The steel vial was sealed with an elastomer ‘O’ ring seal. The ball milling was performed for 150 h without interrup-tion. The weight ratio of steel ball to graphite powder.
Horizontal high energy planetary ball milling process High pure graphite (99.99 ) sample (denoted as FEED) was taken for planetary ball milling. Fig. 1 shows the schematic design of planetary ball.
In a typical experiment, ball milling was carried out in a planetary ball-mill machine (Pulverisette 6, Fritsch Fig. S1A) in the pre-sence of graphite (5.0 g, Fig. 1A), dry ice (100 g, Fig. 1B) and stainless steel balls (Fig. S1B). Detailed experimental conditions for the ball milling can be found in.
Ball milling is an effective way of producing defective and nanostructured graphite. In this work, the hydrogen storage properties of graphite, ball-milled in a tungsten carbide milling pot under 3 bar hydrogen for various times (0-40 h), were investigated by TGA-Mass Spectrometry, XRD, SEM and laser diffraction particle size analysis.
This method is difficult and costly. Using ball milling to produce graphene from graphite and melamine under simple working conditions has been described, and the composite was examined as supercapacitor electrode material (Xue et al. 2015). Due to its simplicity, eco-friendliness, scalability and low cost, ball milling is the method of choice here.
