The battery-specific nano zirconia
powder has fine nanometer particle size, uniform particle size distribution, no
hard agglomeration and good sphericity. In the production, the content of each
component is precisely controlled, the uniform mixing of particles between
different components is realized, and the particle size, shape and structure
are strictly controlled to ensure the quality of the product. This product is
used for electrode manufacturing in high performance solid batteries by doping
the conductive properties of different elements.
The nano-zirconia battery consists of a
solid zirconia electrolyte (mostly yttrium-stabilized zirconia powder, YSZ for
short) and two platinum electrodes. The yttrium-stabilized nano-zirconia powder
has been widely used in the field of solid oxide fuel cells because of its high
oxygen ion conductivity and ideal stability in a redox atmosphere.

Application features:
1. Battery-specific nano-zirconia has
high oxygen ion conductivity, excellent mechanical properties and good redox
stability under high temperature conditions.
2. Improved zirconia concentration
battery type oxygen detector made of battery-specific nano zirconia can
effectively extend the life of the product, improve accuracy and reduce
maintenance.
3. As an electrolyte, the battery is widely
used as an ideal electrolyte in solid oxide fuel cells. It is used to transfer
the oxygen ions generated by the reaction. At a high temperature of 800~1000
degrees Celsius, the ions can penetrate the ceramic material.
4. The battery-specific nano-zirconia
can also produce active element effect after covering or dispersing on the
surface of the alloy, which can significantly improve the high temperature
oxidation resistance of the alloy and greatly improve the adhesion of the oxide
film.
5. Nano-zirconia is currently the most
used electrolyte material, and the long-term stability of YSZ structure and
properties is critical to the reliability of solid oxide fuel cell systems.
6. Battery-specific nano-zirconia (YSZ)
is widely used in the manufacture of solid oxide fuel cells (SOFC), oxygen
sensors and microelectronic devices.
