Technical Selection Guide

Why LNMO is used for high-voltage cell development

LNMO is a spinel cathode operated near 4.7 V versus lithium, making it a demanding test of electrolyte oxidation stability, cathode-electrolyte interphase formation, and transition-metal control. Its cobalt-free composition and three-dimensional lithium-diffusion pathways make it attractive for high-power and high-voltage research.

Why developers evaluate it

  • High-voltage electrolyte and additive screening
  • LNMO/graphite or LNMO/LTO cell development
  • CEI, gas, and elevated-temperature storage studies

Development considerations

  • Confirm grade-specific particle size and surface condition
  • Match electrode loading and processing to the target cell
  • Use lot documentation and cell-level qualification

How to compare it

LNMO qualification should include residual lithium, particle morphology, surface area, moisture, metal dissolution, and capacity retention at the intended upper cutoff voltage.
