Description
Technical field
The utility model relates to a kind of equipment that is used for removing the dusty material magnetic metal impurity, particularly, relates to a kind of equipment that is used for removing the battery material magnetic metal impurity.
Background technology
As everyone knows, in battery, it is by the spontaneous result who carries out chemical reactions such as oxidation, reduction of inside battery that chemical energy directly changes electric energy into.This reaction is carried out on two electrodes respectively.Negative electrode active material by current potential negative and in electrolyte stable reducing agent form, positive active material by the current potential calibration and in electrolyte stable oxidant form, electrolyte then is the material with good ionic conductivity.
Along with the continuous development of battery technology, at present, no matter be galvanic cell or battery, positive and negative pole material uses dusty material mostly, the contact area of dusty material is big, purity is high, so the reaction of battery material is quick more and thorough, thereby improves the capacity of battery.
But, usually be mixed with impurity in the dusty material of battery, and impurity is the one of the main reasons that causes battery generation self-discharge phenomenon.Self discharge claims the electric charge hold facility again, and it refers under open-circuit condition, the hold facility of the electric weight of battery storage under the certain environment condition.Battery and galvanic cell be not when being connected with external circuit, and the battery capacity loss that is caused by inner spontaneous reaction is represented with the percentage of the capacity of annual or loss in every month.Generally speaking, self discharge mainly is subjected to the influence of manufacturing process, material, condition of storage, and as the self discharge of various lithium batteries all seldom, every month 5%-8%, metal-hydrogen nickel battery are then bigger, reach every month 12%-13%.
The generation of the self discharge of battery mainly contains two aspect reasons, be that impurity causes on the one hand, the free state foreign metal is in charging process, may be oxidized at positive pole, enter into electrolyte then, be reduced into metal at negative pole, discharge process is above inverse process, like this, when magnetic metal impurity forms charged movably ion, electronics shifted and cause self-discharge of battery; Be that other factors cause on the other hand, because the chemical reaction of inside battery is reversible, we can learn according to the characteristics of reversible reaction, inside battery is at every moment all reacting, there is ion-exchange, but this exchange will keep dynamic equilibrium, then can not keep balance completely in the reality, so there will be self-discharge phenomenon in battery.In the reason, impurity is main cause aspect above-mentioned two, and magnetic metal impurity occupies significant proportion in the impurity of battery material in impurity, and therefore, the magnetic metal impurity of removing in the battery material is extremely important.
The material of battery mainly is made up of raw materials such as positive powder material, negative pole powder material, barrier film, electrolyte, that is to say that the positive and negative pole material of battery adopts dusty material mostly.Therefore, remove magnetic metallic powder in the battery material and just remove magnetic metallic powder in the dusty material, correspondingly, need a kind ofly remove that the equipment of magnetic metal impurity comes the battery material degaussing in the dusty material.
At present, the existing electromagnetic filter of using comparative maturity in the prior art, but this equipment is primarily aimed at the application of removing magnetic metal impurity in the continuous fluid, it mainly is the application of removing iron, and this equipment is primarily aimed at continuous fluids such as pottery, mud and glaze, and is not suitable for solid powder material.
