Dimethyl Carbonate Battery Grade (DMC)
CAS Number: 616-38-6
Battery-grade dimethyl carbonate (DMC) is a low-viscosity, low-boiling co-solvent that reduces electrolyte viscosity and improves ionic mobility in lithium-ion cells. Used widely in EC/DMC binary and EC/DMC/EMC ternary electrolyte systems, it provides excellent compatibility with LiPF6 at battery-grade purity.
Technical Specifications

Applications
- EC/DMC binary electrolyte (1:1 v/v) for standard Li-ion cells
- EC/DMC/EMC ternary electrolyte base solvent
- Low-viscosity co-solvent for high-power batteries
- Electrolyte solvent for NMC and LFP cathode systems
- Synthetic intermediate for carbonate solvents
Key Features
- Low viscosity (0.59 cP at 25°C) improves rate capability and low-temperature performance
- Purity ≥99.95% with acid ≤5 ppm prevents corrosion of aluminum current collectors
- Low boiling point (90°C) assists in rapid cell drying/electrolyte filling processes
- Green solvent derived from CO2-based synthesis routes available on request
