In situTEM oxidation of Li₂O₂particles. (a) Schematic illustration of thein situTEM microbattery superimposed over a low magnification TEM image of a solid electrolyte-coated Si nanowire contacting a single Li₂O₂particle. (b) Higher magnification TEM image of the particles in panel (a), showing a MWCNT bundle contacting two physically separated Li₂O₂particles labeled as particles 1 and 2, respectively. (c)–(g) Oxidation of particles 1 and 2 during application of a 10 V cell potential to the MWCNT/Li₂O₂positive electrode against the Si NW negative electrode.^[35]
