Properties：It is a white crystal or crystalline powder. It dissolves in water and alcoholic solvents, with a high solubility. It has good chemical stability.

Uses：Lithium bis(oxalato)borate (LiBOB) is an electrolyte type lithium battery additive, mainly used in lithium manganate system batteries, because it can significantly inhibit the dissolution of manganese in lithium manganate and ternary manganese doped batteries. LiBOB is a film forming additive for lithium batteries. It can make solid electrolyte interface film (SEI) form a structure rich in boron and oxygen at the positive electrode interface, which significantly slows down the oxidation reaction of electrolyte and the loss of transition metal ions. At the negative interface, it can also promote the SEI film to be boron-rich and oxygen-rich, thereby improving the migration rate of lithium ions and reducing the diffusion energy barrier of lithium ion transmission, so as to improve the ratio performance and specific capacity of the battery, improve the stability of the battery and extend the service life of the battery.

Storage：This product is hygroscopic and should be stored in a sealed container, protected by an inert gas (such as nitrogen or similar). It is recommended to store it in a cool, ventilated, and dry place, with a storage temperature not exceeding 35°C. The shelf life is 6 months.
