Tris (pentafluorophenyl) borane-containing electrolytes for electrochemical reversibility of lithium peroxide-based electrodes in lithium–oxygen batteries
Tris (pentafluorophenyl) borane (TPFPB) is evaluated as an additive for improving
electrochemical performance of lithium peroxide (Li2O2)-based electrodes. It is found that
TPFPB significantly reduced the charge potential of Li2O2-based electrodes during the first
charge process and improved reversible capacity during cycling without adding air (or O2) to
the cell. To confirm the effect of TPFPB on electrolyte decomposition, the surface chemistry
of Li2O2-based electrodes cycled in electrolytes with and without TPFPB was investigated.
