High Purity Alumina for Lithium-Ion Battery Electrodes Separator
High Purity Alumina for Lithium-Ion Battery Electrodes Separator has the characteristics of insulation, heat insulation and high temperature resistance, it can be used in lithium battery separator coating. Uniform coating and good ductility to ensure battery safety.
Product Introduction
Product Introduction：
High Purity Alumina for Lithium-Ion Battery Electrodes Separator due to it has a plate like crystal structure. When the current is too large, the material heats up, and the high-purity nano-alumina coating material with the plate-like crystal structure will expand in volume, which will close the current conducting hole on the lithium battery separator. So as to play a role in blocking the current, when the temperature drops, the volume of the material will shrink, then the current conducting hole on the diaphragm will reopen.
Application Advantage:
1. When the current is too high, it can block the current. PP/PE material of lithium battery diaphragm is hole, when the current is too large, it is easy to cause perforation phenomenon, resulting in lithium batteries or explosion, burning with high purity alumina (vitamin k - L500G) used as coating material with adhesive coated in PP/PE material surface can have the effect of the hole, this is due to the high purity alumina into tabular crystal structure, when the current is too large, material heating, and tabular crystal structure of high purity nanometer alumina coating material volume expansion, will be closed on lithium battery diaphragm current conduction hole, which have the effect of blocking currents, when the temperature is lowered, The volume of the material will shrink, and then the current conduction hole on the diaphragm will reopen. The special physical and chemical properties of the material can greatly improve the safety performance of lithium battery, thus providing the possibility for high-power lithium battery with high energy safety and safe and reliable charging and discharging.
2. High purity alumina (VK-L500g) also has very good thermal conductivity, the battery temperature is too high, this material can be very good heat conduction, thus solving the poor thermal conductivity of PP/PE material.
3. The high purity alumina (VK-L500g) material also has excellent flame retardation, because the high purity alumina material itself is a very good flame retardant, even if the temperature is too high to reach the zero bound point of combustion, the good flame retardation performance of the material will prevent a wide range of combustion or even explosion.
