LNMO-610 Cathode Active Material (LiNi₀.₅Mn₁.₅O₄) Powder

Overview

LNMO-610 (LiNi₀.₅Mn₁.₅O₄) is a high-voltage spinel lithium-ion cathode active material used in 5 V-class cathode research. Compared with layered NMC/NCA materials, LNMO adopts a spinel structure that provides three-dimensional lithium-ion transport pathways. This makes it a strong candidate for studies focused on power capability, fast-charge behaviour, and high-voltage electrolyte stability, while remaining cobalt-free.

Working mechanism

During charge and discharge, Li⁺ reversibly intercalates/deintercalates within the spinel lattice. The electrochemical response is dominated by the Ni²⁺/Ni⁴⁺ redox couple at high potential, while the robust spinel framework supports efficient ion transport and good rate performance. In practical cells, interfacial stability at high voltage is often the key performance limiter, so LNMO is widely used to evaluate electrolyte formulations, additives, and surface/interface engineering strategies.

Key specifications

• Appearance: grey-black powder; uniform colour; no caking
• Tap density: > 1.2 g/cm³
• Particle size (µm): D10 > 0.8; D50 = 3.0–6.5; D90 < 15.0
• First discharge specific capacity: > 125 mAh/g
• First efficiency: > 90%
• Compaction density: > 2.9 g/cm³

Compatibility and use

Suitable for standard cathode slurry processing (mixing with conductive carbon and binder, coating, drying, and calendaring) and for coin-cell or pouch-cell prototyping. Because LNMO operates at high voltage, best results are typically obtained with high-voltage electrolyte chemistries and stabilising additives, depending on the target test protocol.

Typical applications

• High-voltage lithium-ion cathode R&D (≈5 V class)
• Electrolyte and additive screening for oxidative stability
• Fast-charge and high-power performance studies
• EIS-based interfacial diagnostics and degradation studies
