Useful:

• Uses: Lithium bis(oxalate)borate is a new and proprietary conductive salt for the use in high performance batteries like lithium batteries, lithium ion batteries and lithium polymer batteries. The new halide-free product may be used instead of traditional fluorinated compounds like LiPF6, LiBF4, Li-triflate, methanides, imides etc. 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.
