Description
Technical field
The invention belongs to the recovery technique of resource circulation utilization and inorganic material, relate to a kind of recovery and restorative procedure of anode material graphite of waste lithium ion battery.
Background technology
At present, the graphite that is used for lithium ion battery anode material mainly contains two kinds, modified natural graphite and Delanium.The preparation technology of modified natural graphite is generally coarse crushing-attritioning-acid-alkali washing-flotation-oven dry-spheroidization processing-classification-purifying-oven dry-mixing/doping-charing-graphitization-screening, and the technical process of Delanium is material asphalt etc.-thermal polycondensation-extracting-charing-graphitization-screening.No matter be all will be in the modified natural graphite or the preparation process of Delanium through the graphitizing process of temperature more than 2800 ℃, thus the equipment requirements harshness, the energy consumption height.Compare with Delanium, modified natural graphite is at chemical property and all have superiority in price.But graphite resource is limited, and fixed carbon content is 2.34%～34.55% in the graphite deposit ore, average out to about 7.4%; And the graphitic carbon content that reclaims in the waste and old lithium ion battery pole piece is more than 85%, is higher than the grade of graphite ore far away.Resource circulation utilization not only can be saved a large amount of graphite mineral resources, and can reduce energy resource consumption significantly, preserves the ecological environment.
It is reported that the output of global lithium ion battery in 2008 is about 3,000,000,000, and development in recent years is rapid, output increases severely year by year with 20% annual growth rate, and China is the maximum lithium battery producing country in the whole world, accounts for 45% of global total output.Lithium ion battery is running stores, and lithium ion battery average life span 2-3, battery of mobile phone also often discard because of the renewal of mobile phone, and its useful life is shorter.To the end of the year 2011, the lithium ion battery of being produced in 2008 will all lose efficacy, if press battery average quality 40 restrain/, then only the used Li ion cell of China just has 5.4 ten thousand tons.Contain a large amount of graphite and heavy metal cobalt, nickel, manganese in the waste and old lithium ion battery, the electrolyte lithium hexafluoro phosphate, organic solvent etc., unprocessed abandoning, can cause serious and lasting pollution to surrounding environment such as soil, underground water etc., ecological and human health are had bigger potential hazard, belong to dangerous solid waste, must carry out harmless treatment.The recovery industrialization of heavy metal cobalt in the cathode plate of lithium ion battery and nickel, but the recovery of lithium ion battery anode graphite or blank out.
Increase gradually along with the lithium ion battery consumption, the amount of waste and old lithium ion battery also increases year by year, if account for 15% estimation of total cell weight by graphite, to the end of the year 2011, only China's silicon/carbon/graphite in lithium ion batteries weight of scrapping is about 8100 tons, add the graphite waste material and the leftover pieces of large-sized battery enterprise, anode material graphite of waste lithium ion battery will be an inexhaustible huge graphite mine.Therefore, the recovery of anode material graphite of waste lithium ion battery will have good prospect and benefit.
