• Nanosized sulfur and Co_xS electrocatalyst are electrodeposited on carbon nanotube buckypaper (S/Co_xS/BP) as a binder-free high-performance cathode for lithium–sulfur batteries (LSBs).

• Both electrooxidation of a polysulfide solution (~S₆²⁻) to sulfur and the electrodeposition of highly active Co_xS catalyst substantially increase the current and time efficiency of cathode preparation for LSBs.

在Buckypaper上电沉积的硫和Co x S电催化剂作为Li–S电池的高性能阴极

• 纳米级的硫和Co _x S电催化剂被电沉积在碳纳米管布基纸（S / Co _x S / BP）上，作为锂硫电池（LSB）的无粘合剂高性能阴极。

• 多硫化物溶液（〜S ₆ ^2-）的电氧化成硫，以及高活性Co _x S催化剂的电沉积都大大增加了LSB阴极制备的电流和时间效率。
