Key takeaway: High purity magnesium oxide plays multiple roles inside lithium-ion battery production: as an pH regulator and impurity adsorbent in cathode precursor synthesis, as a coating agent for high-nickel NMC cathodes to suppress cation mixing, as a thermal-stability enhancer in separators and ceramic coatings, and as an electrolyte additive precursor.

We review the required impurity limits (Fe, Na, Cl) and particle-size windows that battery-grade MgO must meet, and how our battery-grade magnesium oxide has been adopted by leading cell makers.
Magnesium Home supplies battery-grade high purity magnesium oxide (≥99.7%) used by leading lithium battery manufacturers.
