Sodium Bis(oxalato)borate, often abbreviated as NaBOB, is a sodium salt in which a central boron atom is chelated by two oxalate ligands to form the bis(oxalato)borate anion. In the TCI catalogue, this compound is classified under main-group element chemistry within the Catalysis and Inorganic Chemistry category. In the laboratory, NaBOB is known mainly as a candidate electrolyte salt and additive in sodium-ion battery research. It parallels its lithium analogue, lithium bis(oxalato)borate, which has been studied extensively in lithium-ion battery systems.

Researchers are interested in NaBOB because its anion contains no fluorine, unlike many conventional electrolyte salts based on hexafluorophosphate. This makes it relevant to the search for more environmentally friendly electrolytes. It may also be more stable against the formation of hazardous by-products such as hydrogen fluoride. Researchers also study the role of the bis(oxalato)borate anion in forming interfacial layers on electrode surfaces, which strongly affect cell performance and lifetime. Its boron–oxalate chelate structure also makes it a useful material for studies of boron coordination chemistry, so its value extends beyond electrochemistry.

In Indonesia, energy storage and battery research is growing quickly, driven by the national push toward electric vehicles and renewable energy. Sodium-ion batteries are attracting attention as a possible complement to lithium-ion technology. University chemistry and materials science departments, government research institutes, and industrial R&D laboratories working on electrolyte formulation can use NaBOB in exploratory studies. Inorganic and coordination chemistry groups can also use it as a well-defined boron chelate compound for teaching and research.

Sodium-ion battery electrolyte research: NaBOB is studied as a candidate electrolyte salt, which lets researchers evaluate fluorine-free sodium electrolyte formulations in experimental cells.
Electrolyte additive studies: Researchers add the bis(oxalato)borate anion to electrolytes to study how it changes cell behaviour, following the approach already well documented for its lithium analogue in lithium-ion systems.
Electrode interface investigations: The anion is studied for its role in forming interfacial layers on electrode surfaces, so NaBOB suits experiments on how these surface films form and how they behave.
Fluorine-free electrolyte development: Because its anion contains no fluorine, NaBOB is relevant to work on greener electrolytes that may avoid hazardous by-products such as hydrogen fluoride.
Boron coordination chemistry: Its chelate structure, with two oxalate ligands around a boron centre, makes it a useful model compound for academic studies of boron coordination and main-group chemistry.

Store Sodium Bis(oxalato)borate in its original, tightly closed container, in a cool, dry, well-ventilated place away from moisture and incompatible substances. Electrolyte salts used in battery research usually need careful protection from moisture, so many laboratories handle and store them under a dry inert atmosphere, such as in a glovebox. Always follow the storage conditions on the TCI label. Wear standard personal protective equipment, including safety glasses, gloves, and a lab coat. Avoid creating or breathing in dust, and avoid contact with skin and eyes. Read the TCI Safety Data Sheet before use, and dispose of waste according to local regulations.
