Problems solved by technology
[0006] Second, the installation and fixing structure between the battery core and the battery case is relatively complicated, and a special structure for mutual cooperation needs to be designed between the two to ensure that the battery core and the battery case are firmly fixed together. And the positive and negative terminals can be drawn from the battery core to the outside of the battery case
The design of this matching structure increases the overall manufacturing cost of the battery; and, since additional steps are required to combine the battery core and the battery case, the complexity of the process and procedures is increased

Abstract
The invention relates to a method for manufacturing a bipolar level battery and the bipolar level battery. The method comprises the following steps: providing a battery core of a horizontal battery; putting the battery cell as an embedded part into an injection mold; a battery shell is formed in an injection mold through injection molding, the battery shell surrounds the battery core, the battery shell and the battery core are combined into a whole, and a circulation channel is formed between the battery core and the battery shell so that the electrolyte can circulate in the circulation channel; a top cover and a bottom cover are respectively arranged on the top surface and the bottom surface of the battery shell and are sealed, so that a sealed space is formed in the battery shell and is used for storing electrolyte; and injecting an electrolyte into the battery case. According to the horizontal battery manufactured by the method, the battery core and the battery shell can be directly, conveniently and stably fixed together, and the sealing among the battery monomers of the battery core can be conveniently and effectively realized.
Description
technical field [0001] The present application relates to the field of batteries, in particular to a method for manufacturing a horizontal battery and a horizontal battery manufactured by the method. Background technique [0002] In today's society, batteries have been widely used in various fields. Due to the different application occasions, the types of batteries are also various. Among them, as a kind of stacked battery, the horizontal battery is usually used as a large-capacity battery because it can contain multiple battery cells, and can be used for starting automobiles, ships, construction machinery, aircraft, locomotives, etc. , backup power supply, forklift and other fields. [0003] The existing horizontal battery manufacturing process is to separately manufacture the battery core of the horizontal battery (multiple single battery clusters formed by stacking and fixing bipolar plates, positive single plates, negative electrode plates, separators, etc.) and the ba...
