Abstract

The invention belongs to the technical field of lithium ion batteries, and particularly relates to a manufacturing method of a laminated lithium ion battery which comprises a battery box and a battery pack, wherein the battery pack is arranged in the battery box and consists of a plurality of single lithium ion power batteries; a power block and a sliding strip are further included; a sliding groove is formed in one end of the battery box; the power block is connected into the sliding groove in a sliding manner; the power block can slide up and down along the sliding groove; a first spring is arranged in the sliding groove; and one end of the first spring is connected with the bottom wall of the sliding groove. The power block slides up and down along the sliding groove and is matched with the sliding strip to drive a baffle to rotate back and forth between the two groove walls of a ventilation groove, so that heat generated in the working process of the lithium ion power battery is dissipated, and then the wire harness aging speed of the lithium ion power battery is reduced, and the service life of the modular lithium ion power battery is prolonged, and the use effect is 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 MnO2, SOCL2, etc.; it entered practical use in the 1970s; because of its high energy, high battery voltage, large current, and long storage life Long and other advantages, it has been widely used in automobiles and small civilian electrical appliances, such as electric vehicles, mobile phones, portable computers, video cameras, cameras, etc., partially replacing traditional batteries; large-capacity lithium batteries have been tried in electric vehicles and will become 21 It is one of the main power sources of electric vehicles in the century, and will be applied in artificial sat...
