Product IntroductionSodium tetrafluoroborate is the fluoroborate sodium salt used in comparative electrolyte studies and in projects that want a compact alternative to the more common imide salts. The 100 g and 250 g options make it feel like a true supply page, which is a good fit for a salt that is often used as a reference material or alternate electrolyte candidate. |

Sodium tetrafluoroborate is a hygroscopic powder that must be stored in a dry, inert atmosphere to prevent moisture absorption and degradation. Personal protective equipment including gloves and safety goggles should be worn during handling to avoid skin and eye contact.
- Storage Environment: Store the compound in a tightly sealed container within a glovebox or desiccator to maintain anhydrous conditions.
- Handling Procedure: Weigh and transfer the powder in a dry, inert environment to avoid moisture uptake and preserve purity.
- Engineering Controls: Use fume hood or local exhaust ventilation when handling to minimize inhalation of airborne dust particles.
- Chemical Incompatibility: Avoid contact with strong acids or bases without prior assessment due to risk of hydrogen fluoride liberation.
- Contamination Prevention: Keep the container closed when not in use to prevent ingress of moisture and airborne contaminants.
How does the 99.9% purity of NaBF4 affect electrolyte performance in sodium-ion battery cycling tests?
The 99.9% purity level minimizes trace metal impurities that can catalyze solvent decomposition and SEI instability, thereby supporting more consistent cycling performance and reduced parasitic side reactions. While exact electrochemical data is not provided, battery-grade purity is essential for reproducible testing in sodium-ion electrolyte formulations.
Can NaBF4 be substituted directly for NaPF6 in standard sodium-ion battery electrolyte recipes?
Direct substitution is not recommended without validation because NaBF4 and NaPF6 differ in ionic conductivity, solubility in carbonate solvents, and electrochemical stability windows. The product is explicitly described as an electrolyte additive for electrochemical engineering, implying it is optimized for blending rather than drop-in replacement.
What are the critical storage precautions to prevent NaBF4 hydrolysis and degradation?
NaBF4 must be stored in a completely dry environment because it is water-soluble and will hydrolyze upon moisture exposure. The compound does not corrode glass when dry, making sealed glass containers with a desiccant suitable; however, the product description also notes that it decomposes upon heating and with sulfuric acid, so elevated temperatures and acids should be avoided.
This battery-grade NaBF4 (99.9% purity) offers well-characterized thermal stability up to 384 °C and excellent aqueous solubility, making it suitable for electrochemical and metal-refining applications; however, its gradual thermal decomposition and irritant hazard profile require controlled handling and appropriate personal protective equipment.
Positive
- Battery-grade high purity (99.9%): The 99.9% purity level meets stringent requirements for battery electrolyte additive and electrochemical research, minimizing parasitic side reactions.
- High thermal stability: With a melting point of 384 °C, the compound remains thermally stable under typical processing conditions, enabling use in moderate-temperature electrochemical and metallurgical processes.
Trade-offs
- Decomposition under heating or acid: NaBF4 gradually decomposes upon heating and in the presence of sulfuric acid, necessitating controlled thermal conditions and avoidance of strong acids during handling or formulation.
- Irritant and ingestion hazard: The material may cause skin and eye irritation and is harmful if ingested, requiring standard laboratory PPE (gloves, eye protection) and safe storage practices.
