The disodium salt of 2,5-dihydroxy-1,4-benzoquinone as anode material for rechargeable sodium ion batteries

Abstract

The disodium salt of 2,5-dihydroxy-1,4-benzoquinone has been prepared and proposed as anode material for rechargeable sodium ion batteries for the first time, showing an average operation voltage of ∼1.2 V, a reversible capacity of ∼265 mA h g⁻¹, a long cycle life (300 cycles), and high rate capability.
