Description
Technical field
The present invention relates to lithium batteries and lithium battery module crushing technology field, more particularly to the broken electrification lithium battery of one kind
With the system of lithium battery module.
Background technology
Lithium battery is answered extensively because its energy density is high, operating voltage is big, memory-less effect and the advantages that have extended cycle life
For in daily life, such as the various electronic products such as video camera, mobile phone, laptop and Portable Measurement Instrument
In and electric vehicle first choice light high-energy power power supply.But after lithium battery is scrapped, environmental and human health impacts band can be usually given
Carry out certain harm, and results in waste of resources；Recycling and innoxious recycling to waste lithium cell is extremely urgent.
With society development and science and technology development, the application of lithium battery is more and more common, especially dynamic lithium battery and
Lithium battery module, as country widelys popularize electric vehicle, future will have a large amount of dynamic lithium batteries and lithium battery module face
Face the problem of scrapping.But according to the statistics of Chinese automobile Technology R ＆ D Center, the rate of recovery of China's waste battery less than 2%,
And contain the valuable metals and graphite, positive electrode etc. such as a large amount of available resources, such as aluminium, copper in waste and old lithium ion battery,
Also contain heavy metal materials and the electrolyte such as nickel, cobalt, manganese, lithium in power battery, once old and useless battery cannot effectively be located
Reason, not only results in the wasting of resources, can also cause seriously to pollute to environment.
When lithium battery especially dynamic lithium battery and lithium battery module are crushed under unprotect, due to having after internal short-circuit
The big energy of the aggregation in space of limit, causes the temperature moment of limited inner space to increase, has reached electrolyte burning point, drawn
Electrolyte is fired, while the inside combustible material of power battery is ignited by electrolyte, causes to catch fire.

It is distributed in positive pole aluminium foil surface, after power battery internal short-circuit, when being warming up to 900 DEG C or so, LiFePO 4 material can occur point
Solution reaction, causes positive electrode to fail.
Ternary material is coated on positive pole aluminium foil surface in ternary battery, after power battery internal short-circuit, is warming up to 300 DEG C
When left and right, ternary material can decompose and discharge partial oxidation, when increasing to over the burning of electrolyte with this temperature, decompose
The oxygen participation of generation is combustion-supporting, interior in a limited space to will produce gas explosion, leads to the component of positive electrode failure and inside battery
Damage or burning.
Method and breaking method before broken when waste and old power battery recycling at present have the following steps：One, first to waste and old electricity
Pond carries out discharge treatment；Two, old and useless battery is cut into separation battery core, shell；Three, pyrolysis processing is carried out before old and useless battery is broken to go
Except substances such as electrolyte, diaphragms；Four, crushing hot treated battery core；Five, raw material separation is carried out to broken material.More than
Method has the disadvantage that：One, it is easy to happen environmental pollution, fire and explosion when old and useless battery is discharged, two, battery core accumulation turns
There is the danger caught fire during moving, while also electrolyte leaks the harm of pollution air；Pyrolysis processing before broken eliminate every
Film increases the discharge capacity of pollutant；Three, precision is difficult to control, easily cause fire, simultaneously when old and useless battery cutting separation
It is only applicable in rectangular cell, is not suitable for other batteries, limitation is strong.
Therefore, in the presence of for the especially dynamic lithium battery of lithium battery in the prior art and lithium battery module shattering process
Disadvantages mentioned above, a kind of system of broken electrification lithium battery and lithium battery module is provided, present technical problem urgently to be resolved hurrily is become.
