1. What is lithium nickel oxide powder?
Lithium nickel oxide is a layered transition-metal oxide with the chemical formula LiNiO₂. It is primarily researched as a positive-electrode/cathode material for rechargeable lithium-ion batteries.
2. What is the theoretical capacity of LiNiO₂?
LiNiO₂ has a theoretical specific capacity of approximately 274 mAh/g based on one lithium ion per formula unit. Practical reversible capacity depends strongly on electrode formulation, cycling conditions, particle morphology, and material quality.
3. Is LiNiO₂ the same as NMC cathode material?
No. LiNiO₂ contains lithium, nickel, and oxygen only, while NMC materials contain nickel, manganese, and cobalt in addition to lithium and oxygen. LiNiO₂ is often studied as a model nickel-rich layered oxide.
4. What particle size is available?
REG Metals can source LiNiO₂ in various fine and ultrafine particle-size ranges. Submicron through micron-scale powders and custom PSD specifications may be available depending on the manufacturer.
5. What specifications are important for battery-grade LiNiO₂?
Important specifications can include Li/Ni ratio, phase purity, cation mixing, particle-size distribution, tap density, surface area, residual lithium, moisture, and metallic impurities. For battery development, electrochemical performance data may also be requested.
6. Can REG Metals provide a Certificate of Analysis?
Yes. COA documentation is available as applicable, with chemical composition and other analytical properties reported according to the manufacturer's specification.
