A NEGATIVE ELECTRODE SLURRY CONTAINING AN ADDITIVE FOR A LITHIUM METAL PARTICLE ELECTRODE A NEGATIVE ELECTRODE THEREOF A LITHIUM SECONDARY BATTERY THEREOF AND A METHOD FOR PREPARING THEREOF

摘要

The present invention provides a negative electrode slurry for a lithium secondary battery comprising lithium metal particles, a binder and inorganic particles, a negative electrode for a lithium secondary battery and a lithium secondary battery using the same, and according to the present invention, lithium metal particles are used instead of lithium foil By doing so, the surface area to which lithium ions are absorbed/desorbed increases, thereby improving battery characteristics, and also, SEI film is formed on the surface of lithium metal particles of the negative electrode to effectively inhibit lithium dendrite growth, and to improve capacity characteristics, coulombic efficiency and cycle life. In addition, since the SEI film can be formed on the surface of the negative electrode in a conventional lithium secondary battery manufacturing process without a special additional process, an efficient and simplified process can be applied.
