Advanced materials for clean energy, electronics devices, and chemical applications

High-performance electrode material: The nickel metal hydride (NiMH) battery cathode is the micron size particles of carbonyl nickel powder. If the micron nickel powder replaced by nano- nickel powder, and assisted with appropriate technology, can create enormous surface area of the electrode. The nickel-hydrogen reaction is significantly increased in the specific surface area, which makes the corresponding of nickel metal hydride battery power increasing several times, and greatly improve charge and discharge efficiency. In other words, if the nano-nickel powder instead of the traditional micro nickel powder, the same capacity in the battery case, the size and weight of NiMH batteries can  greatly reduced. This high capacity, small size, light weight nickel-metal hydride battery, will have a more wider use.

Efficient catalysts: The large and highly active surface area, nano nickel powder has a greatly enhancement catalytic efficiency. Instead of conventional micro nickel powder can be used for hydrogenation of organic compounds. In the vehicle tail gas treatment nano nickel can replace the precious metals such as platinum and rhodium, so that the cost can be greatly reduced.

Magnetic fluid: Nickel and its alloy powders can be prepared as nano-magnetic fluid production used in sealing, medical equipment, sound regulation, mechanical control and other fields.

Conductive paste: Electronic paste is widely used in microelectronics industry packaging, connectivity, miniaturization of microelectronic devices. Nickel powder with nano-electronic paste has superior performance as micro nickel powder. It is widely used in MLCC.

Sintering additives: Nano-powder has large volume ratio of surface atoms, which have so high energy state. In the powder metallurgical industry, it can be used as sintering additive to reduce sintering temperature in ceramic and diamond tools production.

Non-metallic conductive coatings: The high surface energy of nano-Nickel can be spray at lower temperature than its bulk melting point at non-metallic devices surface to enhance the electric conductivity under anaerobic conditions. The coating can improve the oxidation resistance, corrosion.

 Magnetic recording: Nano nickel powder can be used as high-performance magnetic recording materials. It can improve the density several times of storage information tapes, and hard and soft disk.

Combustion efficiency: The nano-nickel powder added to the solid fuel rocket propellant can significantly improve the efficiency of combustion of fuel, improve combustion stability.
