Description
Technical field
The present invention relates to a kind of lean property aluminium titanate composite material saggar, especially lithium battery with extra-strong corrosion resistant are special
The manufacturing method of saggar and application.
Background technology
With deepening continuously for lithium battery applications, usage amount increases year by year, and China is as lithium battery big producer, in the world
Key player is play in lithium battery production.Lithium battery type is various, and because of positive electrode difference, lithium ion battery is broadly divided into：
LiFePO4 (LFP), lithium nickelate (LNO), LiMn2O4 (LMO), cobalt acid lithium (LCO) and nickel cobalt mangaic acid ternary lithium (NCM), nickel
Cobalt aluminic acid ternary lithium (NCA), negative material mainly use graphitic carbon material.Wherein nickel cobalt mangaic acid ternary lithium (NCM), nickel cobalt aluminic acid
The features such as ternary lithium (NCA) is high, cycle-index is long with energy density, becomes the developing direction of the following lithium battery.Lithium battery to
Life is while offer convenience, production process can not avoid there are problems of energy consumption, wherein being mainly reflected under high temperature solid
Phase reaction is sintered, and in addition to the consumption of electricity in whole process, the main consumable material of another part is exactly kiln and kiln furnitures, wherein again
It is consumed using the saggar being in direct contact with lithium battery raw material as serious.The most of Anode of lithium cell material are currently on the market
Cordierite-mullite, mullite corundum sagger, such saggar have coefficient of expansion low-heat pinking good, and cost of material is low and is easy to get
The advantages that, other than ternary lithium battery, it is used as common Anode of lithium cell material sintering, service life is about 20 times or so, but
If being used as the container of ternary anode material of lithium battery reaction-sintered, service life is about 10 times, mainly scraps reason and is：
Ternary lithium battery raw material and refractory material reaction, produce a kind of erosion layer of glass phase substance, corrode the big thermal shock of the layer coefficient of expansion
Property difference it is easy to crack, and there are larger differences with the coefficient of expansion of original saggar ligand, it is easy to which the cracking pollution lithium battery that falls off is former
Material.It is all nickeliferous in ternary Anode of lithium cell material, it is needed using the saggar scrapped as trade waste as chemical treatments,
Not only processing cost is high, and easily causes the generation of secondary pollution.The service life of ternary lithium battery saggar is improved,
Through developing faced one of main pressure as current ternary lithium battery.The average index of domestic and international saggar consumption be it is per ton just
200-300 kilograms of pole material consumption causes prodigious pressure to environment, researches and develops the special casket of a suitable lithium battery sintering
Alms bowl is imperative.
By the analysis of lithium battery material material, it is found that lithium battery needs coefficient of expansion low-heat pinking good and resistance to saggar
Alkali, the lithium in common lithium battery are introduced in the form of lithium carbonate, alkalinity is smaller, but lithium is introduced as hydrogen in ternary lithium battery
Lithia, alkalinity is very big, and the ceramic materials such as mullite are typically all acidproof not alkaline-resisting, and especially under high temperature, alkali is to such material
Erosion it is very big.In terms of alkali resistance, there is a kind of ceramic material that there is very excellent performance, that is, aluminium titanates.Aluminium titanates
Mainly using ionic bond and covalent bond as associative key, from microstructure and state, there are crystal phase and stomata in inside, this is just
Determine aluminium titanates have the low thermal coefficient not available for metal material and high molecular material, anti-slag, it is alkaline-resisting, anti-corrosion, to more
Kind metal and glass have nonwettable advantage, therefore in the conditions harsh environment such as wear-resistant, high temperature resistant, alkali resistant, anticorrosive
Under have a wide range of applications, it is that the coefficient of expansion is minimum in known ceramic material especially to require the occasion of highly heatproof and shockproof, aluminium titanates
's.The disadvantages such as aluminium titanates also has 1100 DEG C or so easily to decompose simultaneously, and mechanical strength is low, so being difficult to obtain under pure aluminium titanates room temperature
, mechanical strength is very low, lacks practical utility value, stablizes and the aluminium titanates with good mechanical strength is generally with composite material
Form exist, aluminium titanate composite material not only has an above-mentioned advantage of aluminium titanates, while the shortcomings that evaded itself very well, this
Class aluminium titanate composite material is undoubtedly a kind of raw material being highly suitable for lithium battery industry saggar.But aluminium titanates composite wood
Material belongs to non-plastic raw material, does not have plasticity.
