LiBOB was synthesized by an improved solid-state method. H2C2O42H2O was dehydrated to get anhydrous H2C2O4, and H2C2O42H2O was mortared with LiOHH2O. The mixture of H2C2O4 and LiOHH2O was preheated at 60 ℃ for 2 h before adding H3BO3 in several times to be mortared. In vacuum dryer, the mixture of the three starting materials was preheated in two steps: at 70 ℃ for 6 h and then at 100 ℃ for 3 h.

LiBOB was synthesized by an improved solid-state method. H2C2O4·2H2O was dehydrated to get anhydrous H2C2O4, and H2C2O4·2H2O was mortared with LiOH·H2O. The mixture of H2C2O4 and LiOH·H2O was preheated at 60 ℃ for 2 h before adding H3BO3 in several times to be mortared. In vacuum dryer, the mixture of the three starting materials was preheated in two steps: at 70 ℃ for 6 h and then at 100 ℃ for 3 h.
