Electrolyte Design and Interface Engineering toward Safer Energy Storage

Dear Colleagues,

It is widely acknowledged that lithium-ion batteries (LIBs) have had huge success in past decades. However, their safety concerns and insufficient energy density have significantly stymied their wide application in large-scale energy storage systems, such as electric vehicles and grid energy storage. Nowadays, developing safe electrolytes, such as solid-state electrolytes, aqueous electrolytes, non-flammable electrolytes, has been regarded as an effective solution to realize high-safety batteries. Meanwhile, the rational interface design against advanced electrode materials, particularly high-voltage cathodes and high-capacity anodes, can achieve excellent electrochemical performance. Therefore, with great advances in both electrolytes and interface design, next-generation energy storage technologies with both high energy density and great safety are expected.

This Special Issue on “Electrolyte Design and Interface Engineering toward Safer Energy Storage” is dedicated to reporting the latest advances in (but not limited to) solid-state electrolytes, aqueous electrolytes, non-flammable liquid electrolytes, as well as their interface engineering toward realizing excellent electrochemical performance. All the original research articles, reviews and perspectives that are closely related to this theme are most welcome.
