Lithium bis(oxalato)borate (LiBOB) was tested as an additive in propylene carbonate (PC)-rich electrolytes that uses LiPF 6 as the conductive solute. At as low as 5% molar LiBOB showed a distinctive additive effect, i.e. , its participation in the initial surface chemistry on graphitic anode surface effectively prevented exfoliation. This property of LiBOB provides an opportunity of formulating PC-rich electrolytes with improvements in rate capabilities and performances at both high and low temperatures, as compared with the electrolytes based on LiPF 6 or LiBOB as the sole electrolyte solute.
