Abstract

The invention discloses a safety device for formation and sub-capacity of a lithium ion battery. The safety device comprises a cabinet, wherein at least a row of battery compartments are arranged in the cabinet; an opening is formed at the upper end of each battery compartment; each battery compartment consists of an internal insulation fireproof layer and an external stainless steel layer; the battery compartments are connected in series by shafts so as to form a battery compartment row; rotating shafts are arranged at two ends of the battery compartment row; the two ends of each rotating shaft penetrate through the side wall of the cabinet; and a battery locating mechanism for locating the battery is arranged at the upper end of each battery compartment. Due to the adoption of the battery compartments of a two-layer structure, the battery has good insulation effect on the outside; and the short circuit of the battery caused by inappropriate operation of an operator or other accidents is avoided. The battery compartments of the two-layer structure further have high anti-explosion capability; and due to the adoption of the rotating shafts of the battery compartments, the battery can rotate in multiple angles in a standing stage (which can improve the infiltration effect of electrolyte); and the battery does not need to be manually rotated one by one. Therefore, the production efficiency of a workshop is greatly improved.

Description

technical field [0001] The invention relates to a safety device for lithium-ion batteries when they are divided into volumes. Background technique [0002] As a new generation of secondary batteries, lithium-ion batteries have become widely used power products due to their advantages such as high single voltage, high energy and power density, long life, light weight, no memory effect, and no pollution. Its application fields mainly include various portable electronic consumer goods (such as smart phones, tablet computers, digital cameras, etc.); supporting energy storage for solar / wind power plants; pure electric vehicles (EV) and hybrid electric vehicles (HEV); military weapons and equipment; aerospace fields etc. The production and manufacture of lithium-ion batteries is a complex process involving multiple steps: from the initial slurry mixing to coating, rolling, die-cutting, lamination assembly, liquid injection, chemical composition, etc. The process precision contro...
