“…Fortunately, some progresses on this aspect have been made. [ 157 ] By taking the advantage of microwave‐assisted hydrothermal synthesis, LiFePO 4 nanocrystals with very good electrochemical performance were prepared in pure water without using any organic solvent or surfactants. Moreover, the recycling of valuable Li 2 (SO 4 ) was realized according to the processing route shown in Figure .…”

The sluggish Li‐ion diffusivity in LiFePO4, a famous cathode material, relies heavily on the employment of a broad spectrum of modifications to accelerate the slow kinetics, including size and orientation control, coating with electron‐conducting layer, aliovalent ion doping, and defect control. These strategies are generally implemented by employing the hydrothermal/solvothermal synthesis, as reflected by the hundreds of publications on hydrothermal/solvothermal synthesis in recent years. However, LiFePO4 is far from the level of controllable preparation, due to the lack of the understanding of the relations between the synthesis condition and the nucleation‐and‐growth of LiFePO4. In this paper, the recent progress in controlled hydrothermal/solvothermal synthesis of LiFePO4 is first summarized, before an insight into the relations between the synthesis condition and the nucleation‐and‐growth of LiFePO4 is obtained. Thereafter, a review over surface decoration, lattice substitution, and defect control is provided. Moreover, new research directions and future trends are also discussed.

“…For the consideration of the recycling LiFePO 4 , one has however to keep in mind that the particles have to be coated with carbon for enabling electric conductivity. [152][153][154] Tran et al recently reported on the application of deep eutectic solvents, i.e., eutectic mixture of Lewis or Brönsted acids and bases, for green recycling of LIBs, covering both cathodes based on LiCoO 2 and LiNi x Mn y Co z O 2 . [155] Using a mixture of choline chloride and ethylene glycol in a 1:2 ratio as deep eutectic solvent allowed to extract cobalt from used cathodes at a seemingly low temperature of 135 °C.…”

[1,2] This review summarizes and critically assesses current LIB recycling technologies from a sustainable perspective in order to derive whether current solutions can be referred as green technologies. The structure of the present review contains an introduction to the historical evolution of Li-based storage devices and recent issues in the supply chain of critical raw materials (CRMs) (Section 1), before focusing on chemical recycling strategies. This section shall deliver the mandatory input parameters for the subsequent analysis of LIBs recycling technologies to the reader. The review's primary focus is on the chemical aspects of LIBs recycling rather than technological aspects of recycling, and we refer readers to recently published reviews for the latter. [3,4] The second section encompasses conventional recycling methods and includes besides published articles in peer-reviewed journal also recycling solutions that were patented. Given the high economic importance of recycling business models, it is not surprising that many prospective solutions are only available in form of patent applications rather than being published in scientific journals. The third section expands recycling to sustainable recycling that ensures both a reduced toxicity and a close to CO 2 -neutral process. The fourth section elucidates the impact of using renewable materials on the chemistry of recycling processes of LIBs. The fifth section spans the connection of LIBs recycling to future Li-based energy storage devices. The final section concludes with an outlook to the future of sustainable recycling. The review considers only previously reported work that either i) describes the experimental details or ii) offers a reference to patents that describe the experimental procedure. Although we do not neglect the importance of published reports that may not fulfill the abovementioned requirements, we strongly believe that the latter are necessary for the development of sustainable recycling process ensuring reproducibility.

Over the past decades, nanomaterials have been proven to have superior properties, because of their unique structural features differentiating from atoms and bulk materials, and their large-scale production for commercial applications has been receiving increased attention. However, the costs and wastes generated during the synthesis process get scant attention, even in the laboratories. In this Perspective, we review and emphasize the significance of recycling valuable elements from the chemical synthesis processes of nanomaterials. Recent advances, including both physical and chemical methods, for recycling valuable by-products during the synthesis process are summarized, and future directions in this research area are proposed and highlighted as well.
