      abstract     = {This work is focused on applying structural concepts and
                      basic chemical principles to model two N-heterocyclic
                      lithium salts, based on trifluoromethyl substituted
                      pyrazolide anions. An easily upscalable preparation method
                      without difficult purification steps was also developed. In
                      a comparative study, the physicochemical properties of the
                      two new lithium salts were investigated, particularly the
                      effect of an additional BF3-group at the nitrogen atom. In
                      comparison to non-substituted lithium pyrazolide, the
                      BF3-addition led to a strong improvement of thermal and
                      electrochemical stability, ionic conductivity, as well as
                      better C-rate and cycling performance. Furthermore, the
                      anodic stability of Al current collectors was investigated
                      and compared to commercial lithium salts, namely LiPF6 and
                      lithium bis((trifluoromethyl)sulfonyl)imide (LiTFSI).
                      Possible mechanisms that lead to the presented improvements
                      are discussed.},
