According to the law of conservation of energy, a battery with high internal resistance has part of the energy converted into heat energy and lost in the discharging process of the battery except for the conversion of electric energy. The cylindrical polymer battery for the electronic cigarette is limited by the appearance and the characteristics of tab glue packaging, and the internal structure of the single-core coil is difficult to break through the restriction of internal resistance. The electrode lugs of the traditional lithium battery are independently welded on an aluminum foil or a copper foil coated with a positive electrode material or a negative electrode material, only one electrode lug is arranged on each electrode lug, and in the actual charging process, the welding electrode lug has large resistance, small discharge current and poor multiplying power performance, and the battery generates heat seriously and has potential safety hazards.
In order to overcome the technical problems, various types of batteries in the market are designed to change the internal structure. For example, the three-core and four-core parallel connection mode inside the aluminum-shell battery; designing a lamination of the soft package battery; the multi-tab of the steel shell battery, etc., but the cylindrical polymer battery for the electronic cigarette can not realize the design all the time, 1) the polymer battery can not be combined according to the structure of the aluminum shell plastic shell steel shell battery, and the multi-tab is conducted with the cover cap or the cover plate by using laser welding or riveting technology. 2) The heat sealing of the tab glue and the aluminum plastic film of the polymer soft package battery can only be completed by a single tab, and the two overlapped tab glues can leak liquid after being connected in parallel and heat sealed; 3) the cylindrical polymer soft package battery can not adopt the design of a laminated core and a parallel core; 4) the battery market for the electronic cigarette determines the negative tolerance of the battery size design, and no redundant structural space exists inside.
