▎ 摘　　要

NOVELTY - Primary lithium battery has negative electrode of primary lithium battery is composed of stretch-resistant ultra-thin lithium foil. The stretch-resistant ultra-thin lithium foil includes conductive porous stretch-resistant layer includes conductive porous stretch-resistant layer formed by bonding inorganic fiber material, the porous stretch-resistant layer has a pore size of 1 nanometer to 200 microns, and a porosity of 10-85% and discontinuous metallic lithium material located in the pore of the porous stretch-resistant layer. The discontinuous metallic lithium material is dispersed in the pore of the porous stretch-resistant layer in the form of discrete metallic lithium and optionally located in the surface protection layer on porous stretch-resistant layer. USE - Primary lithium battery. ADVANTAGE - The primary lithium battery has overcomes the problem that the traditional lithium belt cathode has low tensile strength, using thick lithium belt to reduce the energy and lithium resource waste. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the primary lithium battery, which involves using the die-cutting machine to obtain the rolled anti-stretching ultra-thin lithium foil punching sheet as the sheet with a certain size as the cathode, using negative plate and the electrolyte, a diaphragm and a positive electrode obtain a primary lithium battery, or using the negative plate and the solid electrolyte and the positive electrode to obtain a primary lithium battery.
