Novel square lithium battery standardized module encapsulation case and PACK method

Abstract

The invention discloses a novel square lithium battery standardized module encapsulation case and a PACK method. The novel square lithium battery standardized module encapsulation case comprises an upper box, a lower box, a box cover and an electrode substrate, wherein the centers of the front end and the rear end of the outer side of the box cover are inward punched to form a mounting groove, a mounting boss is formed on the front end and the rear end of the inner side of the box cover, a strip-shaped clamp slot is formed in the outer side end of the mounting groove, the electrode substrate is fixedly connected with the mounting boss, a first card is arranged at the center of one side of the electrode substrate, and is vertically folded to form a second card, and the second card is foldedto form a third card; the electrode substrate is arranged inside the box cover; the upper box and the lower box are mutually clamped to form a standardized battery pack unit; and a plurality of standardized battery pack units are sequentially spiced. Through the mutually embedded structure design and automatic mutual embedded limitation, a large battery pack is facilitated to be efficiently and rapidly assembled, all welding technologies can be avoided, the battery packing cost can be effectively lowered, and the disassembling and maintenance are also convenient; the heat dissipation effect is obvious, meanwhile the weight is lightened, and the weight energy density of the battery module is beneficially improved.

Description

technical field [0001] The invention belongs to the field of battery packaging, and in particular relates to a novel square lithium battery standardized module packaging shell and a PACK method. Background technique [0002] With the advancement of science and technology and the enhancement of human environmental protection awareness, the green energy industry at home and abroad has entered a stage of rapid development. Carbon is used for negative electrodes, lithium transition metal composite oxides are used for positive electrodes, and carbonate mixtures are used. Large-capacity lithium-ion batteries based on electrolytes have begun to be widely used. [0003] Traditional secondary batteries (lead-acid batteries, nickel-cadmium batteries, etc.) have been unable to meet many of today's new technologies due to serious defects such as high pollution (production process and materials), toxicity (lead, cadmium), low energy density, and low voltage platform. The development nee...

Problems solved by technology

Aluminum shell / steel shell battery cells have the advantages of high strength, good compression resistance, high safety, and easy external assembly; although flexible packaging lithium battery cells have strong shape plasticity and high volumetric energy density, the monomer packaging technology has yet to be developed. Improvement, in the prior art, the power supply formed by the flexible package lithium battery monomer has poor heat dissipation, complex structure and difficult assembly, and can not protect the battery safely, and the service life is short
