Abstract
The utility model discloses a safe absorption device of a lithium ion battery, which has a lithium ion battery passive safety concept and solves the problem of causing fire disasters and other dangers caused by high temperature and high pressure in the lithium ion battery. The device comprises a battery body, wherein the battery body is rectangular or cylindrical and contains electrolyte; the battery body is provided with a safety valve; the battery body is provided with the safe absorption device; and the safety valve is communicated with the safe absorption device. After the safety valve provided by the utility model is opened, high-temperature liquid and gas in the battery body can be effectively absorbed, thereby avoiding the fire disasters and other dangers and solving hidden dangers of the safety by widely applying the battery; and therefore, the market prospect of the safe absorption device of the lithium ion battery is wide.
Description
Technical field
The utility model relates to field of batteries, refers more particularly to a kind of lithium ion battery safety absorption plant.
Background technology
Excellent performance has extended cycle life, and has the lithium ion battery of high-energy-density, has been widely used at present on mobile communication and the digital series products; The inside battery primary structure has positive electrical pole piece, negative electricity pole piece and barrier film, and barrier film is to be used to isolate positive, negative electrode plate; Current battery might overcharge in the process of charge or discharge, overcurrent and cause battery temperature rising pressure to strengthen, so that blast; Electrolyte in the battery is flammable liquid, can cause burning in temperature during greater than its burning-point; If, can burn so the internal short-circuit that battery causes in the process of using or when battery internal defect causes the outflow or the ejection of high-temperature electrolyte; Be prone to cause security incident.
At present in order to prevent that battery electrolyte in the battery in the process of charge or discharge from high temperature blasting; It is provided with safety valve on battery, under the pressure in the battery reached certain situation, safety valve can be opened automatically; Internal pressure discharges, thereby avoids blasting; The method like battery of mobile phone, is feasible to small-sized battery, but for large-scale battery, and like automobile batteries etc., the electrolyte of a large amount of high temperature sprays from body after safety valve is opened, and electrolyte is flammable body, so be easy to breaking out of fire like this.
The utility model content
The purpose of the utility model is to overcome above-mentioned weak point of the prior art and a kind of simple in structure, practical, novel lithium ion battery safety absorption plant that can prevent electrolyte ejection initiation fire, safety is provided.
The utility model is realized through following mode:
A kind of lithium ion battery safety absorption plant includes battery body 1, and described battery body 1 is a rectangle or cylindrical, and it contains electrolyte; It is characterized in that: said battery body 1 is provided with safety valve 16; Be equiped with safe absorption plant 2 on the said battery body 1; Safety valve 16 is connected with safe absorption plant 2.
Described safe absorption plant 2 is a cavity, is filled with absorbing material in it.
Described absorbing material can be solid-state material, powder attitude material, liquid material, colloidal materials, polymeric foam.
The cavity that the utility model safety absorption plant 2 can be processed by metal, heat-resistant fireproof resin material; Be filled with absorbing material in it, can absorb the high temperature flammable liquid and the gas of ejection in the battery body 1, prevent that it from leaking, initiation fire.
The effect of the safety valve 16 of the utility model is: when lithium battery interior pressure is worth more than or equal to unlatching, safety valve 16 can be opened automatically, and when lithium battery interior pressure is worth less than unlatching, safety valve 16 can be in closed condition.
Be filled with absorbing material in the utility model safety absorption plant 2, can effectively absorb high-temp liquid and gas, and make it in the chamber, be in stable state.
The utility model safety absorption plant 2 can load and unload.
In sum; The utility model provide a kind of simple in structure, easy to operate, safe, after safety valve is opened; Make high-temp liquid and effective absorption of gas in the battery body; Avoid the fire and other danger that cause thus,, have extensive market prospects for the extensive use of this type of battery has solved the hidden danger of fail safe; For lithium ion battery has promoted the passive security performance, and practical safe absorption plant.

Described safe absorption plant 2 is a cavity, is filled with absorbing material in it.
Described absorbing material can be solid-state material, powder attitude material, liquid material, colloidal materials, polymeric foam.
The cavity that the utility model safety absorption plant 2 can be processed by metal, heat-resistant fireproof resin material; Be filled with absorbing material in it, can absorb the high temperature flammable liquid and the gas of ejection in the battery body 1, prevent that its place from letting out initiation fire.
The effect of the safety valve 16 of the utility model is: when lithium battery interior pressure is worth more than or equal to unlatching, safety valve 16 can be opened automatically, and when lithium battery interior pressure is worth less than unlatching, safety valve 16 can be in closed condition.
Be filled with absorbing material in the utility model safety absorption plant 2, can effectively absorb high-temp liquid and gas, and make it in the chamber, be in stable state.
The utility model safety absorption plant 2 can load and unload.
As shown in Figure 2; The utility model can form a large-scale battery body by several battery body 1 serial or parallel connections; Be equiped with the safe absorption plant 2 of combination on the large-scale battery body,, and can not influence other battery bodies 1 when the leakage of certain battery body 1 generation electrolyte.
The preferential embodiment of the utility model: as shown in Figure 1, safety valve 16 is convexly set on the battery body 1; Be convenient to be connected with safe absorption plant 2; Safety valve 16 is provided with sealing ring with the junction of safe absorption plant 2; Absorbing material in the safe absorption plant 2 is filled in its inwall, the middle cavity 22 that forms; Be located at the absorbing material of safety valve 16 junctions and form taper 21, be convenient to electrolyte and high-temp liquid and gas centralized collection in the battery body 1; The cavity 22 that absorbing material forms is convenient to the buffering of electrolyte and high-temp liquid and gas pressure, thereby the electrolyte of feasible ejection and high-temp liquid and gas are convenient to the absorption of absorbing material.
