In all-solid-state Li-metal battery (ASSLB) research, interface instability between Li-metal anode (LMA) and inorganic solid-state electrolyte (SSE) is a critical issue. Previous studies focused on interface modification methodology to achieve long-term cycling stability of ASSLB. But strategy establishment without an in-depth understanding of the LMA-SSE interface is limited to a phenomenological solution. In addition, it is frequently overlooked that rechargeable batteries are operated by the behavior of charges inside electric field. Herein, we have effectively overcome the intrinsic vulnerability of SSE to LMA by interface modeling based on energy band theory. The interfacial deterioration, due to undesirable electron transport from LMA to SSE’s surface, is precluded by the self-induced interlayer which forms an interfacial energy barrier. This novel approach is informative tool to reinforce the fundamental understanding of interfacial phenomena in all-solid-state batteries. |
