General description

Lithium bis(oxalato)borate (LiBOB) is a class of electrolytic materials that can be used in the fabrication of lithium-ion batteries. Lithium-ion batteries consist of anode, cathode, and electrolyte with a charge-discharge cycle. These materials enable the formation of greener and sustainable batteries for electrical energy storage.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

Application

LiBOB is a novel boron based Li salt electrolyte material for Li ion batteries. It is environmentally friendly with good film forming property and high thermal stability and is compatible with a variety of anodes and metal oxide cathode.
LiBOB is a thermally stable electrolyte that can be used to protect graphite-based anode materials in lithium-ion batteries. It shows good electrochemical performance with a discharge capacity retention of ~ 83%.
