含氟聚合物在锂金属电池中的应用OA

Lithium metal anode is considered to be the"holy grail"in the field of energy storage bat-teries due to its high specific capacity(3 860 mAh/g)and the lowest reduction potential(-3.04 V vs.standard hydrogen electrode),but the large number of dendrites generated on the surface of lithium metal anode during charge and discharge lead to decline in battery Coulombic efficiency and cycling performance.Furthermore,the uncontrollable growth of lithium dendrites easily punctures the sepa-rator,cause battery short circuit,and even battery explosion and other safety problems.Based on the main challenges of lithium metal anode,combined with the application of fluoropolymer in lithium metal batteries in recent years,this review demonstrates the important role of fluoropolymer in lithium metal batteries from the aspects of solid state electrolyte,separator modification layer,binder,artificial solid electrolyte interface(SEI)layer,composite anode,etc.Finally,the future research di-rection and development trend of fluoropolymer in the field of lithium metal are prospected.
