Abstract

Aqueous rechargeable batteries are appealing alternatives for large-scale energy storage. Reversible cycling of high-energy aqueous batteries has been showcased using highly concentrated aqueous electrolytes, which lead to a significantly suppressed water activity and formation of a stable solid-electrolyte interphase (SEI). However, the high salt concentration inevitably raises the cost and compromises the environmental sustainability. Herein, we use layered TiS2 as a model anode to explore the feasibility of cycling aqueous cells in dilute electrolytes. By coupling three-electrode cycling data with online electrochemical mass spectrometry measurements, we depict the potential-dependent gas evolution from the cell in the... (More)

Aqueous rechargeable batteries are appealing alternatives for large-scale energy storage. Reversible cycling of high-energy aqueous batteries has been showcased using highly concentrated aqueous electrolytes, which lead to a significantly suppressed water activity and formation of a stable solid-electrolyte interphase (SEI). However, the high salt concentration inevitably raises the cost and compromises the environmental sustainability. Herein, we use layered TiS2 as a model anode to explore the feasibility of cycling aqueous cells in dilute electrolytes. By coupling three-electrode cycling data with online electrochemical mass spectrometry measurements, we depict the potential-dependent gas evolution from the cell in the absence of a stable SEI. We offer a comprehensive mechanistic understanding of the complex interfacial chemistry in dilute electrolytes, taking into account material reactivity and interfacial compatibility. Design strategies and research directions of layered-type electrodes for sustainable aqueous batteries with dilute electrolytes are recommended, based on the scientific discovery presented in this work.
