Due to its low cost, wide availability, environmental friendliness, and high theoretical capacity, transition metal sulfide has received high interest in the field of secondary batteries. However, abnormal structural changes in these materials cause electrode crushing and limit their actual electrochemical capacity. Here, a simple one-pot polyol reflux method is used to produce a manganese sulfide (MnS) electrode complexed with nitrogen-sulfur co-doped carbon (MnS@NSC) for high-power lithium-ion batteries. These electrodes exhibit a unique spherical particle morphology due to their optimized average particle size (300 ＜x ＜500 nm) and porosity properties. With nanostructured, porous, and heteroatom-doped conductive carbon networks, composite electrodes overcome strong structural changes, providing high practical storage capacity, long-term cycle stability, and excellent velocity performance. |
