Description
Technical field
The utility model belongs to a kind of rapid failure device for scrapping lithium battery.
Background technique
Lithium ion battery refers to the general name with lithium ion inlaid scheme for positive material cell.The charge and discharge of lithium ion battery
Electric process is exactly the insertion and deintercalation process of lithium ion.During the insertion of lithium ion and deintercalation, simultaneous and lithium from
The insertion and deintercalation of sub- equivalent electronics.When lithium battery charges, lithium atom is ionized into lithium ion and electronics in anode, and lithium from
Son moves and electronic synthesis lithium atom to cathode.When electric discharge, lithium atom negative terminal surface out of graphite crystal be ionized into lithium ion and
Electronics, and lithium atom is synthesized at anode.
Lithium battery with access times increase and maximum capacity is gradually reduced, needed when dropping to a certain degree to lithium electricity
Pond carries out scrapping processing.The reason of lithium battery maximum capacity declines mainly has：
(1) in terms of electrode, repeated charge reduces electrode activity surface area, and current density improves, and polarization increases；It is living
The structure of property material changes；The electrical contact of active particle is deteriorated, or even falls off；Electrode material (including collector) corrosion.
(2) in terms of electrolyte solution, electrolyte or conductive salt decomposition cause its conductivity to decline, and decomposition product causes interface
Passivation.With the increase of battery charging and discharging number.Since electrode material oxidation corrosion can consume a part of electrolyte, lead to electricity
It solves liquid to lack, pole piece completely clear and rich cannot be set so that electrochemical reaction is incomplete so that battery capacity is not achieved to electrolyte
Meter requires.
(3) diaphragm obstruction or damage, internal short-circuit of battery etc..
Lithium battery is when scrapping processing, it usually needs through overdischarge, removing shell, electrode material dissolution, metal recovery etc.
Step.But lithium battery both just after discharge, also tends to certain residual voltage, cannot accomplish no-voltage completely, be deposited in
It is easy to happen short circuit when handling together, causes the serious consequences such as on fire, explosion.There is pollution ring in conventionally employed bubble salt water mode
Border handles the problems such as time is long, failure effect is inconsistent.
Utility model content
Place in view of the shortcomings of the prior art, the technical problem to be solved by the utility model is to provide a kind of reports
The device of useless lithium battery rapid failure, it can make lithium battery interior micro-short circuit to the device, to thoroughly eliminate the residual of lithium battery
Remaining voltage.
Technical solution provided by the utility model is：
One kind scraps lithium battery rapid failure device, and the rapid failure device includes arresting element, power supply and switch,
Lithium battery and arresting element, power supply, switch constitute series circuit, and the cathode of lithium battery is electrically connected with the anode of power supply, lithium battery
Anode be electrically connected with the cathode of power supply.
For lithium ion battery, usually used plus plate current-collecting body is aluminium foil, and negative current collector is copper foil.This is practical
It is novel to make full use of this characteristic, will close the switch, lithium battery is connected with power supply, arresting element, due to lithium battery cathode with
The anode electrical connection of power supply, the anode of lithium battery are electrically connected with the cathode of power supply, are equivalent to power supply to lithium battery reverse charging.This
When, copper foil can occur to react as follows：
Cu→Cu++e-
Generated Cu+In power source charges copper branch can be formed in negative terminal surface by crystallization deposition in the form of metallic copper
Crystalline substance, copper dendrite, which can penetrate diaphragm, makes lithium battery internal short-circuit, so that lithium battery thoroughly fails, facilitates and subsequent scraps processing.
The arresting element is usually resistance or electrolyte or load.Preferably, the arresting element is electric discharge electricity
Resistance.
Using technical solution provided by the utility model, compared with prior art, there is such as beneficial effect：
Scrapping lithium battery rapid failure device and can making to scrap lithium battery internal short-circuit for the utility model, eliminates remaining electricity
Pressure, so that lithium battery is thoroughly failed, facilitate it is subsequent scrap processing, will not cause it is on fire, explode etc. accidents.
Detailed description of the invention
Fig. 1 is the circuit diagram that the utility model scraps lithium battery rapid failure device.
Specific embodiment
Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described
Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model
Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The range of the utility model protection.
Referring to Fig.1, one kind scrapping lithium battery rapid failure device, including arresting element R1, power supply P1 and switch K1, lithium electricity
Pond and arresting element R1, power supply P1, switch K1 constitute series circuit, and the cathode of lithium battery B1 is electrically connected with the positive P1 of power supply,
The anode of lithium battery B1 is electrically connected with the cathode of power supply P1.The arresting element R1 is discharge resistance.
The working principle of the utility model is：Switch K1 is closed, lithium battery B1 connects with arresting element R1, power supply P1,
Since the cathode of lithium battery B1 is electrically connected with the anode of power supply P1, the anode of lithium battery B1 is electrically connected with the cathode of power supply P1, phase
When in power supply P1 to lithium battery B1 reverse charging.At this point, copper foil can occur to react as follows：
Cu caused by Cu → Cu++e- (I)
Copper dendrite can be formed in negative terminal surface by crystallization deposition in the form of metallic copper in charging, copper dendrite can be worn
Saturating diaphragm makes lithium battery internal short-circuit, so that lithium battery thoroughly fails, facilitates and subsequent scraps processing.After lithium battery failure, it will open
It closes K1 to disconnect, that is, completes the crash handling of lithium battery.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases
The technical field of pass, is also included in the patent protection scope of the utility model.
