The invention relates to the technical field of
lithium-
ion batteries, in particular to an assembling method for a
lithium-
ion button type battery. The assembling method for the
lithium-
ion button type battery comprises the following steps: clamping a diaphragm by using
tweezers, slightly placing the diaphragm on a negative pole shell, and
wetting a large
diaphragm part and a small diaphragm partof a
metal lithium piece by using
electrolyte; adding a droplet of
electrolyte on the diaphragm dropwise; clamping a
pole piece by using the
tweezers, and slightly placing the
pole piece on the
electrolyte on the diaphragm; clamping a
gasket by using the
tweezers, and slightly placing the
gasket on the
pole piece; clamping one side of a positive pole shell by using the tweezers, and slightly covering the negative pole shell with the positive pole shell; slightly pressing the positive pole shell by using the tweezers; clamping an assembled battery by using the tweezers, and placing the assembled battery in an electric sealing
machine for sealing. According to the battery which is assembled by adopting the method provided by the invention, the lithium piece and the
gasket of the negative pole shell cannot be in contact with the positive pole shell by only placing one gasket on each side of the positive pole shell and the negative pole shell without foam
nickel and a spring piece, so thata
short circuit in the battery is avoided; the battery assembling time is shortened; the assembling of a button type button can be completed quickly and efficiently; the accuracy and the consistencyof the button type battery are greatly improved; the assembling method for the lithium-ion button type battery is suitable for laboratory evaluation, and is very suitable for evaluating material performance by an electrochemical method.
