sagger for high-nickel ternary material lithium battery lithium iron phosphate battery positive and negative materials
Product name : Lithium battery sagger
Specification : HY-TB-LDC
Casket for positive and negative electrode materials of lithium battery
Overview :
Lithium battery cathode material special sagger ( cordierite composite mullite material ) is suitable for cobalt oxide, lithium cobalt oxide, lithium manganate, ternary material, lithium iron phosphate and other cathode materials. The product process is special, the corrosion resistance is good, the thermal shock resistance is good, the slag is not oxidized, and the life is long. It has been successfully used by more than 60 % of domestic battery material suppliers for a long time.
The special sagger ( high purity corundum or graphite material ) for lithium battery anode materials is suitable for the professional firing of graphite anode materials. The products have obvious characteristics such as non-oxidation and long life.
The lithium low expansion crucible for lithium iron phosphate is a lithium low expansion crucible for lithium iron phosphate developed by our company. Combined with the nanomaterial increase technology, the crucible has super thermal stability and the thermal expansion coefficient is close to zero. It can be repeatedly cooled at 1000 °C without damage, and can be used in harsh environments such as rapid cooling and rapid heating. It is one of the most ideal kiln furniture materials, which is suitable for the dehydration of iron phosphate and the sintering of lithium iron phosphate.
