Crushing the insolubility of graphite with solid

Using Diels-Alder [4+2] cycloaddition reactions between graphene nanoplatelets (derived from the ball-milling of graphite) and either maleic anhydride or maleimide, O and N atoms were selectively introduced to the edges of graphene nanoplatelets in reasonable yields.

5 shows the Raman spectra of nano-graphite (nGr), which is obtained by ball-milling of large graphite flakes for different durations. The ball-milling procedure breaks the large crystallites into smaller particles and also introduces significant amount of defects, as can be seen from Fig. 1(b). The 2D band changes from a two peak profile to a

current density increased to 500 mA g 1, the FeP/graphite composite could still deliver 134 mA h g, which was more than twice the capacity of the FeP compound alone. Our results suggest that by using a low-energy ball-milling method, a promising FeP/graphite anode material can be synthesized for the sodium battery. Introduction

WO2017105208A1

The invention relates to a process for preparing concentrates of graphene nanoplatelets via the milling of graphite and exfoliants. The novel aspect of this process is characterised by the use of fatty acids and fatty acid esters as exfoliants of the graphene nanoplatelets in the milling system. Both the fatty acids and the fatty acid esters

Graphite functionalization by ball milling with sulfur

In particular, by ball-milling of graphite in the presence of sulfur it was demonstrated that sulfur could edge-selectively functionalize graphene nanoplatelets with a concomitant homogeneous adsorption on and within the graphitic crystallites [14, 15].These literature studies have been conducted by using excess of sulfur with respect to
