Embodiment Construction

[0017] In order to allow those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described below in conjunction with the accompanying drawings.

[0018] A lithium battery packaging method is characterized in that comprising the following steps:

[0019] The first step is to weld the battery cell 1 and the protective plate 2; the battery cell can be a single-segment or multi-series battery pack, the positive and negative nickel sheets of the battery pack, soft board (FPC), wire Spot welding or soldering with the protection plate, the cell group is multi-series parallel, the cells need to be connected in series and parallel welding first, and then welded with the protection plate after the series and parallel welding of the cells, the cell and the protection plate The sequence of welding needs to be welded in the order from low voltage to high voltage;

[0020] The second step is to put the welded bat...

Abstract

The invention provides a lithium battery encapsulating method. The lithium battery encapsulating method is characterized by comprising the following steps: step I, welding a cell with a protective plate according to a welding sequence of low voltage to high voltage; step II, installing the well-welded cell and protective plate into a battery rubber frame, firstly positioning and assembling the protective plate and the battery rubber frame, and then horizontally placing the cell into the battery rubber frame without fixation; step III, filling all gaps inside the entire battery pack in an injection molding manner at low pressure and low temperature by adopting a hot runner for the well-placed cell, protective plate and battery rubber frame. The hot runner technology is applied to the battery encapsulation process, the encapsulated battery has the effects of high temperature resistance, shock absorption, moisture resistance, water resistance, chemical corrosion resistance and the like, no waste material such as runner and water gap is produced in the injection molding process, the waste material produced in the production process can be effectively reduced, the encapsulation cost of the battery is effectively reduced, the encapsulation process is simple, the production efficiency is high, and the market competitive advantage can be improved.

Description

technical field [0001] The invention relates to the technical field of lithium battery packaging, in particular to a lithium ion battery packaging method using a hot runner method and heat capacity injection molding under low-pressure and low-temperature conditions. Background technique [0002] With the application and popularization of various high-end portable electronic devices, people's requirements for battery capacity, safety performance and humanization are constantly improving. The existing lithium battery packaging method uses low-pressure injection molding packaging, which is through ordinary flow channels Injection molding, the melt temperature is generally between 190° and 210°, it can only be used for injection molding of lithium-ion batteries with aluminum shells and lithium polymer batteries with protective surfaces on the cell surface, and the flow generated during the injection molding process Channels, nozzles, etc., resulting in large material loss, high ...
