Dear Hamdah,

This article dealing with Li-ion batteries, not Li-air or Li-O2

see link below maybe help you

At last, I can find exact name of the article "A stable cathode for the aprotic Li–O2 battery"  http://www.nature.com/doifinder/10.1038/nmat3737

"Concerning the choice

of anode, to avoid any possible contamination from reactions on

cycling that might occur between a Li metal anode and DMSO or

TEGDME and to avoid reaction between Li and O2 in the electrolyte,

we have, as in previous studies, employed partially charged

Li1􀀀xFePO4 as the anode22,25,27"
