Abstract
The invention provides a method for performing the batch repair of a waste lithium ion battery of a mobile telephone. The method comprises the following steps: a recovered waste lithium ion battery is discharged to 2.75V firstly, and a battery capacitance division cabinet can be used for discharging; the lithium ion battery after being discharged is charged by using homemade direct current pulsant activation equipment; charged activation is performed for 10-15 minutes, then the lithium ion battery is laid up for 30 minutes; and the capacitance division cabinet is used for testing the capacitance of the lithium ion battery, and the capacitance of part of batteries can reach the nominal capacity of the batteries. The method has the advantages of simple manufacture, easy operation, circulation utilization of waste battery, source waste reduction and environment protection.
Description
Technical field:
The present invention relates to a kind of technology that old and useless battery is carried out the batch reparation, relate in particular to mobile phone is carried out the method for reparation in batches with waste and old lithium ion battery
Background technology:
Along with the development of electronic product, mobile phone has become an indispensable part in people's daily life, and lithium ion battery is also increasing as its use amount of power of mobile phone.Because the renewal and the improper use of mobile phone model have produced a large amount of disused mobile batteries.Owing to there is not unified processing method, the lithium ion battery major part of scrapping is at present abandoned everywhere, not only causes severe contamination to environment, has also wasted ample resources.
In this case, the experimental work that has many research institutions to be correlated with is both at home and abroad handled disused mobile battery, and purpose is to recycle wherein useful metallic elements.Sony corporation of Japan is advanced correlative study with mine company of Sumitomo Metal Industries.But they extract relevant useful element by waste and old lithium ion battery is thoroughly destroyed, and course of work complexity is easy to cause secondary pollution.
Based on this, the inventor has proposed a kind of new thinking, can find a kind of method that waste mobile phone is effectively repaired with lithium ion battery, can allow its state of resuming work again and need not carry out destructive recycling.Through experiment repeatedly, the inventor has found a kind of technology that can carry out the batch reparation to waste and old lithium ion battery.Use present technique not only can make resource reutilization, but also can reduce environmental pollution, play the effect of environmental protection and energy saving.
Summary of the invention:
The objective of the invention is to make mobile phone to reach the purpose of cycling and reutilization with waste and old lithium ion battery.The method is simple to operate, and cost is low, can also play the effect of environmental protection and energy saving.
The present invention is realized by following technical proposals: the present invention is that a kind of handle is scrapped lithium ion battery, activates the lithium ion passivation layer through Rectified alternating current and reaches the method that circulates in utilization, and its feature may further comprise the steps:
(1) battery discharge
Waste mobile phone is discharged to 2.75V with lithium ion battery with the partial volume cabinet
(2) charging activates
Under the normal temperature, with the lithium ion battery after the discharge, with the activation of charging of homemade 12V dc pulse activated equipment.Charging activates about 10 minutes, shelves then 30 minutes
(2) capacity sorting
With the lithium ion battery after the charging activation, test its capacity with the partial volume cabinet, the lithium battery that the capacity of sub-electing closes behind to be tested the finishing is in order to recycling.
The invention has the advantages that operating process is simple, cost is low, and the lithium ion reparation circulates in utilance and reaches more than 80%.
Specific embodiments:
Below more specifically introduce implementation method of the present invention with non-limited way
Embodiment 1
Get 10000 mobile phone waste and old lithium ion batteries, after discharging into 2.75V with the partial volume cabinet, it is charged with homemade 12V dc pulse activated equipment activate 10 minutes, after shelving 30 minutes then, testing its capacity with the partial volume cabinet, test result finds have 8230 mobile phone capacity of lithium ion battery to reach nominal capacity, this shows to use the reparation of this technology to scrap lithium ion battery, repairs success rate and reaches 82.3%
Embodiment 2
Get 10000 useless mobile phone waste and old lithium ion batteries, after discharging into 2.75V with the partial volume cabinet, it is charged with homemade 12V dc pulse activated equipment activate 13 minutes, after shelving 30 minutes then, testing its capacity with the partial volume cabinet, test result finds have 9008 mobile phone capacity of lithium ion battery to reach nominal capacity, this shows to use the reparation of this technology to scrap lithium ion battery, repairs success rate and reaches 90.8%.
Claims (1)
1. one kind the mobile phone waste and old lithium ion battery, activates the method that the lithium ion passivation layer reaches cycling and reutilization through Rectified alternating current.Its feature may further comprise the steps:
(1) discharge of battery
To scrap lithium ion battery and be discharged to 2.75V with the partial volume cabinet
(2) charging activates
To scrap lithium ion battery after the discharge, with the activation of charging of homemade 12V dc pulse activated equipment.Charging was shelved 30 minutes after activating 10-15 minute
(3) capacity sorting
Lithium ion battery with after the charging activation carries out volume test with the partial volume cabinet, the lithium ion battery that the capacity of selecting is qualified.
