The term "waste graphite" refers to natural graphite, synthetic graphite, and their products that have lost their original functionality due to breakage, pulverization, performance degradation, or end-of-service life, or虽未完全丧失利用价值但已被弃置, occurring during the production, use, and distribution processes of graphite products used in metallurgy, electrodes, chemical industry, energy storage materials, and other applications. After collection, crushing, sorting, and purification processes, this type of waste graphite can be recycled as a carbon resource and reused in the production of electrode materials, conductive materials, refractory materials, lubricants, or energy storage materials.
