Description

Lithium Bis(oxalato)borate (LiBOB) is a high-purity, organoborate salt with the molecular formula C₄BLiO₈ and CAS number 244761-29-3. This advanced electrolyte additive is specifically designed for lithium-ion battery applications, offering exceptional thermal stability, electrochemical performance, and enhanced safety characteristics. LiBOB is widely recognized for its ability to form a stable solid electrolyte interphase (SEI) layer on anode surfaces, which improves cycle life and capacity retention in high-voltage battery systems.

Our LiBOB is synthesized under stringent quality control measures to ensure >99% purity (metals basis), making it ideal for research, industrial-scale battery production, and advanced energy storage solutions. It is supplied as a fine white powder, soluble in common organic solvents such as ethylene carbonate (EC), dimethyl carbonate (DMC), and propylene carbonate (PC). Suitable for use in lithium-ion, lithium polymer, and next-generation battery chemistries, this compound complies with industry standards for electrode compatibility and performance optimization.

Lithium Bis(oxalato)borate (LiBOB) is primarily used as an electrolyte additive in lithium-ion batteries to enhance thermal stability and inhibit electrolyte decomposition at high voltages. It effectively suppresses aluminum current collector corrosion and improves SEI formation on graphite anodes. Researchers utilize LiBOB in advanced battery formulations for electric vehicles (EVs) and energy storage systems due to its non-flammable decomposition products. The compound is also investigated for high-temperature battery applications (>60°C) where conventional additives fail.
