Popis:	Several properties of the electrolyte solution lithium difluoromono(oxalato)borate (LiDFOB) in ethylene carbonate diethylcarbonate (EC/DEC (3:7 mass ratio)) are given, including transference numbers, diffusion coefficients, concentration dependence of cell potentials, and the Haven ratio. The concentration range of the salt covers 0.1 mol·kg–1 to 1.0 mol·kg–1. In comparison to the standard salt LiPF6 currently in use in lithium ion cells LiDFOB has higher transference numbers. However, the Haven ratio related to ion pair formation in an electrolyte indicates a high amount of aggregates in concentrated LiDFOB/EC/DEC (3:7) electrolytes.
