Abstract
The invention discloses a safe absorbing device for a lithium-ion battery. The safe absorbing device for the lithium-ion battery relates to a lithium battery passive safety concept and is used for solving the problems of fire disasters and other danger due to the fact that the interior of the lithium-ion battery is subjected to high temperature and high pressure. The lithium-ion battery comprises a battery body, wherein the battery body is rectangular or cylindrical, and an electrolyte is contained in the battery body; the battery body is provided with a safety valve; the safe absorbing device is mounted on the battery body; and the safety valve is communicated with safe absorbing device. According to the safe absorbing device for the lithium-ion battery, after the safety valve is opened, high temperature liquid and gas in the battery body can be effectively absorbed, so that the fire disasters and other danger caused by the high temperature liquid and gas are avoided, the problem of potential safety hazards in the wide application of the lithium-ion battery is solved, and thus, the safe absorbing device for the lithium-ion battery has broad market prospects.
Description
Technical field
The present invention relates to field of batteries, refer more particularly to a kind of safe absorption device of lithium ion battery.
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 products; The inside battery primary structure has anode electrode sheet, negative electricity pole piece and barrier film, and barrier film is for the isolation 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 so the internal short-circuit that battery causes in the process of using or when battery internal defect causes outflow or the ejection of high-temperature electrolyte, can burn; Easily 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 at battery, and under the pressure in the battery reached certain situation, safety valve can be opened automatically, internal pressure discharges, thereby avoids blasting; The method such as battery of mobile phone, is feasible to small-sized battery, but for large-scale battery, such as 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 like this breaking out of fire.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point of the prior art and a kind of simple in structure, practical, novel safe absorption device of lithium ion battery that can prevent electrolyte ejection initiation fire, safety is provided.
The present invention realizes in the following way:
A kind of safe absorption device of lithium ion battery includes battery body 1, and described battery body 1 is rectangle or cylindrical, and it contains electrolyte; It is characterized in that: described battery body 1 is provided with safety valve 16; Be equiped with safe absorption device 2 on the described battery body 1; Safety valve 16 is connected with safe absorption device 2.
Described safe absorption device 2 is 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 safe absorption device 2 of the present invention can be made by metal, high-temperature-resistant flame-retardant resin material; Be filled with absorbing material in it, can absorb high temperature flammable liquid and the gas of battery body 1 interior ejection, prevent that it from leaking, initiation fire.
The effect of safety valve 16 of the present invention 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 safe absorption device 2 of the present invention, can effectively absorb high-temp liquid and gas, and make it in the chamber, be in stable state.
In sum, the invention provides a kind of simple in structure, easy to operate, safe, after safety valve is opened, so that the high-temp liquid in the battery body and effective absorption of gas, avoid the fire and other danger that cause thus, for the extensive use of this type of battery has solved the hidden danger of fail safe, have widely market prospects; For lithium ion battery has promoted the passive security performance, and practical safe absorption device.
