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.

Nonflammable

Yu et al. employed a solid-state reaction using oxalic acid, lithium hydroxide, and boric acid as starting materials for the first time. This was followed by a thermal treatment in the air and a recrystallization process to obtain LiBOB. In addition, LiBOB decomposes into Li2C2O3, B2O3, CO2, and CO at temperatures higher than 300 °C [1].
