[0002] The commonly used battery in electronic cigarettes is a lithium battery. The Chinese patent with the current publication (announcement) number CN205282592U discloses a lithium-ion electronic cigarette battery, including an electronic cigarette shell, an outer cover, a positive electrode sheet, a negative electrode sheet, a protective cover, a positive electrode ear, a negative electrode ear, and a diaphragm. The lithium-ion electronic cigarette battery first sandwiches the diaphragm between the positive electrode sheet and the negative electrode sheet, so that the four sides of the positive electrode sheet and the negative electrode sheet are aligned, and the positive electrode sheet and the negative electrode sheet are both placed horizontally, and then the positive electrode ear and the negative electrode ear are placed on the top of the positive electrode sheet and the bottom of the negative electrode sheet respectively, and the positive electrode sheet and the negative electrode sheet are longitudinally wound through the diaphragm, so that the diaphragm isolates the positive electrode sheet and the negative electrode sheet from each other. Since the positive electrode sheet and the negative electrode sheet are longitudinally wound and isolated by the diaphragm, not only can the positive electrode ear and the negative electrode ear be well avoided, the amount of diaphragm is reduced, thereby reducing the weight of the battery, and it is convenient for the diaphragm to be wound around the outer wall of the positive electrode sheet and the negative electrode sheet, thereby reducing the processing difficulty, improving the processing efficiency, and reducing the cost of the battery.

[0031] The sealing rubber plug 3 is encapsulated inside one end of the aluminum shell 1 which is an open structure;

[0032] Among them, the capacitor lithium ion battery cell 2 is encapsulated in the aluminum shell 1 through the sealing plug 3, and the capacitor lithium ion battery cell 2 has a positive guide needle 9 and a negative guide needle 10, the positive guide needle 9 is electrically connected to the positive electrode sheet inside the capacitor lithium ion battery cell 2, the negative guide needle 10 is electrically connected to the negative electrode sheet inside the capacitor lithium ion battery cell 2, and the ends of the negative guide needle 10 and the positive guide needle 9 away from the capacitor lithium ion battery cell 2 both penetrate the sealing plug 3 and are exposed.

[0033] The capacitive lithium-ion battery using the above technical solution is mainly composed of an aluminum shell 1, a sealing plug 3 and a capacitive lithium-ion battery cell 2.

Then, the sealing plug 3 is sealed by a machine to encapsulate the sealing plug 3 and the capacitive lithium-ion battery cell 2 together in the interior of the aluminum shell 1, which can greatly improve production efficiency. What is more important is that the mutual cooperation between the aluminum shell 1 and the sealing plug 3 can prevent the capacitive lithium-ion battery cell 2 from leaking, and the safety performance is good, which is particularly suitable for powering electronic cigarettes.
