Key Points

To develop a battery that eliminates the need for transition metal ions and organic solvents while maintaining energy density.
Developed a dual-graphite battery system using an innovative chemistry without transition metals or solvents.
Conducted experiments to measure energy density and recycling potential of the new battery design.
Achieved comparable energy density to conventional batteries without harmful components.
Demonstrated improved sustainability and easier recycling options for the new battery system.

Abstract

Conventional grid-scale energy-dense batteries are reliant on transition metal ions, volatile and flammable organic solvents, and are not sustainable or easy to recycle. Here, we present a new battery chemistry...
