The invention belongs to the technical field of lithium electronic batteries, and in particular relates to a manufacturing method of a laminated lithium ion battery. The laminated lithium ion battery includes a battery box and a battery pack; the battery pack is installed in the battery box, and the battery pack It is composed of a plurality of single lithium-ion power batteries; it also includes a power block and a slide bar; a chute is provided inside one end of the battery box; the power block is slidably connected in the chute; the power block can slide along the The groove slides up and down; the No. 1 spring is provided in the chute; one end of the No. 1 spring is connected to the bottom wall of the chute; the present invention slides up and down along the chute through the power block and the slide bar drives the baffle plate in the ventilation groove. The back-and-forth rotation between the two groove walls makes the heat generated by the lithium-ion power battery dissipate during the working process, thereby slowing down the aging speed of the wiring harness of the lithium-ion power battery, and making the service life and use effect of the modular lithium-ion power battery get improved.
Description
technical field [0001] The invention belongs to the technical field of lithium-ion batteries, and in particular relates to a manufacturing method of laminated lithium-ion batteries. Background technique [0002] Lithium power battery is a new type of high-energy battery successfully developed in the 20th century; the negative electrode of this battery is metal lithium, and the positive electrode is MnO 2 , SOCL 2 etc.; entered into practical use in the 1970s; because of its advantages of high energy, high battery voltage, large current, and long storage life, it has been widely used in automobiles and small civilian electrical appliances, such as electric vehicles, mobile phones, portable computers, cameras, Cameras, etc., have partially replaced traditional batteries; large-capacity lithium batteries have been tried in electric vehicles, and will become one of the main power sources for electric vehicles in the 21st century, and will be used in artificial satellites, aeros...
