Massively manufactured paper-based all-solid-state flexible micro-supercapacitors with sprayable MXene conductive inks

Flexible micro-supercapacitors (FMSCs) are promising candidates for portable and on-chip energy storage due to their miniaturization, lightweight and high-security. Till now, FMSCs still suffer from several limitations, such as complex fabricating process, low areal energy storage, and short cycling lifetime, badly inhibiting its wider on-chip integrated applications. Here, we directly employ an easy-processing spray coating of the Ti3C2Tx MXene...
