“…used the FB mode of SECM at fixed ME position (i.e., similar to Figure ) to investigate in situ SEI formation at various negative electrodes with Fc as redox mediator, a mediator that has been used very often in other SECM studies. The SEI formation can be followed by the inhibition of the reduction of Fc + on TiO 2 paste, GC, and graphite composite electrodes in agreement with the results of Tang et al . for GC electrodes.…”

“…DBDMB is a mediator of choice because its functional groups are rather similar to typical solvents such as EC and diethyl carbonate (DEC). In our work, DBDMB showed a much more gradual response rather than the on/off behavior found for other commonly used SECM mediators such as Fc and its derivatives …”

Review of Local In Situ Probing Techniques for the Interfaces of Lithium‐Ion and Lithium–Oxygen Batteries

et al. 2016

Electrodes in lithium‐ion and post‐lithium‐ion batteries are made of composite materials exposing a variety of different surfaces towards the electrolyte. This causes a distribution of current densities and consequently locally different changes of interfaces and bulk materials that might be critical for the performance and durability of secondary batteries. The optimization of local structures of battery materials is hindered by a lack of local techniques that provide in situ reactivity information from such hidden interfaces. A variety of new electrochemical scanning probe techniques are currently adapted to the investigation of battery materials under near‐realistic environmental conditions. The review provides a critical assessment of this development with a particular emphasis on the assessment of the passivating properties of solid–electrolyte interphases, the extension of the concepts to lithium–oxygen cells, and attempts to image ion intercalation reactions.

State‐of‐the‐art scanning probe microscopy (SPM) methods as applied to energy conversion and storage devices, specifically lithium‐ion batteries, are reviewed with an emphasis on the electroactive elements. The unique ability of SPM‐based methods to provide localized information has proven highly valuable for the in‐depth understanding of the fundamental mechanisms, processes, and degradation of lithium‐ion batteries (LIBs). As such, SPM analysis is poised to play a strong role in the competition for new higher performing LIBs, especially given the unprecedented choice and availability of SPM techniques tailored to provide physical and chemical information at the nanoscale.

Review of Recent Development of In Situ/Operando Characterization Techniques for Lithium Battery Research

et al. 2019

The increasing demands of energy storage require the significant improvement of current Li-ion battery electrode materials and the development of advanced electrode materials. Thus, it is necessary to gain an in-depth understanding of the reaction processes, degradation mechanism, and thermal decomposition mechanisms of electrode materials under realistic operation conditions. This understanding can be obtained by in situ/operando characterization techniques that provide information on the structure evolution, redox mechanism, solid-electrolyte interphase (SEI) formation, side reactions and Li-ion transport properties under operating conditions. Here, the recent developments in the in situ/operando techniques employed for the investigation of the structural stability, dynamic properties, chemical environment changes and morphological evolution during electrochemical processes are described and summarized in detail. The experimental approaches reviewed in this paper include X-ray, electron, neutron, optical, and scanning probes. Each advanced technique has unique capabilities to study specific properties of electrode materials within specific limitations. The experimental methods and operating principles, especially the in situ cell designs, are described in detail. To illustrate the applicability and uniqueness of each technique, representative studies making use of the in situ/operando techniques are discussed and summarized. Finally, the major current challenges and future opportunities of the in situ/operando techniques are discussed. Several important battery challenges are likely to benefit from these in situ/operando techniques, including the inhomogeneous reactions of This article is protected by copyright.
