Due to the strongπ between graphene sheets-& Pi; Composite use: Graphene can agglomerate to form a layered structure similar to graphite, which in turn affects the insertion and removal of lithium ions. This also proves that pure graphene is not an ideal electrode material for lithium-ion batteries.

Therefore, in the past two years, graphene based nanocomposites, such as graphene/carbon nanotubes, graphene/carbon 60 (C60), graphene/inorganic nanoparticles, and other composite materials, have been widely used in the research of negative electrode materials for lithium-ion batteries. The effective composite between nanoparticles and graphene can effectively prevent the stacking/aggregation of graphene sheets, which is beneficial for the insertion and removal of lithium ions.

1. Current status of international graphene development. At present, countries engaged in graphene industry research internationally include the United Kingdom, the United States, the European Union, South Korea, and Japan, with different development situations in each country.

UK: As the birthplace of graphene, the UK is a global leader in basic research and development of graphene, but there are few graphene companies engaged in commercial development, so it is not its strong suit in graphene applications.

United States: The United States has invested in graphene research earlier, and the industrialization and application process of graphene is relatively fast. Its industrial layout is also diversified, and the industrial chain is relatively complete.
