Description
Technical field
The present invention relates to technical field of nickel, and in particular to a kind of used under low temperature the secondary cell of resistance to floating charge and its
Preparation method.
Background technology
With electronic product miniature portable development trend, rechargeable battery application is more and more extensive.Nickel-hydrogen chargeable cell with
Its specific energy is high, memory-less effect, it is light and handy, portable the advantages of enjoy people to favor.Charged on Ni-MH battery on the market at present
Mode is often charged with small constant current, and the method is convenient and simple, low cost, but without charge cutoff condition, it is big to battery injury, because
This is higher to the resistance to floating charge requirement of battery.Due to the limitation of some specific occasions, such as in cold snap, Ni-MH battery need to be in low temperature
Lower normal work, but general Ni-MH battery is difficult releasing electricity, and high-rate performance is then worse.
Ni-MH battery capacity of the prior art occurs declining the very fast phenomenon that can not put electricity even with the reduction of temperature,
Main cause is that the capacity of (1) positive electrode electric conductivity and poor (2) negative material of stability is very fast as the reduction of temperature declines,
Negative conductive and compound oxygen ability during overcharge, negative pole reserved capacity is low during electric discharge.Therefore both positive and negative polarity electric conductivity is improved
And negative pole reserved capacity can be particularly important for low temperature overcharge resistance performance.
At present, the method for commonly using raising positive conductive and stability is that the change of cobalt is added in conventional ball type nickel hydroxide
Compound, so as to active material surface forms conductive network in discharge and recharge, is easy to the transmission of proton and electronics, improves leading for electrode
Electrically.The conventional cobalt and compound for doing the addition of nickel positive pole has metal Co powder, CoO, β-CoOOH (oxidation state is 2.5-2.93) etc.,
It is generally acknowledged that bivalent Co is not conductive in itself, CoOOH is electrochemically oxidized into when in initial charge and just had
It is conductive, so as to form conductive network with active material.The common method for improving negative material reserved capacity is negative pole alloy
Hydrogenization method storage hydrogen when powder is manufactured, volumetric expansion when the method is using absorption hydrogen, volume contraction when putting hydrogen produces alloy
Numerous cracks and new dough, promote further absorption, expansion, the fragmentation of hydrogen, untill hydrogen saturation.To need to be closed during due to hydrogenation
Gold bullion is put into autoclave, is passed through high-purity hydrogen, therefore, the method need to use high pressure resistant equipment, and hydrogen discharge is easy when unclean
Heating, production is dangerous high, and efficiency is low, and inhales to put Hydrogen Energy power and significantly decline even to lose under low temperature overcharge conditions and put Hydrogen Energy
Power, therefore application in Ni-MH battery low temperature discharge field is restricted.

Compared with prior art, the invention has the advantages that：
The present invention adds CoO and γ-CoOOH in nickel positive pole, effectively improves negative pole priming volume and positive conductive and steady
It is qualitative, so as to improve low temperature overcharge resistance performance energy.The oxidizing potential of CoO is than Ni (OH)2Oxidizing potential it is low, when nickel electrode charge
When, cause at Ni (OH)2Just the CoOOH of stabilization is formd before being converted into NiOOH, when being charged during positive and negative electrodes in same, negative pole can be pre-
Portion capacity has been filled, capacity of negative plates, such as Fig. 1 has been improve.And γ-CoOOH oxidation state is 3-4, conductance (10-2Ω-1S-1) than β-
CoOOH 3 orders of magnitude (10 high-5Ω-1S-1), i.e., 1000 times, therefore add the nickel positive conductive of high conductivity γ-CoOOH
More preferably；Therefore γ-CoOOH improve the electric conductivity of positive pole, reduce the oxidizing potential of nickel electrode, improve the precipitation of oxygen in nickel electrode
Overpotential, when generation is overcharged, to preventing electrode expansion from playing certain inhibitory action, so that improving low temperature overcharges stability.
When the cell is discharged, the easy region of discharge of negative pole point and difficult region of discharge, such as improving negative discharge performance should improve easily electric discharge
Amount, reduces difficult discharge capacity.Negative alloy powder of the present invention removes the segregation of the elements such as alloy surface cobalt, manganese, aluminium by alkali process,
So as to form one layer of rich nickel dam with higher catalytic activity in alloy surface, the electric conductivity between alloyed powder is improve.Together
When, because alloy surface layer hydrogenation produces more micro-crack, increase the specific surface area of alloy, so as to significantly improve alloy
The activity of electrode, improves the easy region of discharge capacity of negative pole, reduces difficult region of discharge capacity, therefore greatly improve the compound oxygen of negative pole
Ability and surface catalysis performance.
