The uses of high-purity nickel include:
I. Battery power
-
Used as a cathode material for lithium-ion batteries — it offers high stability, good partial-discharge performance, long cycle life, high anode reaction activity, and a smooth voltage curve; therefore it is applied in mobile power banks and energy storage batteries.
-
Used as a cathode material for lithium cobalt titanate, it can be widely applied in electric vehicles, automobile batteries, and home energy storage devices. It has good cycling characteristics, low energy consumption, high safety, and strong discharge capability.
II. Information products
-
Used as a raw material for amplifier circuits and chips, it can meet certain circuit functional requirements and improve component performance; it is widely used in information products such as smartphones, laptops, and smart home devices.
-
Used as the anode material for organic electroluminescent displays, leveraging nickel’s chemical bonding properties to make OLEDs (organic light-emitting diodes) emit light; it can be used in smaller screens and portable devices whose performance varies with ambient temperature.
III. Energy harvesting
-
Used as the anode material for solar panels, it can effectively absorb solar energy and convert it into electrical energy, making it a choice for energy-harvesting devices operating under harsh outdoor conditions.
-
Used as a raw material for specialty electrostatic storage devices, it can efficiently accumulate and reuse electrical energy repeatedly. It features miniature size, large storage capacity, short charging time, and very high high-frequency lifespan, so it can be widely applied in various industrial wireless technologies.
IV. Other uses
-
Used as the anode material for graphene semiconductor chips, it can improve the voltage-withstand and loss performance of graphene semiconductor chips, thereby supporting development in high-tech fields such as solar power generation, military technology, and aerospace.
-
Used as a raw material for medical devices, food containers, and environmental protection equipment, it offers corrosion resistance, fouling resistance, acid and alkali resistance, and resistance to hot-water bath treatments, therefore satisfying special safety and rapid-response requirements.
