通过水热法和溶剂热法选择性地合成了钴的链状结构，并将其作为碱性二次电池的负极材料进行了电化学研究。所得钴样品具有高的放电容量、优异的循环稳定性和良好的倍率性能。此外，硫的引入大大改善了材料的电化学性能。
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.
