Description
Nano-silicon can be used to produce high-purity polycrystalline silicon and organosilicon polymer materials, and can also replace nano-carbon black or graphite as anode materials for lithium-ion batteries. This dataset includes major raw materials, energy inputs, atmospheric emissions, and waste generated during the production process; however, infrastructure such as manufacturing of production equipment and construction of facilities are not included within the system boundary. The life cycle inventory is compiled from data derived from multiple sources. Nano-silicon is produced using an electrothermal process, which employs electricity as the heat source and carbon as the reducing agent, carried out in a semi-enclosed submerged arc furnace. The main production steps include batching, electric furnace smelting, refining and casting, and product crushing.
Activity Description
