AbstractLithium bis(fluorosulfonyl)imide-based liquid electrolytes are promising for realizing high coulombic efficiency and long cycle life in next-generation Li-metal batteries. However, the role of anions in the formation of the solid–electrolyte interphase remains unclear.

AbstractTo meet the increasing lithium demands created by global electrification, a fast, flexible, inexpensive and sustainable mining process is needed, which is yet to be realized. Here we explore an untapped energy source that is inherent in all ion-separation processes to achieve spontaneous Li extraction with net energy production. The driving force comes from the huge concentration difference of counter ions (usually chloride) between the feeding and receiving solutions.
