Compatibility of lithium oxalyldifluoroborate with lithium metal anode in rechargeable batteries

LiODFB, containing the same molecular moieties as those of LiBOB and LiBF4, has the combined advantages of these two Li+ salts. Although LiODFB has shown good electrochemical performance in Li+ ion batteries, few reports have been released about its use in metallic Li rechargeable batteries. This work has demonstrated the preferential feasibility of LiODFB as the Li+ salt for electrolyte in metallic Li rechargeable batteries.155
