LiNbO3-coated NMC532, NMC532

General Description
Lithium niobate coated NMC532 is a powdered form of lithium nickel manganese cobalt oxide with a stoichiometry of 5:3:2 Ni:Mn:Co and a typical particle size of 4-10 microns. The particles are coated in 5-10 nm amorphous lithium niobate, less than 1 wt.%.

Applications
LiNbO3-coated NMC532 is a high-performance cathode active material designed to be used in lithium-ion batteries (LIBs), particularly solid-state batteries and high-voltage LIBs. NMC532 balances the high capacity bestowed by 50% nickel with the structural stability imparted by the manganese and cobalt. Compared to NMC811, NMC532 tends to achieve better cycling lifetime and coulombic efficiencies. The LiNbO3-coating boosts the stability of the cathode material by protecting the electrode and electrolyte from unwanted reactions. Research indicates that the lithium-niobate coating, increases the capacity over time (less capacity fade) by mitigating reactions between the electrolyte and cathode material and by impeding the release of metal ions from the NMC cathode into the electrolyte. Additionally, the lithium-niobate coating, sometimes called a LiNbO3 insertion layer, improves the rate capability by reducing the space charge layer barrier at the electrolyte/cathode interface. This improvement is evidenced both in enhanced Li diffusion and smaller electrode polarization.

Features & Benefits

• NMC532 balances high capacity and long cycle lifetimes
• LiNbO3 coating protects the cathode and electrolyte, improving coulombic efficiency
• LiNbO3 insertion layer improves rate capability

LiNbO3-coated NMC622, NMC622

General Description
Lithium niobate coated NMC622 is a powdered form of lithium nickel manganese cobalt oxide with a stoichiometry of 6:2:2 Ni:Mn:Co and a typical particle size of 4-10 microns. The particles are coated in 5-10 nm amorphous lithium niobate, less than 1 wt.%.

Applications
LiNbO3-coated NMC622 is a high-performance cathode active material specially designed for lithium-ion batteries (LIBs), particularly solid-state and high-voltage batteries. With a balance of 60% nickel for high capacity and 40% manganese and cobalt for structural stability, NMC622 surpasses NMC811 in terms of cycling lifetime and coulombic efficiencies and offers higher capacity than NMC532. The LiNbO3 coating plays a vital role in enhancing the stability of the cathode material by safeguarding the electrode and electrolyte from undesired reactions. Research suggests that this lithium-niobate coating mitigates reactions between the cathode material and electrolyte, reducing capacity fade over time and impeding the release of metal ions from the NMC cathode. Additionally, the LiNbO3 “insertion layer” improves rate capability by minimizing the space charge layer barrier at the electrolyte/cathode interface. This advancement translates to superior Li diffusion and reduced electrode polarization.

Features & Benefits

• NMC622: High capacity and long cycle lifetimes
• LiNbO3 coating: Enhanced protection for cathode and electrolyte, leading to improved coulombic efficiency
• LiNbO3 insertion layer: Boosts rate capability

LiNbO3-coated NMC811, NMC811

General Description
Lithium niobate coated NMC811 is a powdered form of lithium nickel manganese cobalt oxide with a stoichiometry of 8:1:1 Ni:Mn:Co and a typical particle size of 4-10 microns. The particles are coated in 5-10 nm amorphous lithium niobate, less than 1 wt.%. Our NMC811 has a minimum nickel content of 80.0% of the metal content (≥48.2 wt% overall), translating to a nickel-rich composition between NMC811 and NMC85:05:10.

Applications
Lithium niobium oxide-coated NMC811 is a high-performance cathode material for solid-state and high-voltage lithium-ion batteries (LIBs). With 80% nickel content, NMC811 offers superior specific energy compared to NMC111, NMC532, or NMC622. The LiNbO3 coating enhances cathode stability by protecting the electrode and electrolyte from undesired reactions. Research suggests that this coating reduces capacity fade over time and restricts the release of metal ions from the NMC cathode, mitigating reactions with the electrolyte. The LiNbO3 “insertion layer” further improves rate capability by minimizing the space charge layer barrier at the electrolyte/cathode interface, leading to enhanced Li diffusion and reduced electrode polarization.

Features & Benefits

• NMC811 gives high specific energy density
• LiNbO3 coating safeguards cathode and electrolyte, enhancing coulombic efficiency
• LiNbO3 insertion layer enhances rate capability
