For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to the specific circumstances.

[0031] like Figures 1-2 As shown, an embodiment of the utility model provides a lithium-ion battery for an electronic cigarette, including a battery body 100 , a tab 200 , a metal cover 300 and an insulating sleeve 400 .

[0032] The battery body 100 is cylindrical, and both ends of the battery body 100 are provided with flat ends 110, and the two pole ears 200 extend outward from the inside of the battery body 100 through the corresponding flat ends 110, and the two pole ears 200 are the positive pole ear 200 and the negative pole ear 200.

[0033] Furthermore, the flat end 110 is bent to abut against the end face of the battery body 100, and the tab 200 is bent to form a bent portion 210 abutting against the end face of the battery body 100. An insulating pad 500 is arranged between the bent portion 210 and the flat end 110 to prevent a short circuit. Specifically, the insulating pad 500 is a green shell paper insulating pad 500.

[0034] Both ends of the battery body 100 are covered with the metal cover 300 adapted thereto. Specifically, the metal cover 300 is made of aluminum.

[0035] Furthermore, the interior of the metal cover 300 is provided with a metal sheet 310 that abuts against the inner wall of the upper end of the metal cover 300. The metal sheet 310 is adapted to the interior of the metal cover 300. The metal sheet 310 is provided with a protrusion 311 protruding toward the battery body 100. The bent portion 210 abuts against the protrusion 311 to improve stability, thereby ensuring that the bent portion 210 and the metal cover 300 can be electrically connected. When in use, power can be supplied by contacting the two metal covers 300 without welding, which is convenient for assemblers to assemble and convenient for users to disassemble and classify for recycling later.

Specifically, the end of the protrusion 311 facing the battery body 100 is higher than the end of the extension wall 312 facing the battery body 100, so as to avoid the extension wall 312 interfering with the protrusion 311.

[0037] In one embodiment, the insulating sleeve 400 wraps the battery body 100 and the metal cover 300, and the end surfaces of the insulating sleeve 400 and the metal cover 300 form a conductive area 600 connected to the outside, thereby ensuring the stability of the lithium-ion battery used in the electronic cigarette during use and making the installation of the metal cover 300 more stable.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
