a The ultrafast discharge of the 3DOP LiMnO2 cathode. b Schematic illustration of the Li ion microbattery containing a 3DOM LiMnO2 cathode and a 3DOP NiSn alloy anode with the top–down scanning electron microscopic (SEM) image of the interdigitated electrodes. Scale bar, 500 mm. c SEM cross-section of the interdigitated electrodes. Scale bars, 50 and 1 mm in the insets. d Current and voltage profiles of the microbattery that is controlled by a single-pole-double-throw (SPDT) relay to periodically power a red light-emitting diode for 10 s and is charged with two AA batteries for 5 min (modified from ref. 96, Copyright permission from Nature Publishing Group)
