Description
Technical field
The present invention relates to secondary cell and make the field, be meant the Ni-MH battery of electric current quick charge greatly especially.
Background technology
Ni-MH battery is the substitute products of early stage nickel-cadmium cell, similar on Ni-MH battery and the nickel-cadmium cell profile, and the positive pole of Ni-MH battery and nickel-cadmium cell are also basic identical, all be to be anodal with the nickel hydroxide, what the main distinction was the employing of nickel-cadmium battery negative pole plate is the cadmium active material, and Ni-MH battery is to be negative pole with the high energy hydrogen-storage alloy, so Ni-MH battery has bigger energy.Simultaneously Ni-MH battery is also similar substantially to nickel-cadmium cell aspect electrochemical properties, thus Ni-MH battery replacement nickel cadmium cell fully in use, and do not need equipment is carried out any transformation.It is the battery of at present environmental protection, does not re-use poisonous cadmium, can eliminate the pollution problem that heavy metal element brings environment.Ni-MH battery has bigger energy density ratio, this means to use Ni-MH battery can prolong the operating time of equipment effectively not for digital equipment increases under the situation of additional weight.Simultaneously Ni-MH battery is also similar substantially to nickel-cadmium cell aspect electrology characteristic, fully can the replacement nickel cadmium cell when practical application, and do not need equipment is carried out any transformation.Another advantage of Ni-MH battery is: reduced to exist in the nickel-cadmium cell " memory effect " greatly, this can use Ni-MH battery more easily.
At present, an important use of Ni-MH battery is to be applied in the field of power tools, because wireless chargeable electric tool fast development in recent years brings great convenience to people.And electric tool in use requires big flow discharge, in addition, also requires Ni-MH battery should have big flow charge function in order to shorten the charging interval.Yet the charging current that existing ni-mh secondary rechargeable battery can bear is little, and the charging consumption time is long, and large current charge efficient is low and security performance is low.
Summary of the invention
The object of the present invention is to provide a kind ofly can with big electric current battery be full of electricity at short notice, and the high nickel hydrogen quick charging battery of charge efficiency.
The present invention also aims to provide the manufacture method of above-mentioned nickel hydrogen quick charging battery.
For achieving the above object, solution of the present invention is:
A kind of nickel hydrogen quick charging battery comprises positive pole, negative pole, electrolyte and battery diaphragm;

2+(1.3-1.7wt%), and add the Ni (OH) that percentage by weight is 6% CoO
2Described additive is a nickel simple substance, and content is Ni (OH)
2The 1%-10% of total weight;
Described electrolyte is two yuan of electrolyte being made up of two kinds of materials among KOH, NaOH or the LiOH.
Described density of electrolyte is 1.28g/ml, OH
-Molar concentration is 9.5mol/L.
Described binding agent is a polytetrafluoroethylene.
The manufacture method of described nickel hydrogen quick charging battery may further comprise the steps:
The first step adopts and contains Zn
2+(3.7-4.3wt%), Co
2+(1.3-1.7wt%), and add the Ni (OH) that percentage by weight is 6% CoO
2As the positive active material of battery, add percentage by weight again and be 1%-10% nickel simple substance as additive, PTFE (polytetrafluoroethylene) dry powder blend that adds 0.5wt% becomes anodal material;
Second step was coated to the positive pole material on the anodal matrix, passed through roll-in and cut operation and make battery positive plate;
The 3rd step stacked gradually the formation electrode group of reeling with positive plate, diaphragm paper, negative plate, and electrode is assembled in the battery steel shell;
The 4th step, inject electrolyte, the enclosed cell housing changes into through overcharging and promptly to produce nickel hydrogen quick charging battery.
After adopting such scheme, though the present invention is structurally consistent with existing nickel-hydrogen secondary cell, but owing to added percentage by weight in positive pole is 6% CoO and the nickel simple substance of 1%-10%, and improved the prescription of electrolyte, thereby the charging current of bearing that the existing ni-mh secondary rechargeable battery of solution exists in charging process is little, the problem that the charging consumption time is long reaches the purpose of quick charge.
