Problems solved by technology

[0002] The existing battery assembly method, such as the assembly method of the button-type lithium-ion battery, adopts the assembly method of fixing the positive electrode piece in the positive electrode case, which is not only difficult to operate, but also has a low assembly pass rate, and the positive electrode piece is easily placed in the positive electrode case. Position offset occurs, and an excessive position offset distance will reduce the performance of the battery; at the same time, during the sealing process of the battery using this assembly method, the electrolyte in the battery is easy to seep out of the seal, which increases the internal resistance of the battery. further degrades the performance of the battery

Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or t...

Abstract

The invention provides a battery assembly method, which comprises: installing a positive electrode sheet in a negative electrode shell; adding an electrolytic solution on the positive electrode sheetin a dropwise manner to form a first electrolytic solution layer; covering the first electrolytic solution layer by using a separation membrane; arranging a lithium sheet on the surface, away from thepositive electrode sheet, of the separation membrane; and covering with a positive electrode shell, and fitting with the negative electrode shell. The present invention further provides a battery assembled by using the battery assembly method, wherein the battery comprises a negative electrode shell, a positive electrode sheet, a first electrolytic solution layer, a separation membrane, a lithiumsheet and a positive electrode shell, the positive electrode sheet is fixed in the negative electrode sheet, the first electrolytic solution layer is arranged on the positive electrode sheet, the separation member covers the first electrolytic solution layer, the lithium sheet is arranged on the surface, away from the positive electrode sheet, of the separation membrane, and the positive electrode shell covers and fits the negative electrode shell. According to the present invention, the performance of the assembled battery is improved through the battery assembly method; and the battery hasexcellent discharge performance.

Description

technical field [0001] The invention relates to the field of battery technology, in particular to a battery assembly method and a battery assembled using the method. Background technique [0002] The existing battery assembly method, such as the assembly method of the button-type lithium-ion battery, adopts the assembly method of fixing the positive electrode piece in the positive electrode case, which is not only difficult to operate, but also has a low assembly pass rate, and the positive electrode piece is easily placed in the positive electrode case. Position offset occurs, and an excessive position offset distance will reduce the performance of the battery; at the same time, during the sealing process of the battery using this assembly method, the electrolyte in the battery is easy to seep out of the seal, which increases the internal resistance of the battery. further degrades the performance of the battery. Contents of the invention [0003] In view of this, it is ...
