Abstract (en)
[origin: WO2020040713A2] The present invention relates to a graphene synthesis method by microfluidization for being used in high energy capacity electrode and/or electrolyte materials in the field of electrochemical energy storage. The method comprises the steps of purchasing expandable graphite of 30 pm thickness and 300 pm diameter, sieving by a sieve with 63 pm mesh size, weighing 1 g of expandable graphite, dispersing it in 400 mL 2-propanol to prepare a suspension, conducting ultrasonic ation for 1 hour at 20 kHz frequency and 40% amplitude, pouring the suspension into the microfluidizer, and performing 4 cycles.
