Chinese scientists have developed a self-adaptive interphase in all-solid-state lithium batteries that maintains intimate contact between the lithium metal anode and solid electrolyte without external pressure, a breakthrough that decisively overcomes a major bottleneck toward commercialization.
The researchers from the Institute of Physics of the Chinese Academy of Sciences (CAS), Ningbo Institute of Materials Technology and Engineering of the CAS and Huazhong University of Science and Technology found that the contact between the lithium electrode and sulfide solid electrolyte in all-solid-state lithium batteries is not ideal, with numerous tiny pores and cracks present. These issues not only shorten battery lifespan but may also pose safety risks.
