“…As a result, a high pH value of the reaction medium may attribute to a high nucleation rate of the oxalate crystals. 29,30 On the other hand, ammonia and the dissolved Mn 2+ , Ni 2+ as well as Co 2+ ions can be available for the formation of [Mn–Ni–Co–(NH 3 ) 6 ] 2+ complexes according to the following reaction ( eqn (1) ), which have been reported in previous works. 26,31 These [Mn–Ni–Co–(NH 3 ) 6 ] 2+ complexes in the solution can be behaved as the insoluble suspended matters, while other Mn 2+ , Ni 2+ and Co 2+ ions in the solution may offer a circumstance with a proper oversaturation degree for the formation of the oxalates ( eqn (2) ).…”

“…Extensive research has been conducted to separate these valuable metallic elements from a solution with a complex composition. The most common methods for extraction of metals can be summarized as chemical precipitation, ,− solvent extraction, − and electrochemical methods. ,, However, it proves challenging to achieve the goal solely by a single method mentioned above due to the diversity of elements in the leachate. Therefore combinations of these methods have been widely adopted for more complete and effective separation of valuable metals …”

Lithium ion batteries have been undergoing rapid development in the global market due to their superior performance. However, the soaring number of lithium ion batteries in the market presents serious disposal challenges at the end of life. Moreover, continuous mining processes are harmful to the environment. From the viewpoint of cleaner production and green chemistry, the efficient recovery and reutilization of spent lithium ion batteries are necessary. In this perspective, the overall process of lithium ion battery recycling, especially the recent advances of hydrometallurgical methods, are summarized, focusing on the leaching, separation, and purification processes. The proper disposal of the waste discharged during the recycling process is proposed, highlighting the mitigation of secondary pollution. In addition, the environmental impact of recycling processes is summarized and thoroughly evaluated by recent life cycle assessment studies, revealing the key role of recycling strategic metal elements toward sustainability in an anthropogenic cycle. Finally, the current challenges in this area are pointed out and perspectives on sustainable approaches, cleaner production, and life cycle assessment are proposed.

“…Thus, the major electrochemical activity is attributed to nickel, while cobalt also can play an active role only at high potentials. However, these materials may suffer from severe capacity and voltage fading upon cycling, which remains the primary barrier for their large-scale commercialization Rapulenyane et al (2018). The layered-to-spinel transition is the leading cause for voltage fading.…”

“…The interatomic potentials represent the potential energy of a collection of interacting atoms as a function of geometric variables, such as distance and angle. They provide the underpinning physical basis for molecular statics, molecular dynamics, and kinetic Monte Carlo simulations of radiation effects in materials Rapulenyane et al (2018). Moreover, the nature of the interatomic bonding and atomic configuration is required before the calculations.…”

Layered transition metal oxides LiMO2 (M= Mn, Ni, Co), exhibit good electrochemical performances and are considered as the prototype materials in the first commercial lithium-ion products. However, their performance as individual cathode has shown drawbacks and ignited interest in transition metal doping to form highly efficient cathodes. Such interest has driven efforts towards development of interatomic potentials to help provide information pertinent to the fundamental aspects of the interaction between atoms and allow accurate modelling of structures. Developing force fields is a tedious process as such cost functions often feature several competing minima. This work aims to obtain interatomic interactions (Ni-Ni, Ni-O, Co-Co and Co-Co) suitable for large scale simulations. The potentials are fitted from the cross-platform, streaming task runner (code-based) GULP. The procedure fits the ionic size (Aij), dispersion parameter (Cij), and the hardness of ions (ρij), according to the Buckingham potentials. The fitted interactions produced structures with lattice constants with a difference of less than 1% in NiO and 8.75% in CoO in comparison to experimental data. Furthermore, they yielded elastic constants with a difference of 0.35% in NiO and 2.01% in CoO. The high temperature molecular dynamic calculations validated the potentials through the melting temperatures. The nanostructures and their radial distribution curves confirmed melting temperatures of 2250K and 2000K in NiO and CoO, respectively. These are in good agreement accord with the experimental melting temperatures of 2206K and 2228K for NiO and CoO, respectively. Moreover, the derived interatomic potential accurately simulates the structural properties and behavior of and LiCoO2. The findings of the current study will enable the implementation of these potentials into LiMO2 (M: Ni, Co and Mn) structures for incorporation as dopants into the LiMnO2 cathode material.
