Background technology
As population is continuously increased, resource is constantly exhausted, and people put forward higher requirement to chemical energy source, i.e., high-quality Amount, long-life, low stain, and the lithium rechargeable battery of high-tech, high added value is a wherein spotlight, is caused many big Company is competitively added in the research and development ranks of the product.There is certain longevity as the lithium rechargeable battery of " green energy resource " Life, generally 3 years or so.It is expected that lithium rechargeable battery will become part very important in following solid waste.Such as What deals carefully with them, will be the big problem that people face.
With regard to the method from Call Provision, lithium in failure cobalt acid lithium battery positive electrode, prior art mostly is in acid system Middle addition reducing agent is (such as hydrogen peroxide, Na2SO3) leaching cobalt, lithium.Abroad, the company such as SONY is had been presented for from applying waste lithium ionic two The scheme of cobalt compound is reclaimed in primary cell.Additionally, some researcheres have been also carried out the research of correlation：The employing extraction such as Zhang, The method of precipitation has reclaimed lithium carbonate and cobalt oxalate；And Lee etc. proposes recovery LiCoO2Scheme.Wherein, Contestabile etc. goes back the afflux such as stainless steel casing and aluminum, copper of synthetical recovery spent lithium-ion secondary batteries pole.In state Inside not yet there is company to propose the spent lithium-ion secondary batteries recovery scheme of oneself, the purpose of these recovery schemes is mainly reclaimed Cobalt compound or cobalt metal simple-substance.
《The recovery of waste lithium ion cell anode material lithium cobaltate》It is middle using different recovery schemes to applying waste lithium ionic Secondary cell has carried out reclaiming research：Electrolyte is reclaimed using Allyl carbonate (PC)；Existed using N-Methyl pyrrolidone (NMP) 70 DEG C of stripping active substances；Carbon dust is removed by heat treatment method；Using dissolving with hydrochloric acid cobalt, with Co (OH)2Form is reclaimed, then is weighed New synthesis cobalt acid lithium.The response rate of cobalt is more than 99% in the method, but the handling process process is complicated, and cost recovery is higher.
The content of the invention
From cost recovery during Call Provision in failure cobalt acid lithium battery positive electrode and lithium in order to overcome prior art It is higher, and the technical deficiency of complicated process steps, Call Provision in a kind of cobalt acid lithium battery positive electrode from failure of present invention offer With the method for lithium, sodium bisulfate is mixed with failure cobalt acid lithium battery positive electrode in the method, after compound high-temperature roasting Add water leaching, is filtrated to get the sulfate liquor comprising cobalt element and elemental lithium.The method preparation process is simple, process control By force, it is especially suitable for the recycling of cobalt acid lithium battery cobalt and elemental lithium.
The present invention is achieved through the following technical solutions above-mentioned technical purpose：
A kind of method of Call Provision and lithium in cobalt acid lithium battery positive electrode from failure, it is sour with failure cobalt by sodium bisulfate Anode material of lithium battery mixes, and by the leaching that adds water after compound high-temperature roasting, is filtrated to get the sulfur comprising cobalt element and elemental lithium Acid salt solution.
The method of Call Provision and lithium in the cobalt acid lithium battery positive electrode from failure described above, it specifically includes following steps Suddenly：
(1) sodium bisulfate is mixed homogeneously and obtains compound with failure cobalt acid lithium battery positive electrode, control cobalt element with The mol ratio of element sulphur is 1：3；
(2) roasting 5min～40min obtains baked material under the conditions of compound being placed in into 200 DEG C～600 DEG C；
(3) take out and add water after baked material leaching, extraction temperature is 20 DEG C～90 DEG C, and extraction time is 4-6h；
(4) solid-liquor separation, sulfate liquor of the filtrate as comprising cobalt element and elemental lithium are filtered.
It is above-mentioned from failure cobalt acid lithium battery positive electrode in Call Provision and lithium method in, described step 3) in water with roasting The mass ratio of material is 40-80:1.
The principle of the method is：
4LiCoO2+12NaHSO4==2Li2SO4+6Na2SO4+4CoSO4+6H2O+O2
The present invention has following technical advantage relative to prior art：
The method of Call Provision and lithium uses NaHSO in the cobalt acid lithium battery positive electrode from failure of the present invention4With mistake After effect cobalt acid lithium battery positive electrode is baking mixed, add water leaching；It can obtain the cobalt of higher concentration, lithium leachate, cobalt Leaching rate is more than 95%, the leaching rate of lithium is more than 93%.
