| titleOfInvention | A kind of preparation method of lithium ion battery anode material nickel cobalt aluminium |
| abstract | The invention discloses a kind of preparation method of lithium ion battery anode material nickel cobalt aluminium, comprises the following steps：Nickel, cobalt and aluminum salt solution are mixed, coprecipitation reaction is carried out again in mixed solution cocurrent addition reactor by precipitating reagent, complexing agent with above-mentioned nickel cobalt aluminium, regulation system pH value is 10 ~ 11, temperature is 40 ~ 60 DEG C, and mixing speed is 500 ~ 1500 revs/min, after 10 ~ 30 h of reaction, filtered, washing, dries, obtains hydroxide precursor；Presoma high temperature pre-sintering is obtained nickel cobalt aluminum oxide, then is mixed with lithium source, high temperature sintering under oxygen atmosphere obtains nickel cobalt aluminium powder after broken and screening.The burn tinctuer pre-sintered by calculating presoma, and with Ni in nickel cobalt aluminum oxide under the different pre-sintering temperatures of XPS analysis 2+ And Ni 3+ Content, obtain Ni 3+ Content highest nickel cobalt aluminum oxide, is converted into Ni with more nickel ions during promoting double sintering 3+ , reduce Li + With Ni 2+ Mixing, improve material chemical property. |
