An exception is the intercalation of ether solvated alkali ions into graphite, a fast and highly reversible process. Here, reversible co\u2010intercalation is shown to also be possible for other layered materials, namely titanium disulfide. Operando X\u2010ray diffraction and dilatometry are used to demonstrate different storage mechanisms for different electrolyte solvents. Diglyme is found to co\u2010intercalate into the TiS 2 leading to a change in the voltage profile and an increase in the interlayer spacing (\u2248150%). This behavior is different compared to other solvents, which expand much less during Na storage (24% for tetrahydrofuran [THF] and for a carbonate mixture). For all solvents, specific capacities (2nd cycle) exceed 250 mAh g \u22121 whereas THF exhibited the best stability after 100 cycles. The solvent co\u2010intercalation is rationalized by density functional theory and linked to the stability of the solvation shells, which is largest for diglyme. Finally, the TiS 2 electrode with diglyme electrolyte is paired with a graphite electrode to realize the first proof\u2010of\u2010concept solvent co\u2010intercalation battery, that is, a battery with two electrodes that both rely on reversible co\u2010intercalation of solvent molecules.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DOI: 10.1002\/aenm.202202377 Authors: Guillermo A.
