Key Features & Advantages
  • Elite 5C Fast-Charging Transport: Specially synthesized as micro-scale spherical aggregates (D50: 8.05 μm) of primary nano-grains, offering highly dense liquid contact channels that support continuous 5C charging setups seamlessly.
  • Suppressed High-Voltage Outgassing: Advanced surface stabilization layers protect the layered carbon-oxygen grid structures, entirely eliminating transitional outgassing issues under high-voltage fast-charging parameters.
  • Optimized Surface Passivation Matrix: Features exceptionally well-regulated residual compounds (Li2CO3 at 0.22% and LiOH at 0.05%), optimizing ink viscosity and protecting cast binders against premature cross-linking errors.

APPLICATION SCOPE: High-energy high-power active cathode materials designed for fast-charge pouch prototypes, solid-state system interfaces, and advanced electrochemistry studies.
PACKAGING: Hermetically shipped under vacuum conditions in multi-layered aluminum-plastic shielding systems to avoid ambient storage decay.
IMPORTANT NOTICE: Due to the high specific surface outline (9.11 m²/g) of this micro-nano architecture, this substance is hygroscopically active. Keep raw packages sealed and process batches exclusively within dry cleanrooms or high-purity inert glovebox environments to successfully address how to prevent lrmo moisture degradation before thermal processing.

Frequently Asked Technical Questions

Why is ATOMFAIR® 280 mAh/g High Rate LRMO Cathode Powder chosen for rapid-charging scenarios?

ATOMFAIR® 280 mAh/g High Rate LRMO Cathode Powder integrates an advanced micro-nano hierarchical sphere morphology. This architecture provides high surface reaction contact zones (BET: 9.11 m²/g) that handle intense charge-discharge currents up to 5C without experiencing thermal runtime errors.

What is the capacity profile of this lithium rich manganese based oxide material at 1C rates?

When subjected to coin cell verification loops, the powder delivers a superior practical specific capacity exceeding 240.0 mAh/g across a wide 2.0V–4.8V activation window. For tighter 2.7V–4.6V windows, it maintains a robust baseline of over 230.0 mAh/g.

Does this fast charging lrmo battery precursor prevent gassing under high voltage?

Yes, by applying dedicated structural lattice-passivation treatments, the material prevents oxygen outgassing pathways even when operating near intense high-voltage cutoff zones up to 4.8V, successfully safeguarding pouch cell packaging envelopes from swelling.

How do the trace residual surface compounds affect planetary slurry processing?

Soluble surface free lithium residues are tightly restricted to 0.22% wt for Li2CO3 and an elite 0.05% wt for LiOH. This precise composition minimizes viscosity shifts during mixing and holds a stable slurry processing pH baseline between 11 and 12.

How to prevent lrmo moisture degradation reliably within research laboratories?

To completely solve how to prevent lrmo moisture degradation, materials should remain wrapped in their multi-layer aluminum-plastic vacuum seals during warehousing. All unsealing, weight calculation, and battery ink processing operations must be hosted strictly under anhydrous, high-purity inert glovebox environments.

What capacity trade-off should be expected when cycling this LRMO material under a high-rate 4.6V cutoff versus the ultra-high capacity 4.8V window?

Operating at the 2.7–4.6V high-rate window delivers a 0.1C specific discharge capacity >250 mAh/g and a 1.0C capacity >230 mAh/g, whereas the 2.0–4.8V ultra-high capacity window provides >280 mAh/g at 0.1C and >244 mAh/g at 1.0C. Both voltage protocols achieve a first activation efficiency exceeding 90.0%, so the trade-off is roughly 30 mAh/g in specific capacity at 0.1C in exchange for improved cycling stability and reduced structural degradation at the lower cutoff.

What slurry processing constraints arise from the soluble surface alkali content of this LRMO cathode powder?

The material contains 0.22 wt% Li2CO3 and 0.05 wt% LiOH, yielding a slurry pH in the range of 11.0–12.0 at 25°C. This high alkalinity can induce polyvinylidene fluoride (PVDF) dehydrofluorination in NMP-based systems or cause gelation in aqueous processing, requiring the use of pH-stable binders (e.g., PTFE or specialized SBR/CMC blends) and corrosion-resistant current collectors to maintain slurry homogeneity and electrode integrity.

What moisture control measures are required for handling and storing this high-capacity LRMO cathode material?

The as-received powder has a moisture baseline <1000 ppm as determined by Karl Fischer coulometric titration. To prevent surface alkali hydrolysis and preserve electrochemical performance, storage in an argon-filled dry box (dew point < –60°C) or immediate vacuum sealing is necessary, and the material should be opened and processed in a low-humidity environment (<0.1% RH) to avoid exceeding the recommended moisture threshold.

This LRMO cathode material delivers high specific capacity (>280 mAh/g at 0.1C) and supports 5C fast charging due to its nanostructured spherical secondary particle design. However, its high operating voltage (up to 4.8V) and alkaline surface chemistry (slurry pH 11–12) impose constraints on electrolyte compatibility and slurry formulation for practical deployment.

Positive

  • High specific discharge capacity: Achieves >280 mAh/g at 0.1C and >244 mAh/g at 1.0C in the 2.0–4.8V window, enabling high-energy-density cell designs.
  • Fast-charging capability: Micro-spherical aggregates (D50 8.05 μm) of primary nano-grains create dense liquid contact channels that support sustained 5C charging without significant impedance buildup.

Trade-offs

  • High voltage requires electrolyte compatibility: The 4.8V upper cutoff demands electrolytes with oxidative stability above 4.8V to prevent decomposition and gas evolution during cycling.
  • Alkaline surface chemistry needs slurry optimization: Soluble Li2CO3 (0.22 wt%) and LiOH (0.05 wt%) produce a slurry pH of 11–12, which may cause gelation with PVDF binders or require neutralization steps and solvent adjustments.
