- LiMn2O4/graphite batteries using LiF additive were fabricated and their electrochemical performance including discharge, cycling and storage performances were tested and compared with LiF-free LiMnEO4/graphite batteries. The LiMnEO4/graphite battery with LiF added shows better capacity （107.5 mAh/g）, cycling performance （capacity retention ratio of 93% after 100 cycles）, and capacity recovery ratio （98.1%） than the LiF-free battery. The improvement in electrochemical performance of the LiF-added LiMnEO4/graphite battery was due to the fact that LiF can restrain the dissolution of Mn from the spinel LiMn2O4 cathode into the electrolyte, leading to a smaller resistance and polariza- tion.
