Cu2ZnSnS4‐Based Electrode as an Improvement Strategy for Lithium Rechargeable Batteries: A Status Review

Cu2ZnSnS4 (CZTS) is seen as a microstructure electrode due to its high energy density when applied in lithium rechargeable batteries such as lithium-ion batteries (LIB) and lithium sulfur batteries (LSB). This review provides a systematic observation to evaluate the CZTS electrode capabilities from the perspective of electrode composition and its performance in lithium rechargeable batteries. This review starts by focusing on state-of-art lithium rechargeable batteries using common sulfur/sulfide-based materials reported from literature. The relation between the LSB performance with the active materials - sulfur, binder, solvents, electrolytes, and conducting additive used for lithium sulfide (Li2S) formation required for charge transfer properties is discussed critically. The following section discusses the current progress on CZTS-based electrode in lithium rechargeable batteries and it is found that the highest capacity obtained with improved interfacial compatibility is 1802 mAh g1 by hydrothermal techniques using 1 M LiPF6 in EC/EMC/DMC electrolyte. These properties have made sulfide component in CZTS structure as a great substitute to conventional sulfur/sulfide-based active materials. Therefore, CZTS has become a promising and huge potential electrode in lithium rechargeable batteries.
