Tungsten‐Based Materials for Lithium‐Ion Batteries

Abstract

Lithium-ion batteries are widely used as reliable electrochemical energy storage devices due to their high energy density and excellent cycling performance. The search for anode materials with excellent electrochemical performances remains critical to the further development of lithium-ion batteries. Tungsten-based materials are receiving considerable attention as promising anode materials for lithium-ion batteries owing to their high intrinsic density and rich framework diversity. This review describes the advances of exploratory research on tungsten-based materials (tungsten oxide, tungsten sulfide, tungsten diselenide, and their composites) in lithium-ion batteries, including synthesis methods, microstructures, and electrochemical performance. Some personal prospects for the further development of this field are also proposed.

“…With the increasing requirement of consumer electronics and electric vehicles, high-performance and low cost power sources are increased in demand. [1][2][3][4][5] The lithium-sulfur (LiÀ S) batteries are considered as promising next-generation Li-ion batteries owing to its high theoretical specific capacity (1675 mAh g À 1 ). [6][7][8] Unfortunately, some drawbacks originated from sulfur such as lower conductivity, extremely larger volume expansion and high solubility of the polysulfide intermediates in the electrolyte delay its practical applications.…”

[6][7][8][9] Among the numerous transition metal oxides, manganese oxides, such as MnO, [10] MnO 2 , [11] Mn 2 O 3 , [12] and Mn 3 O 4 , [13] are considered ideal candidates for LIB anode materials because of their high theoretical specific capacity, low electromotive force, and environmental benignity. [10][11][12][13] Nevertheless, the intrinsically low conductivity and tremendous volume expansion during the cycling processes are the major obstacles to restrict the large-scale application of manganese oxides-based anode materials.…”

Construction of Ag/WS2 Zero/Two‐Dimensional Hybrid Architectures by Self‐Assembly for High‐Rate Lithium Storage

“…[7] These merits give the WS 2 nanosheets significant advantages as an anode material with higher power and energy densities. [8] However, these WS 2 nanosheets still face two problems to prohibit their practical applications. On the one hand, the WS 2 nanosheets are inclined to restack resulting from high surface free energy, causing an unsatisfactory decay in the electrochemical activity.…”
