Technical field
The present invention relates to nickel LiMn2O4 preparation technology, relate in particular to a kind of technique of preparing nickel LiMn2O4 taking waste lithium cell as raw material reverse reclamation.
Background technology
Along with the development of digital product industry, people increase day by day to the demand of battery. Nickel LiMn2O4 is a kind of important anode material of lithium battery, produces and uses increasingly extensively, and market demand is larger. When lithium battery is flourish, can predict, in the near future, after battery stops, can enter the stage of scrapping, can calculate that with the quantity of current lithium battery its learies is also huge on an equal basis.
Waste lithium cell positive electrode is nickel LiMn2O4 etc., can reclaim and be utilized, and makes metal powder, metal oxide, chemical industry salt etc. But best mode still reclaims nickel LiMn2O4 by reverse reclamation technique, is prepared into battery material, realizes recycling.
At present, reclaiming the technique of nickel lithium manganate battery material, is generally in the purification of metals liquid of battery material, to add precipitating reagent to make nickel manganese precipitated metal out, is then prepared into nickel manganese presoma through high-temperature calcination, then mixes lithium source and prepare nickel LiMn2O4. The precipitating reagent using can be solids of sedimentation agent, as carbonate; Also can be liquid precipitation agent, as ammoniacal liquor. But the cost compare that feeds intake is high, if ammoniacal liquor is made precipitating reagent, can produce ammonia nitrogen waste water, neither environmental protection, also increases cost for wastewater treatment.
Electrodeposition process is a kind of current method that reclaims metal simple-substance, still, because the deposition potential of nickel, manganese element is larger, easily separates out separately nickel oxide and manganese oxide when electro-deposition apart, and more difficult generation codeposition obtains Ni, Mn oxide; And in reaction system, ratio and the total concentration of nickel, manganese ion concentration is larger on the appearance structure impact of Ni, Mn oxide, therefore not it was reported that at present best nickel, the manganese ion concentration of bright electric deposition nickel Mn oxide.
