SUMMARY

Two-dimensional materials take active parts and show outstanding performances in various applications, such as energy storage devices, catalyst, sensors, and transistors due to their unique properties. Regardless, the commercialization of high-quality 2D materials is limited due to critical trade-off between the yield and property control of the product. The cost-effective production of 2D materials while maintaining high-quality on large scale is in need for progressive development in industry. Electrochemical exfoliation is recently introduced technique for facile, environmentally friendly, fast, large-scale production of moderate quality of 2D materials. However, the study of exfoliation mechanism via electrochemistry is nevertheless still lacking. Graphene as a representative 2D material will be first demonstrated for electrochemical exfoliation process to elucidate exfoliation mechanism. The proposed hypothesis will be extended to other 2D materials such as molybdenum disulfide (MoS2) and black phosphorus. Lastly, the charge storage property/performance of electrochemically processed 2D materials with alkali metal anodes based on their structure-property relationship will be evaluated.
