Abstract

Disclosed are negative electrodes for all-solid-state batteries, methods of preparing coating slurry, and all-solid-state batteries. The negative electrode includes a negative electrode current collector and a coating layer on the negative electrode current collector. The coating layer includes a carbon-based material and a metal particle. The metal particle includes a lithiophilic metal. An average particle diameter of the metal particle is in a range of ≥ 10 nm to ≤ 200 nm. A standard deviation of a particle diameter of the metal particle is equal to or less than 50% of the average particle diameter.
