(398ay) Electrical Energy Generation Via Reversible Chemical Doping on Carbon Nanotube Fibers

Chemically modified carbon nanotube fibers enable unique power sources driven entirely by a chemical potential gradient. Electrical current (11.9 μA mg^−1) and potential (525 mV) are reversibly produced by localized acetonitrile doping under ambient conditions. An inverse length-scaling of the maximum power as L^−1.03 that creates specific powers as large as 30.0 kW kg^−1 highlights the potential for microscale energy generation.
