Problems solved by technology

[0005] Because the battery cells take a long time to bake and take up a long time in the oven, there is no battery production in the subsequent liquid injection process, and the number of cells to be baked is large, which seriously affects the normal production of the front and rear processes, affects the daily output of the production team, and also Seriously affect the customer's delivery time, battery cell baking has become the bottleneck process of the production line
Moreover, the battery cells take a long time to bake, and consume a lot of electricity, which increases the cost.

Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] refer to figure 1 , which is a schematic flow chart of a first embodiment of a battery manufacturing method of the present invention, the method comprising:

[0032] Step s11, making the positive electrode sheet coated with the positive electrode ingredients and the negative electrode plate coated with the negative electrode ingredients into a core, and packaging the core to form a battery core;

[0033] Step s12, expanding the cell;

[0034] Step s13, baking the flared cell;

[0035] Step s14, inject liquid into the cell;

[0036] Step s15, performing secondary packaging on the battery cell, and sealing and wrapping the battery cell to form a battery.

[0037] In the embodiment of the present invention, step s12 is set before step s13, and in step s12, the battery cell is expanded, and then the expanded battery cell is baked. Baking is carried out after ...

Abstract

The invention discloses a battery manufacturing method, comprising the following steps: making a positive electrode sheet coated with a positive electrode ingredient and a negative electrode plate coated with a negative electrode ingredient into a winding core, and packaging the winding core to form an electric core; Expanding the core; baking the expanded cell; injecting liquid into the cell; performing secondary packaging on the cell, and sealing and wrapping the cell to form a battery. In addition, the invention also discloses a high-leg baking bar for manufacturing batteries. By adopting the invention, the heat dissipation speed of the electric core is accelerated, and the baking time is shortened.

Description

technical field [0001] The invention relates to a manufacturing method, in particular to a battery manufacturing method and a high-leg baking bar for manufacturing the battery. Background technique [0002] The battery cell is a very important part of the battery, and the quality of the battery cell has a crucial impact on the quality of the battery. [0003] The moisture in the cell will react with the active materials of the positive and negative electrodes, so too much moisture will inevitably destroy its structure and affect the cycle. Therefore, the baking of the cell before liquid injection is an essential process. [0004] At present, the battery cell baking method commonly used by many companies is: the cell is not flared, and the cell is directly packed in a blue plastic box and baked in an oven. This battery baking method requires a long baking time, the battery mouth is closed, the water cannot evaporate, the battery and the battery are directly adjacent to each ...
