Abstract
The invention provides a loading saggar for sintering during the preparation of anode materials of lithium-ion batteries. The loading saggar is made of nickel metal or nickel alloy and can be used in the sintering process of anode materials of lithium-ion batteries with a sintering temperature not higher than 1100 oC. The saggar has favorable thermal conductivity; primary particles of the anode material after sintering are uniform in size, and the sintering time is short; the thermal capacity is low, and the comprehensive unavailable energy can be reduced by more than 20%; slag won't come off easily, and the anode materials contain few impurities during sintering; the saggar has a long service life, and can be reused for more than 200 times; the saggar is alkali resistant, and waste saggar can be recycled as valuable resources, so no waste will be generated. Therefore, the saggar can bring favorable social and economic benefits.
Description
Technical field
The present invention relates to inorganic chemical industry new energy materialses field is and in particular to one kind prepares lithium ion cell positive
The charging saggar of sintering in materials process.
Background technology
Lithium ion battery emerged over more than 20 year, because its energy density is high, had extended cycle life, and had obtained wide
General application.Batteries of electric automobile, energy storage, artificial intelligence's equipment etc. also will widely apply lithium ion battery,
Its demand will be very huge, and along with the growth of lithium ion battery, its positive electrode demand also will therewith
Expand, preparing the sinter burden saggar demand during positive electrode will constantly increase.
At present, in anode material for lithium-ion batteries sintering process, the material of charging saggar is substantially all and adopts violet
Blue or green mullite.However, violet green grass or young crops mullite poor heat conductivity, its thermal conductivity only has 1.5-2.42w/ (m k), from
And cause saggar bottom and surrounding heat transfer slow, extend material heat time heating time in saggar, and material is heated not
Uniformly, so affect saggar in the upper and lower quality of material inconsistent, the particle size range of material primary particle is relatively wide
General；Violet green grass or young crops mullite sagger specific heat capacity is big, generally at 800-1100j/ (mol k), meeting when using every time
Substantial amounts of heat is had to be absorbed by saggar and lead to thermal waste；Violet green grass or young crops mullite sagger easily falls during using
Slag, thus can cause the material in saggar to contain the impurity that saggar falls down；Violet green grass or young crops mullite sagger uses the longevity
Life generally only 20 times about, can produce intractable hazardous waste in a large number.
The material of charging saggar also has and adopted corundum, carborundum etc. on a small quantity, but they equally exist and use the longevity
Life poor, easily split, perishable the shortcomings of.
Content of the invention
It is an object of the invention to provide a kind of charging preparing sintering during anode material for lithium-ion batteries
Saggar, is raw material using nickel metal or nickel alloy, can significantly improve anode material for lithium-ion batteries quality,
Reduce production cost and energy consumption, reduce the generation of hazardous waste, there are good social and economic effects.
To achieve these goals, the technical solution used in the present invention is as follows:
A kind of charging saggar preparing sintering during anode material for lithium-ion batteries, is closed by nickel metal or nickel
Gold is made.

According to above scheme, in described nickel metal, the mass content of nickel is more than or equal to 98%.
According to above scheme, in described nickel alloy, the mass content of nickel is more than or equal to 40%.
According to above scheme, the saggar wall thickness that feeds is less than or equal to 10 millimeters.
According to above scheme, the saggar that feeds is shaped as square or circular.
According to above scheme, the saggar that feeds is used for the lithium ion cell positive of not higher than 1100 degree of sintering temperature
Material, such as cobalt acid lithium, two-spot or multielement ma-terial, LiFePO4, LiMn2O4 etc..
The present invention adopts nickel metal or nickel-base alloy manufacture, can significantly improve violet green grass or young crops mullite sagger above-mentioned scarce
Fall into.
The invention has the beneficial effects as follows:
1) present invention has good heat conductivity, its thermal conductivity about at 60-100w/ (m k), after sintering
Material primary particle size very uniform, maximum sintering temperature falls on a year-on-year basis, and sintering time is also accordingly short；
2) there is relatively low thermal capacitance, at 410-450j/ (mol k), comprehensive useless energy consumption reduces by 20% to its specific heat capacity
More than；3) it is not easy scaling-off, the impurity in positive electrode during sintering is less；4) long service life is permissible
Reuse more than 200 times, and violet green grass or young crops mullite sagger access times only have 20 times about；5) resistance to highly basic
Corrosivity；6) saggar that gives up can reuse as valuable resource, will not produce garbage, more will not produce
Raw hazardous waste, has good environmental conservation effect.In a word, the present invention can improve positive electrode quality,
Reduces cost, reduces energy consumption, improves production capacity, has good economic and social benefit.
