Description

Soft packet of lithium cell of simplex position top seal side seal all-in-one

Technical Field

The utility model relates to a battery packaging technology field, concretely relates to soft packet of lithium cell of simplex position top seal side seal all-in-one.

Background

The soft package lithium battery is a liquid lithium ion battery which is sleeved with a polymer shell and is structurally packaged by an aluminum plastic film. An aluminum-plastic packaging film (referred to as an aluminum-plastic film for short) is composed of three layers: nylon layer, aluminium foil layer and PP (polypropylene) layer. The nylon layer ensures the appearance of the aluminum plastic film and ensures that the film cannot deform before the lithium ion battery is manufactured. The aluminum foil layer is formed by a layer of metal aluminum, and the function of the aluminum foil layer is to prevent water from permeating. Lithium ion batteries are very feared to water, and generally require that the water content of a pole piece is in PPM level, so that a packaging film must be capable of blocking the penetration of moisture. Nylon is not waterproof and cannot play a role in protection. And the metal aluminum can react with oxygen in the air at room temperature to generate a layer of compact oxide film, so that water vapor cannot permeate into the metal aluminum, and the interior of the battery cell is protected. The aluminum foil layer also provides the punching plasticity when the aluminum plastic film is formed. PP is the abbreviation for polypropylene, and this material has the property of melting at temperatures of more than one hundred degrees celsius and of being viscous. Therefore, the heat sealing of the battery mainly depends on that the PP layer is melted and bonded together under the heating action of the seal head, then the seal head is removed, and the PP layer is solidified and bonded after being cooled.

The lithium battery has high requirements on water content, and the packaging quality of the soft package battery can be ensured only by strictly controlling the pressure, the heating temperature and the time between the upper end socket and the lower end socket in the packaging process of the soft package lithium battery.

The top sealing and side sealing implementation method of the traditional soft package lithium battery packaging equipment comprises the following steps: firstly, fixing a lithium battery pack to be packaged on a clamp, then pushing a jig between hot-melting seal heads, and then folding an upper seal head and a lower seal head which have certain temperature, so that the aluminum-plastic film and the aluminum-plastic film, and the aluminum-plastic film and the tab adhesive are hot-melted and bonded. But present lithium cell top side, side seal tool are mostly manual operation and move the operation at two hot melt head stations of top seal, side seal, and are more time-consuming and energy-consuming. The automatic multi-station packaging equipment is adopted, the mechanism is complex, the cost is high, and in the moving process of the jig carrying the lithium battery pack, the problems of displacement, accumulated error, poor traceability of production batch numbers of different jigs and the like caused by vibration exist, so that potential quality hazards are brought to battery packaging; and when the lithium battery packages with different sizes are manufactured, the jigs with various specifications are required to be manufactured generally, so that the operation efficiency is reduced, and the manufacturing cost of the lithium battery is improved. Related designs can be found in chinese patents 200720053226.3, 201620150647.7, 201620531697.X, 201822139055.7, 201922438774.3, 201922446902.9, etc.
