Problems solved by technology

[0005] The traditional post-processing of lithium battery cells is generally divided into three steps (formation, aging and molding) or two steps (formation and aging are combined into one step, and molding is one step). This multi-step operation requires more More manpower and longer assembly line work, in the case of a substantial increase in labor costs and a substantial increase in the unit price of rented area, if the traditional method is still used, the manufacturing cost of lithium-ion batteries is bound to be greatly increased; in addition, the existing molding During the process, for the convenience of putting in the battery cell, the battery cell is generally placed flat, and the battery cell is pressed from top to bottom, which sometimes causes the problem that the electrolyte cannot flow back into the battery cell after being squeezed into the air bag. will affect the capacity of the cell

Abstract

A soft-pack lithium battery aging molding method and aging molding device thereof, wherein the device includes a frame, and several heat source plates that can move along the same direction of the frame are arranged on the frame, and on the heat source plate There are several placing parts for placing the electric core, and a pressure applicator, acting on the outermost heat source plate, applying force to the electric core to shape and heat the electric core. The invention has the advantages of accelerating the aging process of the electric core, shortening the aging time of the electric core, improving the aging quality, reducing labor and saving floor space.

Description

technical field [0001] The invention relates to an aging molding method for a soft-pack lithium battery and an aging molding device thereof, in particular to an aging molding method for a soft-pack liquid lithium battery and an aging molding device thereof. Background technique [0002] Due to its many advantages, such as high volumetric energy density and gravimetric energy density, and low self-discharge rate, lithium-ion batteries are widely used commercially in portable appliances, such as mobile phones, laptop computers, and portable camcorders and similar small electronic devices. [0003] In the production process of lithium-ion battery cells, the lithium-ion battery cells need to be formed, aged and shaped before they can be shipped out (some people also refer to the process of forming and aging as the aging process), which forms the traditional lithium-ion battery. The formation process, aging process and molding process in the production process of battery cells a...
