Ultralong cobalt sulfide (CoS1.097) nanotube networks are synthesized by a simple one-step solvothermal method without any surfactant or template. A possible formation mechanism for the growth processes is proposed. Owing to hollow structure and large specific area, novel CoS1.097 materials present outstanding electrochemical properties. Electrochemical measurements supercapacitors show that as-prepared ultralong exhibit high capacity, good capacity retention, excellent Coulombic efficiency.
