Lithium-ion chemistry runs hotter and tighter every generation. Nano magnesium oxide answers three needs at once: it coats cathode particles (NCM, LCO) to suppress oxygen release and interfacial side reactions, it neutralizes trace HF in the electrolyte, and it raises the thermal stability of ceramic-coated separators. The result is longer cycle life and better abuse tolerance.

recommended grades

Which Grade to Use

Grade	Key spec	Best for
Nano MgO	20–100 nm, ≥99%	Cathode surface coating, separator ceramic layer, HF scavenging
AR Grade MgO	reagent purity	Electrolyte additive development and lab-scale formulation
High Purity MgO (99.5%)	controlled D50	Electronic ceramics, MLCC substrates and thermal-management fillers

how it performs

Application Engineering

• Cathode coating: 0.1–1 wt% MgO wet-coating passivates the NCM surface — higher capacity retention after 500+ cycles.
• HF scavenging: MgO binds HF formed by LiPF₆ hydrolysis, protecting electrode interfaces during long cycling and high-temperature storage.
• Separator reinforcement: nano MgO in PVDF/PP ceramic layers improves thermal shrinkage resistance and wettability.
• Scale-up ready: same chemistry from 100 g R&D samples to multi-ton supply with fixed impurity profile.
