Safety device for formation and sub-capacity of lithium ion battery

Abstract

A safety device for lithium-ion batteries, including a cabinet body; at least one row of battery compartments are arranged in the cabinet body, the upper end of the battery compartment is open, and the battery compartment is composed of an insulating fireproof layer on the inner layer and a stainless steel layer on the outer layer ; The battery compartments are connected in series through shafts to form a battery compartment row. The two ends of the battery compartment row are respectively provided with rotating shafts, and both ends of the rotating shaft pass through the side wall of the cabinet body; Battery positioning mechanism. The present invention uses a battery compartment with a two-layer structure so that the battery has a good insulation effect from the outside world, and avoids short-circuiting of the battery due to careless operation by personnel or other accidents. The battery compartment with a two-layer structure also has a high explosion-proof capability; by using the structure of the battery compartment's rotating shaft, the battery can be turned over at multiple angles during the static stage (to improve the effect of electrolyte infiltration), avoiding the need for manual handling of the batteries one by one. Flip, the workshop production efficiency 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...
