Compton scattering is one of the promising probe to quantitate of the Li under in-operando condition, since high-energy X-rays which have high penetration power into the materials are used as incident beam and Compton scattered energy spectrum have specific line-shape by the elements. We develop in-operando quantitation method of Li composition in the electrodes by using line-shape (Sparameter) analysis of Compton scattered energy spectrum. In this study, we apply S-parameter analysis to commercial coin cell Li-ion rechargeable battery and obtain the variation of S-parameters during charge/discharge cycle at positive and negative electrodes. By using calibration curves for Li composition in the electrodes, we determine the change of Li composition of positive and negative electrodes through S-parameters, simultaneously.

“…A frequently overlooked problem in LIBs recycling is the question: how to actually get lithium inside the electrodes? Wächter et al [175] provided an innovative solution by ensuring a nanoscopic and uniform carbon coating on a nonconductive metal oxide. Taking advantage of a topotactic solid-state reaction between Li 2 C 2 and V 2 O 5 , the outcome is a few nanometer-thick carbon coating on a lithiated Li x V 2 O y as cathode material.…”

[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.

“…Under heat treatment, an exceptionally uniform, amorphous carbon coating of 15 nm thickness is formed. [ 121 ] Ball milling yields less uniform coatings. It should be noted that the formation of the carbon coating and lithiated phases is very complex, processing through multiple crystalline phases of Li x V 2 O 5 and yielding a variety of product mixtures, not all of which have formed through topotactical intercalation.…”

Intercalation is the fundamental process underlying lithium‐ion batteries and related technologies. While intercalation is electrochemically induced in batteries, it can also be performed with chemical redox agents. In principle, the two processes are equivalent, although there can be differences, such as rate control, side reactions, and charge transfer mechanisms. Chemically induced intercalation can be used where electrochemical methods are impractical or impossible and continues to inspire innovative applications. This chemistry is important in synthesis and pretreatment of intercalation materials, with novel impactful applications emerging that range from lithium recycling to intercalation material‐based redox flow batteries. This review summarizes the use of chemical intercalation and serves as a resource for selecting and optimizing methods specific to material and application. Covering the whole life cycle of intercalation materials: development, synthesis, use, and finally recycling, it can be expected that these reactions will continue to have great impact on the path toward efficient and cheap energy storage.
