Advantages and disadvantages of recycled graphite electrode plate

1. Advantages (1) Economic: The cost is only 50% -70% of the original graphite.

(2) Environmental protection and sustainability: reduce graphite mining and solid waste pollution.

(3) Performance standard: meet the needs of low-end industry.

2. Defects (1) Impurity residue: may contain trace metal or ash.

(2) Lower strength: the flexural strength is 10%-20% lower than that of native graphite.

(3) Short life: the service life is slightly shorter under high load environment.

In general, recycled graphite electrode plate is a kind of excellent, environmentally friendly and economic electrode material, which is widely used in various industrial fields. Although its performance is slightly inferior to that of primary graphite, it can still work stably in most non-extreme environments, so it is the preferred solution for sustainable development.
