Abstract
Proposed is a positive electrode containing a positive electrode active material having a multimodal particle-size distribution to suppress particle crack of the positive electrode active material caused by pressure applied during a positive electrode and cell manufacturing process, thereby exhibiting excellent electrical characteristics. In addition, an all-solid-state battery including the positive electrode is proposed. The positive electrode may include a positive electrode active material formed of a lithium transition metal oxide and having a multimodal particle-size distribution in which particles with relatively small particle diameters have greater particle strength than particles with relatively large particle diameters.
