“…Over the past few decades, the ever-increasing energy consumption and rapid depletion of fossil fuels have driven extensive research activities on the development of green and costeffective electrochemical energy storagea nd conversion technologies, such as batteries, supercapacitors, and electrocatalysts. [1,2] Undoubtedly,e lectrode materials, as the key component of advanced energy storage/conversion devices, play crucial roles for achieving satisfactory electrochemical performance. [3,4] In this respect, 2D materials with uniquemechanical, electronic, and opticalp roperties,s uch as graphene, transition-metal dichalcogenides (TMDs), layered oxides, and black phosphorus, are one of the central research topics in energy storage.…”

Submicrospherical and Porous Bi2S3 Protected by Nitrogen‐Doped Carbon for Practical Anode Fabrication of Li‐Ion Batteries

“…Various anode materials with higher capacity have been extensively explored in recent years, among which alloy‐type anode materials are the most promising alternatives to graphite owing to their well‐defined and low potential plateaus during the alloying reaction with lithium, which is essential for a battery of steady working voltage In the alloy‐type family, bismuth‐based materials also attracted considerable attentions . In particular, Bi 2 S 3 , based on a mixed conversion and alloying reaction mechanism (Bi 2 S 3 +12Li↔3Li 2 S+2Li 3 Bi), possesses not only high gravimetric capacity (theoretically 625 mAh g −1 ), but also high volumetric capacity (theoretically 4250 mAh cm −3 ), which is two times and five times that of graphite, respectively.…”

Sulfur‐Doped Carbon‐Wrapped Heterogeneous Fe3O4/Fe7S8/C Nanoplates as Stable Anode for Lithium‐Ion Batteries

“…Developing sustainable and efficient environmental friendly energy storage systems and devices are becoming urgent due to the increasing environmental pollutions and energy demand . Lithium‐ion batteries (LIBs) are considered to be promising energy storage devices and have been widely used in portable communication equipment, electric vehicles and military fields because of their high capacity, long lifespan and environmental friendly . However, the energy density of lithium ion battery has meet the bottle‐neck and is largely dependent on the innovation of electrode materials.…”

“…[1][2][3] Lithium-ion batteries (LIBs) are considered to be promising energy storage devices and have been widely used in portable communication equipment, electric vehicles and military fields because of their high capacity, long lifespan and environmental friendly. [4] However, the energy density of lithium ion battery has meet the bottle-neck and is largely dependent on the innovation of electrode materials. The stateof-art graphite anode material owns relatively low theoretical capacity (372 mA h g À 1 ), which cannot meet the needs of higher energy/power densities.…”
