Bi₂S₃/C nanorods as efficient anode materials for lithium-ion batteries

Abstract

Bi2S3 is a promising negative electrode material for lithium storage owing to its high theoretical capacity. During the Bi2S3/C synthesis process, the carbonization of H3BTC prevents aggregation of Bi2S3 particles, with an average diameter of 60 nm.

Preparation and Electrochemical Performance of CoSe2−MnSe2 for Application in Lithium‐Ion Batteries

“…It can also be seen that in the discharge/charge curves of all electrode materials, the specific capacity of the first discharge is higher than that of the subsequent discharge. It can be attributed to the formation of SEI film, which is similar to the previous reports . In the first cycle, it can be seen that the reduction peaks appears at 1.42 V and 0.35 V due to the reduction of metal ions.…”

“…It can be attributed to the formation of SEI film, which is similar to the previous reports. [36] In the first cycle, it can be seen that the reduction peaks appears at 1.42 V and 0.35 V due to the reduction of metal ions. The broad oxidation peaks at 1.21 V and 1.96 V in the lithium ion extraction can be ascribed to the oxidation of metals, consistent with the CV curve.…”

Bismuth Sulfide–Integrated Carbon Derived from Organic Ligands as a Superior Anode for Sodium Storage

“…In a typical synthesis of Bi 2 S 3 , 0.05 g Bi‐BTC and 0.3 g sublimated sulfur powders were mixed, which was added to a glass tube. The tube was sealed under vacuum condition and subsequently annealed at 400 °C for 4 h in a vacuum ambiance to prevent the formation of Bi 2 O 3 . The brownish product was collected by centrifugation followed by repeated washing with CS 2 for several times to extract excess sulfur and other impurities, then dried at 60 °C overnight.…”

Bi‐Based Electrode Materials for Alkali Metal‐Ion Batteries

“…However, the poor electrical conductivity, huge volume expansion and polysulfides dissolution compromise the cycle performance. To mitigate these difficulties, a series of strategies have been utilized, such as fabricating nanostructured Bi 2 S 3 , [118][119][120] forming hybrid composite with conductive matrix [57][58][59][121][122][123][124][125][126][127][128][129][130][131] and engineering hollow space, [132][133][134][135] etc.…”
