Description
Technical field
The present invention relates to novel energy resource material technology field, in particularly a kind of selective recovery lithium ion cell anode waste
The method of valuable metal.
Background technology
With extensive use of the lithium ion battery on power vehicle and energy storage material, the yield and demand of lithium ion battery
Amount will constantly increase severely, and from 2005 to 2015, the global annual production of lithium ion battery increased 1200%.And lithium from
Sub- battery is just constantly used in frontier, and its demand can still be increased considerably for 10 years in future.South Korea in 2017, Japan and
The lithium ion battery yield of China will account for more than the 90% of global yield.At present, China has become the maximum of lithium ion battery
One of production, consumption and exported country.
Due to electronic product update speed it is more and more faster, in addition lithium ion battery life-span typically only 1~3
Year, therefore, the waste material produced in the coming years will produce substantial amounts of waste lithium ion and its manufacture cell process.
And containing valuable metals such as nickel, cobalt, manganese, lithium, copper and aluminium in these discarded objects, wherein nickel cobalt manganese is considered as strategy metal,
Occupied an important position in following sustainable material and technology.The supply and demand of the metal needed for current these lithium ion batteries production
Contradiction is increasingly protruded in China.Therefore, if valuable metal that can be in selective recovery waste and old lithium ion battery, not only
It can be avoided to environment and the risk of human health, and the metal for substituting can be provided for each metal industry, reduced to state
The interdependency of outer metals resources, promotes sustainable development and the industrial upgrading of lithium ion battery industry.
Conventional anode material for lithium-ion batteries mainly has cobalt acid lithium, lithium nickelate, LiMn2O4, nickel cobalt manganese three in the market
First positive electrode and LiFePO4 etc..For the recovery of such as Ni, Co, the Mn of valuable metal in positive electrode, study both at home and abroad.
The method being widely used at present be by anode waste active material be added in sulfuric acid, nitric acid, hydrochloric acid and using hydrogen peroxide as
Reducing agent, leaches to the valuable metal in anode waste first;Then the separation of valuable metal is carried out by extraction, or again
Various valuable metals are made to reach the effect being separately recovered by adding various precipitating reagents.So will necessarily result in the increasing of cost recovery
Plus extend with process cycle.
As the A of Chinese invention patent CN 106169624 disclose a kind of lithium ion battery ternary material recovery method, wherein
Propose anode pole piece through peracid is molten, regulation pH, sintering obtains MnO after oxidizerx/ C composite, add ammonium oxalate after
Sintering obtains NiO/Co3O4Mixing material, it is eventually adding NaCO3 and obtains lithium carbonate.This method is divided again by separating valuable metals
Do not reclaim, not only need a large amount of supplementary product onsumptions, and reaction time is more long.
The wet recycle recovery lithium ion cell anode waste being related at present can be separately recovered and utilize valuable metal, again
Lithium salts and other metal ions are obtained, but it is not strong to be primarily due to be separately recovered the selectivity of valuable metal, it is therefore desirable to it is cumbersome
Removal of impurities operation just can guarantee that the purity of product, and this can cause auxiliary material consumption big, and long processing period, processing cost are higher etc.
Shortcoming limits the value of large-batch industrial.And because the specific aim of recovery method is too strong, reclaims product and be only used for weight
It is new to use in the field of synthesizing lithium ion battery, cause current recovery method restricted too big.
