Abstract:

Energy and the environment are important pillars behind the sustainable development of human society. Therefore, the future society requires efficient, economical, green, and safe electrochemical energy storage field to deal with global climate change and energy crisis. Thus, it is crucial to understand the electrochemical interface reaction mechanism to further guide the design of energy storage devices. Time-of-flight secondary ion mass spectrometry (ToF-SIMS), including ex situ and in situ methods, has emerged in recent energy electrochemical fields due to its ultra-high sensitivity, as well as temporal and spatial resolution. This review summarizes the latest developments and applications of ToF-SIMS in recent technologies of energy electrochemistry (e.g., lithium-ion, -sulfur, and lithium-oxygen batteries), with critically considering the technology-assisted revelation of the electrochemical reaction process and further design of better electrochemical energy storage systems. Finally, we also discussed the current challenges and future opportunities of ToF-SIMS, and advocated the widespread use of the technology to guide the design and innovation of future energy storage technologies.
