Revealing how formation protocols influence the properties of solid-electrolyte interphase (SEI) on Si electrodes is key to developing next generation Li-ion batteries. SEI understanding is, however, limited by low-throughput nature conventional characterisation techniques. Herein, correlative scanning electrochemical cell microscopy (SECCM) and shell-isolated nanoparticles for enhanced Raman spectroscopy (SHINERS) are used combinatorial screening under a broad experimental space (20 sets...
Anatase TiO2 is a promising material for Li-ion (Li+ ) batteries with fast charging capability. However, Li+ (de)intercalation dynamics in remain elusive and reported diffusivities span many orders of magnitude. Here, we develop smart protocol scanning electrochemical cell microscopy (SECCM) situ optical (OM) to enable the high-throughput charge/discharge analysis single nanoparticle clusters. Directly probing active nanoparticles revealed that size ≈50 nm can store over 30 % theoretical...
Dopamine (DA) adsorption and electron-transfer kinetics are strongly sensitive to the structure composition of carbon electrodes. Activation surfaces is a popular method improve DA detection, but role structural features on behavior remains uncertain. Herein, we use scanning electrochemical cell microscopy (SECCM) for local anodization glassy (GC) electrodes in acid media followed by imaging electrochemistry covering both unmodified anodized GC regions same electrode. Electrochemical...
Correlative co-located electrochemical multi-microscopy is transforming our understanding of property-function relationships in electrode materials. By coupling scanning cell microscopy (SECCM) with complementary characterization techniques applied to identical locations a surface, we can now unravel the intricate interplay between various physicochemical properties materials and interfaces their impact on phenomena, high spatial resolution. This review explores recent advances this...
Understanding the solid electrolyte interphase (SEI) formation and (de)lithiation phenomena at silicon (Si) electrodes is key to improving performance lifetime of Si-based lithium-ion batteries. However, these processes remain somewhat elusive, and, in particular, role Si surface termination merits further consideration. Here, scanning electrochemical cell microscopy (SECCM) used a glovebox, followed by secondary ion mass spectrometry (SIMS) identical locations study local behavior...
A lab appropriate to introduce voltammetric techniques and basic electrochemical parameters is described in this work. It suitable study theoretical concepts of electrochemistry an applied way for analytical undergraduate courses. Two electroactive species, hexaammineruthenium dopamine, are used as simple redox systems. Screen-printed electrodes order allow the students focus on avoid tedious instrumentation preparation. The determination species studied with sensitive such...
Screen-printed carbon electrodes (SPCEs) are widely used for electrochemical sensors. However, little is known about their behavior at the microscopic level. In this work, we use voltammetric scanning cell microscopy (SECCM), with dual-channel probes, to determine factors governing response of SPCEs. SECCM cyclic voltammetry (CV) measurements performed directly in hundreds different locations SPCEs, high spatial resolution, using a submicrometer sized probe. Further, localized electrode...

In this work, we highlight advantages Pd-Ni bimetallic electrocatalyst for methanol electrooxidation - convenient choice due low cost Ni combined with observed acceptable catalytic performance Pd. We report synergistic...
Abstract Understanding the formation and properties of solid‐electrolyte interphase (SEI) will enable development enhanced Li‐ion batteries (LiBs) other battery types. Herein, we report scanning electrochemical cell microscopy (SECCM) in a glovebox to characterize SEI on basal surface highly oriented pyrolytic graphite (HOPG) as model system negative LiB electrodes with nonaqueous electrolytes. Different grades HOPG have been studied, which provide range step edge densities surface. The...
Abstract Silicon is a promising negative electrode material for high‐energy‐density Li‐ion batteries (LiBs) but suffers from significant degradation due to the mechanical stress induced by lithiation. Volume expansion and lithiation in Si are strongly anisotropic associated early interfacial transformations linked these phenomena their implications performance remain poorly understood. Here we develop novel correlative electrochemical multi‐microscopy approach study local at stages three...
