“…Metallic Bi has a much higher volume-specific capacity (3800 mAh cm −3 ) compared to graphite anode (756 mAh cm −3 ). Its unique layered structure enables easy intercalation of lithium ions [ 9 , 10 ]. However, low conductivity and large volume expansion (~215%) hinder its practical applications in lithium-ion batteries during charging and discharging processes [ 11 , 12 ].…”

As a candidate anode material for Li-ion batteries, Bi-based materials have attracted extensive attention from researchers due to their high specific capacity, environmental friendliness, and simple synthesis methods. However, Bi-based anode materials are prone to causing large volume changes during charging and discharging processes, and the effect of these changes on lithium storage performance is still unclear. This work introduces that Bi/C nanocomposites are prepared by the Bi-based MOF precursor calcination method, and that the Bi/C nanocomposite maintains a high specific capacity (931.6 mAh g−1) with good multiplicative performance after 100 cycles at a current density of 100 mA g−1. The structural evolution of Bi/C anode material during the first cycle of charging and discharging is investigated using in situ synchrotron radiation SAXS. The SAXS results indicate that the multistage scatterers of Bi/C composite, used as an anode material during the first lithiation, can be classified into mesopores, interspaces, and Bi nanoparticles. The different nanostructure evolutions of three types of Bi nanoparticles were observed. It is believed that this result will help to further understand the complex reaction mechanism of Bi-based anode materials in Li-ion batteries.

“…Metal oxides have gained significant interest as anode materials for LIBs due to their high theoretical specific capacities, which have the potential to deliver higher energy storage capacities compared to those of traditional graphite anodes. Tin oxides (SnO 2 , SnO, Sn 2 O 3 , Sn 3 O 4 ) 7 , 8 tin oxide/iron composite (SnO–Sn 2 Fe), 9 titanium oxide (TiO 2 ), 10 iron oxides (Fe 2 O 3 , Fe 3 O 4 ), 11 nickel oxide (NiO), 12 bismuth oxide (Bi 2 O 3 ), 13 antimony oxides (Sb 2 O 3 , Sb 2 O 4 ), 14 manganese oxides (Mn 2 O 3 , Mn 3 O 4 , MnO 2 ), 15 niobium oxides (Nb 2 O 5 , NbO 2 ), 16 titanium niobium oxide (TNO), 17 tungsten oxide (WO 3 ), 18 etc., have been explored as an anode in LIBs. In addition, perovskite oxides (ABO 3 ) exhibit a range of properties, including a high dielectric constant, elevated polarization, and piezoelectricity, rendering them suitable for various applications, such as high-energy storage, memory, sensors, etc.…”

Graphite, widely adopted as an anode for lithium-ion batteries (LIBs), faces challenges such as an unsustainable supply chain and sluggish rate capabilities. This emphasizes the urgent need to explore alternative anode materials for LIBs, aiming to resolve these challenges and drive the advancement of more efficient and sustainable battery technologies. The present research investigates the potential of lead zirconate titanate (PZT: PbZr 0.53 Ti 0.47 O 3 ) as an anode material for LIBs. Bulk PZT materials were synthesized by using a solid-state reaction, and the electrochemical performance as an anode was examined. A high initial discharge capacity of approximately 686 mAh/g was attained, maintaining a stable capacity of around 161 mAh/g after 200 cycles with diffusioncontrolled intercalation as the primary charge storage mechanism in a PZT anode. These findings suggest that PZT exhibits a promising electrochemical performance, positioning it as a potential alternative anode material for LIBs.

In this article, the review on different modeling approaches used for the dispersion of conductive slurries is presented. It comprises three parts: state‐of‐the‐art dispersion process, physiochemical properties, and different modelling approaches. The first part explains the physical mechanism involved in the mixing process and gives an in‐depth understanding of the applicability of the current techniques available commercially with respect to lab‐scale, pilot plant, and industrially upscaled production of these conductive slurries. The main challenges in slurry formulation prevent the formation of agglomerates and breaking down the preexisting agglomerates. It can be understood by studying the role of process parameters such as mixing time and stirring speed involved in the dispersion process. The second part focusses on the important physiochemical properties such as solid content, particle size distribution, and rheology that influences the electrode performance. The third part focusses on the available modelling approaches based on computational‐fluid‐dynamics‐ and coarse‐grained‐molecular‐dynamics‐based on the need as well as the complexity involved. The important aspects such as accuracy, computational cost, advantages, and limitations for both these approaches are discussed that will help the readers to select an appropriate technique in the modelling paradigm to reduce the energy consumption in the dispersion process.
