Problems solved by technology

The safety box can play the role of explosion-proof and flame-retardant for lithium-ion batteries, but when storing charged lithium batteries, because the lithium batteries themselves have the ability to undergo redox reactions, when the battery has an internal short circuit, the internal temperature of the cabinet will be very high , when the temperature exceeds the temperature limit of the metal cabinet itself, the cabinet will collapse, and when the battery in the safety box burns and explodes, the fire cannot be controlled in the safety box

[0021] Step 1: Make a double-layer steel cabinet

[0022] (1) Weld 5 pieces of cold-rolled steel plates 1 of 100mm×100mm×1.5mm into the inner wall, and weld 5 pieces of cold-rolled steel plates 2 of 140mm×140mm×1.5mm into the outer wall; each inner surface of the outer wall is vertically welded with the same length and size Angle steel 7, and paste the perlite plate as heat insulating board 3 on the inner surface of outer wall, the length of angle steel is the size that can weld the inner surface of outer wall and the inner wall outer surface of double-layer steel plate with outer wall;

[0023] (2) The opening of the inner wall is centered in the same direction as the opening of the outer wall, and the inner wall is put into the outer wall; the angle steel welded around the outer wall is welded together with the corresponding outer surface of the inner wall; concrete slurry is poured between the outer surface of the inner wall and the insulation board ;

[0024] (3) After th...

Abstract

The invention relates to a safety storage cabinet for a lithium battery. The safety storage cabinet comprises a cabinet body and a cabinet cover which are fixedly arranged into a whole through a lock catch. The safety storage cabinet is characterized in that the cabinet body and the cabinet cover are hollow double-layer steel plates, wherein the hollow parts are filled with insulating plates and concrete slurry; a temperature sensor is fixedly mounted on the bottom of the cabinet cover, an alarm is fixedly mounted on the top of the cabinet cover, and the temperature sensor and the alarm are integrally connected through circuit. The insulating materials between the double layers of steel plates delay the time of conducting the high temperature inside the cabinet body to the outer part of the cabinet body; the concrete slurry between the double layers of the steel plates guarantees that that cabinet body framework is not collapsed under conditions of combustion, explosion and the like of the battery, so that the combustion and the explosion are not spread out of the cabinet body, and the safety of a lithium battery storage environment is guaranteed; the temperature sensor on the cabinet cover and the alarm connected with the temperature sensor can inform people of potential safety hazards of the lithium battery in the storage cabinet to take protective measures in advance.

Description

technical field [0001] The invention belongs to the technical field of storage cabinets for dangerous goods, in particular to a safety storage cabinet for lithium batteries. Background technique [0002] In recent years, with the increasing application of lithium batteries, examples of safety accidents occurring in lithium batteries during transportation, storage, sales, etc. are not uncommon. [0003] At present, the lithium battery has accumulated a huge amount of energy when it is in the charging state. Once the ambient temperature of the lithium battery is not controlled properly, the lithium battery is very prone to accidents such as explosion and fire. If proper measures are not taken, when an accident occurs to one battery, it will spread to other adjacent batteries, causing the fire to spread, and then lead to a bigger accident. [0004] After searching, it is found that the application number is 201120323564.0, the publication number is CN202282390U, and the name i...
