Towards 3D-lithium ion microbatteries based on silicon/graphite blend anodes using a dispenser printing technique

Silicon/carbon–graphite blend slurries designed for 3D-dispenser printed lithium ion microbatteries systematically characterized by rheological and electrochemical methods.

AC parallel local oxidation of silicon

Here, we present a suitable advancement of parallel local oxidation nanolithography, demonstrating its feasibility in alternate current mode (AC-PLON). For demonstration, we fabricated model structures consisting of an array of parallel nanostripes of electrochemical SiO _x with a controlled roughness. Besides, we proved the repeatability of AC-PLON and its integrability with conventional parallel local oxidation nanolithography.

Structural characterization of individual graphene sheets formed by arc discharge and their growth mechanisms

Two types of arc graphene sheets with different morphology and crystal structures are found, and further probed by Raman spectroscopy. Moreover, a new growth mechanism responsible for the difference of arc graphene is proposed.
