Abstract
The utility model relates to a battery cathode material auxiliary device technical field, concretely relates to special casket-like bowl of lithium electricity cathode material, including the casket-like bowl, the casket-like bowl both sides are equipped with the mounting hole, both sides be equipped with the gas pocket stick between the mounting hole, the gas pocket stick evenly is equipped with a plurality of gas pockets, be equipped with the through-hole in the middle of the gas pocket stick, the utility model discloses because the gas pocket stick has in the casket-like bowl, this kind of casket-like bowl is because the material of dress is very thick in sintering process like this, can let gas and casket-like bowl center and bottom material more abundant contact, and this electrical property that can promote cathode material also can reduce lithium-nickel mixed row and so on including promoting capacity, first efficiency, cyclicity ability. Therefore, the performance of the material is greatly improved, the utilization rate and the capacity of the saggar are improved, and the cost of enterprises is reduced.
Description
Technical Field
The utility model relates to a battery cathode material auxiliary device technical field, concretely relates to special casket-like bowl of lithium electricity cathode material.
Background
Lithium electricity anode material has lithium nickelate, lithium nickel manganese manganate, lithium nickel cobalt manganese manganate, lithium cobaltate, lithium manganate, lithium iron phosphate, these several kinds of materials of rich lithium manganese are used in digital field, electric tool, electric bicycle, electric automobile, fields such as energy storage market, need the casket-like bowl of dedicated splendid attire anode material in the sintering anode material process, the casket-like bowl that adopts in the present market all is square or rectangular casket-like bowl, this kind of casket-like bowl is very thick owing to the material of dress in the sintering process in the kiln, can not let gas and casket-like bowl center and bottom material contact, this can cause the deterioration of anode material's electrical property, the capacity is low, first inefficiency, lithium nickel is arranged seriously, the cyclicity can be poor etc..
Disclosure of Invention
According to the problem that the background art provided, the utility model provides a special casket-like bowl of lithium electricity cathode material solves, it is right next the utility model discloses do further to explain.
The special sagger for the lithium battery positive electrode material comprises a sagger body, wherein mounting holes are formed in two sides of the sagger body, an air hole rod is arranged between the mounting holes in the two sides of the sagger body, a plurality of air holes are uniformly formed in the air hole rod, and a through hole is formed in the middle of the air hole rod;
preferably, the thickness of the side wall and the bottom of the sagger is 2-10 um;
preferably, the air hole rod is positioned at the position of 1/2 of the height of the sagger;
preferably, the diameter of the air hole rod is 2-5cm, and the size of the air hole is 10-100 um;
preferably, the air hole rod is made of corundum;
preferably, the sagger is conical;
preferably, rounding is carried out on the periphery of the sagger;
has the advantages that: compared with the prior art, the utility model discloses because the gas pocket stick has in the saggar, this kind of saggar is very thick owing to the material of dress in sintering process like this, can let gas and saggar center and the more abundant contact of bottom material, and this can promote anode material's electrical property, including promoting capacity, first efficiency, cyclicity ability, also can reduce lithium nickel and thoughtlessly arrange and so on. Therefore, the performance of the material is greatly improved, the utilization rate and the capacity of the saggar are improved, and the cost of enterprises is reduced.
