| Research Abstract |
We focused on superconcentrated organic solutions as a new electrolyte for high-performance lithium-ion batteries. We observed enhanced electrochemical stability at both positive and negative electrodes in superconcentrated organic electrolytes. Using the salt-superconcentrating strategy, we realized reversible operation of graphite negative electrode in various organic solvents without organic carbonate. These findings provide a new guideline for designing a new organic electrolyte and contribute to the development of high-voltage lithium-ion batteries.
