Abstract
A preparation process for a graphite sheet doped with a recyclable material, a product, and use thereof. The preparation process for the graphite sheet doped with a recyclable material comprises the following steps: S1, processing a recycled activated carbon material to obtain a recycled activated carbon material a; S2, processing a natural expanded graphite material to obtain a natural expanded graphite material b; S3, adding the recycled activated carbon material a to the natural expanded graphite material b and mixing to obtain a graphite composite material; and S4, performing graphitization on the graphite composite material, then calendering same to obtain a graphite sheet. Using the recyclable activated carbon material to prepare the graphite sheet not only achieves an environmentally friendly effect, but also implements the recycling of activated carbon material.
