A two-compartment cell for using soluble benzoquinone derivatives as active materials in lithium secondary batteries

► We designed a two-compartment cell to improve the cycle performance of soluble active materials. ► Some soluble benzoquinone derivatives showed capacities close to the theoretical values. ► Precipitated 2,5-dipropoxy-1,4-benzoquinone cycled by dissolution into the electrolyte. ► High solubility of the active material is preferable for our cell.
