Chainlike structures assembled by Co hierarchitectures: synthesis and electrochemical properties as negative materials for alkaline secondary batteries†
Abstract
Chainlike structures assembled by cobalt hierarchitectures have been selectively synthesized via facile hydrothermal and solvothermal routes and electrochemically investigated as the negative materials for alkaline secondary batteries. The obtained cobalt samples exhibit high discharge capacities, excellent cycle stabilities and favorable rate capabilities. Furthermore, with the introduction of sulfur, the electrochemical properties are greatly improved.
