Abstract
This invention relates to a method for covering alkyl Co2O on the surface of Ni(OH)2 including: 1, stocking: preparing Co2SO4: 0.5-2mol/L, NaOH solution:3-8mol/L, ammonia:6-10mol/L, 2, adding one portion of ball Ni(OH)2 in a reaction kettle with 6-12 portions of deionized water in it already to be mixed and control the temperature at 30-70deg.C, then adding 1 of Co2SO4 solution, 2-2.5 of NaOH solution and 0.8-1.5 ammonia in a reaction kettle to be reacted for 3-8 hours with the PH value at 10-11, then stopping feeding in the Co2SO4 solution and adding NaOH solution so that the PH value rises to 12-13.6, then adding chloros in 1-5% weight of Ni(OH)2 after the temperature rises to 80-90deg.C to be mixed for 30-60 minutes, 3, carrying out separation of the solid and liquid to be dried.
Description
Technical field
The present invention relates to be used for direct transformationization chemical energy is the device of electric energy, particularly a kind of method at the ball shape nickel hydroxide surface cladding hydroxy cobalt oxide.
Background technology
Ball-shape nickel hydroxide is the positive active material of alkaline nickel-hydrogen battery, because nickel hydroxide itself is a kind of semiconductor, must add certain conductive agent when making pole plate, or coat one deck cobalt compound on the surface, could improve anodal electric conductivity greatly.At present, the method that coats the hydroxyl hydrogen cobalt oxide at ball shape nickel hydroxide surface is to coat one deck hydroxide cobalt on the surface at ball-shape nickel hydroxide earlier, and washing and drying reoxidizes then.Its shortcoming is that oxidation is all inhomogeneous, and operation is more complicated also.
Summary of the invention
The purpose of this invention is to provide a kind of coat and oxide layer is even, the method at the ball shape nickel hydroxide surface cladding hydroxy cobalt oxide of simple and reliable process.
Technical scheme of the present invention is finished as follows, a kind of method at the ball shape nickel hydroxide surface cladding hydroxy cobalt oxide, it includes following technological process: first gets the raw materials ready, compound concentration is the cobalt sulfate solution of 0.5-2 mol, concentration is the sodium hydroxide solution of 3-8 mol, concentration is the ammoniacal liquor of 6-10 mol, also have ball-shape nickel hydroxide and deionized water, and clorox is standby, second, by weight 1 part of adding of ball-shape nickel hydroxide is formerly added in the reactor that deionized water 6-12 part is arranged, the control temperature in the kettle is 30-70 ℃ in stirring, then with measuring pump with three kinds of above-mentioned solution cobalt sulfate solution 1 in molar ratio, sodium hydroxide solution 2-2.5, the ratio of ammoniacal liquor 0.8-1.5, add in the reactor and react, the maintenance pH value is 10-11, reaction time is 3-8 hour, stop the cobalt sulfate solution charging, continue to add sodium hydroxide solution, make pH value rise to 12-13.6, temperature is elevated to the clorox that adds ball-shape nickel hydroxide weight 1-5% after 80-90 ℃ again, stirred 30-60 minute, the 3rd step was that the solution that reaction is finished is carried out Separation of Solid and Liquid, the solid product washing back of separating is under 100-120 ℃ of condition, and oven dry promptly obtained the product of ball shape nickel hydroxide surface cladding hydroxy cobalt oxide in 2-3 hour.
The electrode material that the present invention produces has and coats and oxide layer is even, technology is simple, electric conductivity is strong advantage, deposits 1-3 and still have capacity restorability more than 98% after making battery, than conventional ball-shape nickel hydroxide raising 15-30%.
Embodiment
Embodiment one:
Taking by weighing 8 kilo sulfuric acid cobalts dissolves in 8 kilograms the deionized water, be made into cobalt sulfate solution, compound concentration is that the sodium hydroxide solution and the concentration of 4 mol are the ammoniacal liquor of 8 mol again, and adding in capacity is 1000 liters reactor and adding apparent density again behind 500 kilograms of deionized waters is 1.72 gram/cm
350 kilograms of ball-shape nickel hydroxides, under agitation add in the reactor respectively three kinds of solution simultaneously with measuring pump, keeping the flow of cobalt sulfate solution is 5 liters/hour, and the flow of adjusting sodium hydroxide solution and ammoniacal liquor is 10.5 ± 0.05 in order to the control pH value, and temperature is controlled at 55 ± 2 ℃.Charging finishes as cobalt sulfate solution, continuing to add sodium hydroxide solution makes pH value bring up to 12.5, temperature is elevated to 85 ± 1 ℃, add 1 kilogram of clorox again, continued stirring reaction 30 minutes, Separation of Solid and Liquid, washing then promptly obtained the ball-shape nickel hydroxide that the surface coats one deck hydroxy cobalt oxide in 3 hours with drying plant drying under 105 ℃ of conditions.Take by weighing the sample making Ni-MH battery, after testing, it is 278mAh/g that this sample 0.2C discharges and recharges gram volume, and capacity restorability is 99%.
