Energy storage capacity and environmental adaptability as the two important elements of energy storage devices towards an intelligent Internet of things era, the two often do not co-existence. The continuous exploration of advanced multifunctional electrodes is of great significance to achieve balance between superior capacity and complex service environment adaptability. Notably, it still remains a great challenge to realize high capacity under extreme complex stress and climate environments. Herein, coralline-like (Ni, Co, Mn) Se nanoarrays were synthesized on highly-conductive 3D-printed wave-structure carbon-rich periodic lattices as multitasking free-standing, binder and current collector-free electrodes towards editable ultrahigh-capacity, complex-stress and all-climate energy storage. As expected, the as-prepared wave-structure electrodes exhibit a combination of editable ultrahigh capacitive performance (5.6-7.8 F cm(-2) at 1 mA cm(-2)), superb mechanical resistance (up to 260 MPa) and wide climate compliance (temperature: from -20 to 85 degrees C; humidity: from 20 to 85% RH). More impressively, such a multipurpose device also demonstrates a record-high areal energy density of 260 mu Wh cm(-2), and an ultralong lifespan even under extreme conditions of 85 degrees C & 85% RH & 3 MPa. This strategy opens up novel avenues to explore various bespoke multifunctional integrated devices and multiscale structural materials for future smart life. (C) 2021 Elsevier Ltd.
