6 FAQs about [Waste graphite from photovoltaic cells]
Why is graphite used in photovoltaic power generation?
Due to the excellent properties of carbon [ 4, 5, 6 ], graphite is used to manufacture key upstream equipment in the solar photovoltaic power generation industry chain [ 7, 8, 9 ]. Wu [ 10] pointed out that graphite products are necessary for the development of the photovoltaic industry.
How is Crucible graphite purified for photovoltaic crystal pulling?
In this study, the waste graphite from crucibles used for photovoltaic crystal pulling was first purified by an alkali-acid method, and the experimental parameters were optimized to develop the best purification process. The occurrence state of impurity elements and their decomposition mechanisms during purification were determined.
What is waste graphite used for?
The waste graphite was initially used in the graphite crucible devices used in a monocrystalline silicon crystal drawing furnace. Since the monocrystalline silicon rod was sliced to produce solar cells in a later stage, the purity of the devices used in the furnace was very high.
What impurities are present in waste graphite?
Waste graphite contained various impurity phases, including feldspar, hematite, magnesium oxide, silicon dioxide, and silicon carbide. Analysis showed that feldspar, hematite, silicon dioxide, and other impurities were less homogeneously distributed and attached to impurity phases with silicon carbide as the main body.
Can waste graphite be used to prepare negative electrodes of lithium-ion batteries?
The degree of graphitization of waste graphite was close to that of commercial graphite, indicating that waste graphite may be used to prepare negative electrodes of lithium-ion batteries. Compared with purified graphite, the waste graphite had a lower D peak intensity and, thus, a lower ID / IG ratio.
