▎ 摘　　要

NOVELTY - Aramid functional separator comprises an aramid membrane layer (10) and a carbon material (20) bonded to the aramide membrane layer. The carbon material induces a semi-ionic carbon-fluorine bond. A solid electrolyte interphase layer (SEI) is formed in a charging/discharging process. The SEI layer contains lithium fluoride (LiF). A negative electrode is a lithium metal negative electrode. An electrolyte is lithium hexafluoride secondary battery. USE - Functional aramid separator for use in secondary battery (claimed) and high-speed charging of lithium metal anode used in lithium-ion battery system. ADVANTAGE - The functional aramid composite separator has high-capacity and high-speed charging of a lithium metal anode. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a secondary battery, which comprises anode, cathode, electrolyte, and functional aramid separator. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the functional aramid separator. Aramid membrane layer (10) Carbon material (20)
