Nano nickel powder

1, high-performance electrode materials, in the fuel cell can replace the precious metal platinum, thereby reducing the cost of fuel cells.
If the micron-level nickel powder is replaced by nano-level nickel powder, and supplemented by appropriate processes, electrodes with a huge surface area can be manufactured, so that the specific surface area involved in the nickel-metal hydride reaction is increased, which makes the power of nickel-metal hydride batteries increase several times , and improve the charging and discharging efficiency. In other words, if the nano-nickel powder replaces the traditional carbonyl nickel powder, the size and weight of the nickel-metal hydride battery can be reduced under the condition that the battery capacity is unchanged. This kind of nickel-metal hydride battery with large capacity, small size and light weight will have a broader use and market. Nickel-metal hydride batteries are the safest, most stable, and most cost-effective green environmental protection batteries in secondary rechargeable batteries.
Moreover, nano-nickel is an irreplaceable catalyst in fuel cells for various fuel cells (PEM, SOFC, DMFC). The use of nano-nickel as a catalyst for fuel cells can replace the expensive metal platinum, which can reduce the manufacturing cost of fuel cells. With nano-nickel powder supplemented by appropriate processes, electrodes with huge surface areas and holes can be manufactured, and such high-performance electrode materials can improve discharge efficiency. It is an indispensable and important material for the manufacture of hydrogen fuel cells. Fuel cells can provide a stable power supply in the military, field operations, islands, etc. In the green environmental protection of transportation tools, community energy, home and building power supply, heating and so on has a very large application prospects.
2. Magnetic fluid, radiation-proof functional fiber.
3, high efficiency catalyst, due to its special small size effect, used in catalysts, can be many times higher than the catalytic efficiency of ordinary nickel powder, used in organic hydrogenation reaction.
4, conductive paste, can replace silver powder for large-scale integrated circuit boards, printed circuit boards, used in microelectronics industry wiring, packaging, connection, etc., plays an important role in the miniaturization of microelectronic devices, MLCC, so that MLCC devices miniaturization.
5. Powder forming, injection molding filler, used in electrical alloy industry, powder metallurgy.
6, sintering additives, used in diamond tool manufacturing, in the diamond tool to add an appropriate amount of nano nickel powder can improve the sintering temperature and sintering density of the tool, improve the quality of the tool.
7. Conductive coating treatment of metals and non-metals, etc.
8. Special coatings, as selective solar absorbing coatings, are used in solar manufacturing.
9. Absorbing material, which has a strong absorption capacity for electromagnetic waves, can be used in the field of military stealth.
10, magnetic fluid, used in sealing shock absorption, sound change, light display and other fields
11, combustion aids, the nano nickel powder added to the rocket’s solid fuel propellant can improve the fuel combustion rate, combustion heat, improve the stability of combustion.
12. Magnetic materials, due to their small particle size and physical magnetism, nano nickel powder as a magnetic material is used in the field of biomedicine, as a variety of anti-cancer drug carriers, forming a magnetic targeted drug delivery system; Magnetic beads made of nano-nickel powder magnetics can also be used in the isolation of magnetic immune cells, nuclear magnetic resonance imaging and other aspects. The magnetic properties of nano-nickel powder can generate heat under the action of more alternating electromagnetic fields, kill tumor cells, and achieve the purpose of treating tumors.
13, magnetic therapy health care field: as we all know, the human body has a biological magnetic field, every cell of the human body is a magnetic microunit, so changes in the external magnetic field will affect the physiological function of the human body. It has been reported that the magnetic field has an influencing effect on the human nervous system, heart function, blood composition, vascular system, blood lipids, blood rheology, immune function, endocrine function and activity. Thus, it has a disease treatment and health care effect on the human body. Based on this principle, people add nano-nickel powder to products to adjust human body functions and improve disease resistance, playing a role in health care. There are also some application products of nano magnetic materials on the market, such as nano magnetic therapy products, nano magnetic therapy knee pads, nano magnetic therapy bracelets, etc.
