Description
Technical field
The invention belongs to battery manufacture Material Fields, and in particular to a kind of mixture of powders of water activated battery.
Background technology
The effective life of common batteries on the market is 3-5 at present, there is electricity during general common batteries application
The situation of pond leakage, therefore service life is shorter.And the water activated battery occurred on the market is there are capacity is low, the feelings such as of poor quality
Condition as the capacity of 50-14 only has 400mAh, and is susceptible to the phenomenon of leakage when in use.Emergent energy on the market now
Bag is required for direct current to be charged in emergency circumstances using, it is necessary to carry out periodic maintenance and just can guarantee.
In traditional water activated battery powder manufacture craft, water activated battery powder by special drying condition without handling
Storage time can be caused short, water activated battery powder can cause the energy of water activated battery without the attrition process Jing Guo fine condition
Density is low, and then influences the storage time and using effect of water activated battery.
Therefore, it is necessary to a kind of raising water activated battery shelf lifes, reduce battery leakage and mistake caused by own loss
Imitate phenomenon incidence.Manufacture easy to produce simultaneously, and the water activated battery making material of contamination-free generation, to solve existing skill
It is insufficient present in art.
The content of the invention
The purpose of the present invention is that solve the above-mentioned problems and provides a kind of mixture of powders of water activated battery.
The present invention is achieved through the following technical solutions above-mentioned purpose：
A kind of mixture of powders of water activated battery, is made of following raw material：Manganese dioxide, acetylene black, zinc chloride, sulfuric acid
Barium, carboxymethyl cellulose.
Further, the mass fraction of the raw material is：60-75 parts of manganese dioxide, 5-15 parts of acetylene black, zinc chloride 10-
20 parts, 1-5 parts of barium sulfate, 1-5 parts of carboxymethyl cellulose.
Preferably, 75 parts of manganese dioxide, 8 parts of acetylene black, 15 parts of zinc chloride, 1 part of barium sulfate, 1 part of carboxymethyl cellulose.
Preferably, 68 parts of manganese dioxide, 15 parts of acetylene black, 15 parts of zinc chloride, 1 part of barium sulfate, 1 part of carboxymethyl cellulose.
The grain size of the mixture of powders is 20-30 mesh.
A kind of preparation method of the mixture of powders of water activated battery after above-mentioned raw materials are mixed according to proportioning, is put into
When grinding 1-2 is small in ball mill.
The grinding carries out under conditions of 15-30 DEG C of environment temperature, relative humidity is 0%-15%RH.
After grinding, mixture is passed through into 20-30 mesh sieves.
Advantageous effect is：
1st, the water activated battery electrode material that produces of the present invention can improve the water activated battery shelf life, reduce battery because
Leakage caused by own loss and failure phenomenon incidence；
2 while manufacture easy to produce, and contamination-free generates, and be easily recycled；
3rd, power supply performance is stablized.
