Description
Technical field
The present invention relates to fire resisting material field, in particular to a kind of compound saggar, preparation method and applications.
Background technology
At present, cobalt acid lithium and ternary lithium battery are the domestic positive electrodes for widely using lithium battery at present, and most
The production of positive electrode is all made of in the synthesis process, to hold the saggar of burning in flame-proof kiln with high temperature solid phase synthesis
Material is generally based on cordierite, mullite, quartz and corundum, with cordierite composite mullite matter saggar in these materials
Products application it is most wide.The type saggar is using cordierite, mullite and corundum as raw material, adds in part of clay and micro mist
As bonding agent, the compression moulding under high tonnage press after room temperature conserves, reenters flame-proof kiln progress high temperature firing and production is made
Product.Also, the average index of domestic and international saggar consumption is that positive electrode per ton consumes 200-300 kilograms, and dosage is very big.
Mullite Cordierite Basic Sagger prepared by traditional handicraft has shortcomings, first, traditional mullite cordierite
The porosity of matter saggar is high, bulk density is small, and internal impurity component height easily issues biochemistry with the active element high temperature in lithium battery
Reaction is learned so as to cause the service life of saggar not long and easily be corroded, corrosion causes the peeling of saggar to fall into lithium battery anode material
In material, battery purity is influenced；Secondly, during mechanical pressing in order to ensure processability, it is necessary to add in kaolin and silicon is micro-
Powder class bonding agent, and easily with the elemental lithium in lithium battery occurs for such bonding agent making for chemical reaction influence saggar at high temperature
Use the service life.Above-mentioned factor ultimately results in not strong saggar corrosion-proof type, short life, thermal shock resistance difference and easy pollution is used for multiple times
Battery raw material.
Saggar passes through cold and hot reuse, and most saggars does not exceed 20 times, generally also just at 15 times or so just
It can scrap.There are two the reason for causing such case：First, saggar recycles in high temperature kiln；Second is that anode material under high temperature
Material is to the peeling caused by the erosion of saggar.In actual production, often the combined influence of two factors causes saggar to use
Service life is not high.The positive electrode of lithium battery first corrodes saggar, and especially the oxidate for lithium under high temperature has very high activity,
It can be reacted with the refractory material in saggar, the liquid phase of similar glassy state be generated under high temperature, these liquid phase ingredients are in the variation of viscosity
The solid phase surface of continuous erosion saggar down, and the stomata on saggar surface can also provide passage for these erosions, with the time
Accumulation, the alkali metal oxide of similar glassy state constantly permeates toward saggar depths, this passage is more and more deeper, corrodes and generates
Impurity it is more and more, generation eucryptite, lithium metasilicate, the eutectics ore deposit phase such as lithium aluminosilicate, along with saggar in kiln into
Go out out, the coefficient of expansion of impurity ore deposit phase has a larger difference with saggar, and hot and cold alternation is so as to causing the peeling on saggar surface, cracking etc.
Phenomenon, so as to affect the service life of saggar.
In view of this, it is special to propose the present invention.

Performance test
In order to which the advantageous effect to compound saggar provided by the invention is further detailed, tested as follows：
The saggar in embodiment 1-18 and comparative example 1-7 is tested for the property respectively, for synthesize 811 (with nickel, cobalt,
Manganese is sequence) type nickel cobalt manganese lithium ion battery ternary material, then count each saggar service life (occur being broken with saggar so that
Subject to saggar partial exfoliation, breakage) and observation using the surface state of saggar after 10 times, test result such as 1 institute of table
Show.
1 saggar the performance test results of table
From the test result of table 1, the service life of the compound saggar in embodiment 1-18 and saggar after 10 times is used
Surface state be superior to comparative example 1-7, illustrate compound saggar provided by the invention pass through each raw material reasonable cooperation, have make
The advantages of with long lifespan, changes the content of each raw material or deletes wherein arbitrary raw material or use existing saggar, service life
It can shorten.Compound saggar in embodiment 1-18, without peeling, without dusting, illustrates that its corrosion resistance is good after using 10 times.
Further analysis shows that the preparation method that the saggar in embodiment 9-18 employs the present invention is prepared, make
It is longer than the service life of embodiment 1-8 respectively with the service life, illustrate the preparation method rational technology of the present invention, fully consider each original
Expect the property of itself, can further extend the service life of saggar.The addition of the spent pulping liquor of embodiment 17 and 18, maintenance
In currently preferred scope, service life is longer than embodiment 12 and 16 respectively for time, firing temperature and soaking time,
Illustrate that the service life for the saggar being prepared using the preferred embodiment of the present invention is longer.
Although illustrate and describing the present invention with specific embodiment, it will be appreciated that without departing substantially from the present invention's
Many other change and modification can be made in the case of spirit and scope.It is, therefore, intended that in the following claims
Including belonging to all such changes and modifications in the scope of the invention.
