"attaching electron-withdrawing groups to the molecular scaffold... increase electric potential... At 1 V, output voltage achieved was 20% higher than in next-best materials... gel-like electrolyte which was adapted to the sulfonamide cathode material and enabled flexible construction. This malleable battery pack retained capacity over 600 charge/discharge cycles... easy to manufacture, stable under standard environmental conditions, and virtually insoluble in water"
