Nanostructured carbon-based electrodes: bridging the gap between thin-film lithium-ion batteries and electrochemical capacitors

摘要: The fast evolution of portable electronic devices and micro-electro-mechanical systems (MEMS) requires multi-functional microscale energy sources that have high power, energy, long cycle life, the adaptability to various substrates. Nanostructured thin-film lithium-ion batteries electrochemical capacitors (ECs) are among most promising storage can meet these demands. This perspective presents an overview recent progresses challenges associated with development binder-free, carbon-based nanostructured electrodes prepared from layer-by-layer (LbL) electrostatic assembly, which provide enhanced gravimetric volumetric for ECs power capabilities batteries. Based on findings thin several microns in thickness, LbL-based could also potentially be envisioned electronics, electrified transportation, load-leveling applications if successful scale-up tens or hundreds achieved.
