尽管石墨烯及其相关材料的应用已经取得了巨大的科学进展，但石墨烯的成本效益和可规模化生产仍然是其商业化的关键。如果这方面不能成功地解决，它最终可能难以广泛使用，例如其同素异形体碳纳米管。如果石墨烯用于批量应用，例如汽车中的能量储存，其中需要大规模和低成本生产活性材料，则石墨烯生产的容易性尤其重要。幸运的是，石墨烯不仅可以从廉价且丰富的来源（石墨）生产，还可以使用多种低成本方法生产。这篇重点综述文章将研究三种有前途的可扩展的石墨烯生产方法，即氧化石墨，液相剥离（LPE）和电化学路线，重点关注它们的最新进展和剩余挑战。对这些路线的看法将主要从工业角度出发，从而突出石墨烯商业化的紧迫问题。还将讨论关于从这种方法生产的石墨烯片的质量或结晶度的一些主要问题以及对最终块状石墨烯材料进行全面评估的重要性。
Although enormous scientific progress has been made in the application of graphene and its related materials, the cost-effective and scalable production of graphene still holds the key to its commercialization. If this aspect cannot be successfully addressed, it may eventually struggle for widespread use, such as has occurred for its allotrope, the carbon nanotubes. Ease of graphene production is especially important if it is to be used in bulk applications such as energy storage in automobiles where the large scale and low cost production of the active materials is required. Fortunately, graphene can be produced not only from a cheap and abundant source (graphite), but also can be produced using a variety of low cost methods. This focus review article will examine three promising, scalable methods of graphene production, namely the graphite oxide, liquid-phase exfoliation (LPE) and electrochemical routes, with focus on their recent progress and remaining challenges. The perspective on these routes will be mainly taken from the industrial viewpoint, thus highlighting the pressing issues for graphene commercialization. Some of the main concerns regarding the quality or crystallinity of the graphene sheet produced from such methods and the importance of a comprehensive evaluation of the final bulk graphene materials will also be discussed.
