LMO-103 Cathode Active Material (LiMn₂O₄) Powder

Overview

LMO (LiMn₂O₄) is a spinel-structured lithium-ion cathode active material widely used for high-power lithium-ion cells. Its 3D lithium diffusion pathways enable fast charge/discharge behaviour, making it a practical choice for power-focused cell designs and for research into spinel cathode stability.

Working mechanism

In LiMn₂O₄, lithium ions reversibly intercalate/deintercalate within the spinel lattice during cycling (typically around the ~4 V class vs Li/Li⁺, depending on electrode design and operating window). This redox activity is primarily associated with manganese, enabling stable voltage output and good rate capability when paired with appropriate electrolytes and conductive networks.

Compatibility & processing

LMO powder is compatible with common cathode manufacturing workflows, including slurry casting (PVDF/NMP or selected water-based binders), calendaring, and assembly into coin cells, pouch cells, or cylindrical prototypes. It pairs well with conductive carbons to maximise power performance.

Typical applications

• High-power lithium-ion cathode studies (rate, pulse performance)
• Electrolyte/additive screening to reduce Mn dissolution
• Coating/doping research for improved cycle life at elevated temperature
• Blend-cathode development and fast-charge prototypes
