▎ 摘　　要

NOVELTY - An anti-tensile ultra-thin lithium foil has a conductive porous anti-tensile layer formed using inorganic fiber material. The conductive porous anti-tensile layer has pore size of 1 nm to 200 microns and porosity of 10-85%. A discontinuous metal lithium material is located in pores of the conductive porous anti-tensile layer. The discontinuous metal lithium material is dispersed in the pores of the conductive porous anti-tensile layer. A surface protective layer is located on the conductive porous anti-tensile layer. USE - Anti-tensile ultra-thin lithium foil. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the lithium foil, which involves: (A) mixing inorganic fiber material, bonding agent, pore-forming agent and optionally inorganic filler to prepare slurry; (B) coating the slurry; (C) carrying out high-temperature carbonization treatment at 300-3000 degrees C to form conductive porous anti-tensile layer; (D) modifying inorganic fiber material by vapor deposition, magnetron sputtering, electroplating, atomic doping and/or atomic etching; (E) attaching metal lithium material to pores of the porous anti-tensile layer to form discontinuous metal lithium material; (F) dispersing discontinuous metal lithium material in pores of porous anti-tensile layer in the form of discrete metal lithium material; and (G) optionally applying surface protective layer on the porous anti-tensile layer.
