Li5FeO4 (LFO) Cathode Prelithiation Additive for Battery Research

Li₅FeO₄ Cathode Prelithiation Additive

Li₅FeO₄ (LFO), also known as lithium-rich iron oxide, is a sacrificial cathode prelithiation additive for lithium-ion battery research. During the first charge, LFO can provide additional active lithium to help compensate for irreversible lithium loss associated with anode solid-electrolyte-interphase formation. It is suitable for laboratory formulation studies involving lithium iron phosphate (LFP), lithium cobalt oxide (LCO), and other compatible cathode systems.

This material is supplied in research-scale packs for electrode formulation screening, half-cell evaluation, and full-cell prelithiation studies.

Supplier-Reported Typical Data

Reference Coin-Cell Test Conditions

• Charge method: constant current–constant voltage (CCCV)
• Constant-current step: 0.066C
• Constant-voltage cutoff: 0.01C

Handling and Storage

Li₅FeO₄ is sensitive to moisture and carbon dioxide in ambient air. Store tightly sealed in a cool, dry environment and minimize exposure during weighing and slurry preparation. Use dry-room or inert-atmosphere handling when required by the experimental protocol. Confirm compatibility, addition ratio, voltage window, and processing conditions for the intended cell chemistry before use.
