MSE PRO Lithium-Rich Lithium Iron Oxide (LFO) as Battery Cathode Additives, 100g

Applications:

Due to their low cost and non-toxic nature, lithium iron oxides (LFO) are gaining attention as potential cathode additives for lithium secondary batteries. Li-rich defect anti-fluorite Li₅FeO₄ has emerged as a high-capacity cathode material exhibiting simultaneous anionic and cationic redox without significant oxygen release. LFO can be applied to LFP and ternary cathode materials.

Specifications:

Appearance: Light yellow powder
Particle size: D50 ~5-15um
Chemical Formula: Li₅FeO₄
Theoretical Capacity: 867mAh/g
Package: 100g/bag

Note: The capacity is for reference. This material is for research only.

Reaction Mechanism:

First charging platform (3.5V-4.0V): Li₅FeO₄→2Li⁺+2e^-+Li₃FeO₄

Second charging platform (>4.0V): Li₃FeO₄→2Li⁺+2e^-+LiFeO₂
