    What is graphite lubricant?

    Graphite has a flaky crystal structure with good lubricating properties. It also has good electrical conductivity, thermal conductivity, wear resistance, pressure resistance, temperature resistance (temperature up to 450°C), and chemical stability. Therefore, graphite is widely used in the machinery industry to make various lubricants.

    The development history of graphene materials

    In fact, graphene originally exists in nature, but it is difficult to peel off a single-layer structure. Graphene layers are stacked to form graphite, and 1 mm thick graphite contains about 3 million layers of graphene. A lightly stroked pencil on the paper may leave traces of several layers or even just one layer of graphene.

    Advantages and disadvantages of silicon anode battery materials

    The silicon-based anode has great potential. From the comparison of the performance of different anode materials, the mass/volume ratio of silicon-based anode is huge. The theoretical mass specific capacity of crystalline silicon is about 4200mAh/g, while graphite is only 372 mAh/g, which is about 11 times that of graphite. Even the silicon oxide material has a theoretical mass specific capacity of 2600mAh/g, which is about 7 times that of graphite. From this point of view, silicon-based materials are the most promising anode materials for next-generation lithium-ion batteries.

    Why can pencil lead conduct electricity?

    We know that what kind of properties a substance has is determined by its structure. Diamond does not conduct electricity, so how does graphite conduct electricity? This is about the structure of graphite. As mentioned before, graphite is composed of layers of carbon atoms, and this single layer of carbon atoms is actually what we often hear about "graphene".
