium-ion batteries. Cell phones and notebook computers use...

AI Technical Summary

Problems solved by technology

Cell phones and notebook computers use lithium-ion batteries, commonly known as lithium batteries, but real lithium batteries are rarely used in daily electronic products due to their high risk. At present, lithium-ion batteries in the prior art are being prepared There are often certain defects in the process. For example, the foil guide of the battery is nailed and turned over, which is easy to damage the battery material itself, causing problems such as burrs, and even the product is easy to explode, which needs further improvement.
