Abstract

See full text

Disclosed are a method for processing and recycling an ultrathin lithium foil and a product, which belongs to the field of lithium-ion batteries. According to the disclosure, a liquid-phase thinning agent is adopted to perform a contact reaction with a lithium metal, the fabricated ultrathin lithium foil has a thickness of 20 μm or less, the surface is flat, the thickness can be randomly regulated, and the uniformity is good. The method of the disclosure can also recycle a lithium-containing byproduct generated in the preparation process. When the ultrathin metal lithium foil prepared by the disclosure is used as a metal lithium negative electrode of a lithium battery, the energy density of the battery can be improved, and the battery manufacturing cost is reduced. The ultrathin metal lithium foil can also be used to supplement lithium for other types of electrode materials, thereby a broad application prospect is achieved.
