Lithium Oxalate (Li₂C₂O₄)
Battery precursor • oxy‑salts • Battery
Handling note: Avoid dust generation; oxalates are harmful if
swallowed and may cause irritation. Store cool and dry in sealed
packaging. During calcination, off‑gases are produced—use
appropriate ventilation and abatement.
Purity (battery)
≥ 99.5–99.9%
Molar mass
≈ 101.9 g/mol
Lithium content
≈ 13.6% Li (theoretical)
Loss on drying
≤ 0.2–0.5%
Select grade by impurity limits (Fe/Na/K/Ca/Mg), particle size
distribution for reaction kinetics, and handling preference
(powder vs. microgranular). Specs are representative; shipped
material conforms to the lot COA.

• Battery precursor: co‑precipitation/solid‑state routes;
calcination to Li₂CO₃ for cathode blends.
• Specialty ceramics and reagents. • R&D: tuning PSD/SSA to balance reactivity and handling. |
• 25 kg PE‑lined bags • 25 kg fiber drums • 500–1000 kg
FIBC.
• Small packs for R&D/QC trials. |
• Keep dry, sealed, away from acids; avoid dust.
• Use local exhaust; standard PPE. • During calcination, ensure exhaust treatment for off‑gases. |
Quick process tip: **Theoretical Li₂CO₃ yield ≈ 0.725 kg per 1.0
kg Li₂C₂O₄** (molar basis). Adjust for moisture and assay.
