Lithium-ion batteries (LIBs) are considered one of the most important solutions for energy storage; however, conventional graphite anodes possess limited specific capacity and rate capability. Bismuth sulfide (Bi2S3) cobalt (Co1−xS) with higher theoretical capacities have emerged as promising alternatives, but they face challenges such significant volume expansion during electrochemical cycling poor electrical conductivity. To tackle these problems, vanadium was doped into Bi2S3 to improve its electronic conductivity; subsequently, a vanadium-doped (V-Bi2S3)@Co1−xS heterojunction structure synthesized via facile hydrothermal method mitigate by closely bonded interface. Moreover, built-in electric field (BEF) created at heterointerfaces can significantly enhance charge transport facilitate reaction kinetics. Additionally, nanofiber morphology V-Bi2S3@Co1−xS further contributed improved performance. As result, V-Bi2S3 electrode exhibited better performance than pure electrode, showed enhanced compared electrode. The displayed high 412.5 mAh g−1 after 2000 cycles 1.0 A coulombic efficiencies ~100%, indicating remarkable long-term stability.

Mn-based materials are considered as promising cathode candidates for aqueous Zn-ion batteries (AZIBs). Herein, Mg2+ incorporation is developed to stabilize MnO, which can promote the reaction kinetics and improve electrochemical performance. In addition, Mg-doped MnO exhibits 80.7 mA h g-1 reversible capacity after 2000 cycles even at a high rate of 2 A g-1.
