## Lithium Bis(oxalato)borate (LiBOB, CAS 244761-29-3): Key Functions and Uses
1. **Lithium-Ion Battery Electrolyte Salt**
Lithium Bis(oxalato)borate, commonly known as **LiBOB**, is a fluorine-free lithium salt used in lithium-ion battery electrolyte research and development. It provides lithium ions required for charge transport between the cathode and anode during battery operation.
2. **Electrolyte Additive for Battery Performance**
LiBOB can be used as a primary electrolyte salt or as a functional electrolyte additive. Depending on the formulation, it may help improve electrolyte stability, interfacial compatibility, and electrochemical performance in advanced lithium-ion cells.
3. **Formation of a Protective SEI Film**
One of LiBOB’s most important functions is its ability to form a protective **solid electrolyte interphase (SEI)** on graphite and other electrode surfaces. A stable SEI can reduce unwanted electrolyte decomposition and support more consistent cycling behavior.
4. **Cathode–Electrolyte Interface Stabilization**
LiBOB may also contribute to the formation of a protective cathode–electrolyte interphase. This is particularly relevant to research on high-voltage cathode materials, where interface stability is essential for maintaining capacity, safety, and long-term cell performance.
5. **Thermal Stability and Safety Research**
Compared with some conventional electrolyte salts, LiBOB is valued for its relatively strong thermal stability and fluorine-free composition. It is therefore studied for high-temperature battery applications, thermal-abuse testing, and the development of safer energy-storage systems.
6. **Battery Materials and Electrochemical Research**
CAS 244761-29-3 is widely used in electrolyte screening, coin-cell testing, full-cell development, lithium-metal battery research, graphite-anode studies, and advanced energy-storage materials evaluation. Its actual benefits depend on concentration, solvent system, electrode chemistry, and cell design.
7. **Quality and Procurement Considerations**
When sourcing Lithium Bis(oxalato)borate, buyers should check purity, water content, particle size, battery-grade specifications, packaging, certificate of analysis, and moisture-protection requirements. Useful search terms include **LiBOB, lithium bis(oxalate)borate, CAS 244761-29-3, fluorine-free electrolyte salt, SEI-forming additive, lithium-ion battery electrolyte, and battery research chemical**.
8. **Professional Research and Handling**
LiBOB is intended for professional battery, electrochemical, and materials research. It should be stored and handled according to the supplier’s technical documentation and Safety Data Sheet, particularly because moisture and impurities can affect electrolyte performance. Final suitability should be confirmed through application-specific cell testing and regulatory review.
