Copper belt for solar energy is an important conductive and thermal conductive raw material for solar energy, mainly including photothermal copper belt and photovoltaic copper belt, which are used to make solar collector plate core, solar cell interconnection bar and junction belt respectively. Photovoltaic modules, inverter and grid-connected switches should be connected by cables, while the module MC4 connector, photovoltaic inverter output terminals, and the connection terminals of grid-connected switches are all using copper cores. The International Copper Association (ICA) research data shows that the average amount of copper used in renewable energy systems is eight to 12 times more than in conventional power generation systems.
Wind power generation mainly uses copper link for the generator, transformer, gearbox and tower tube cable, a wide range of applications. The onshore fan is connected to the substation by the collector cable, and then connected to the electrical and transmission grid. The offshore fan is connected to the offshore booster station through the collector cable, and then connected to the ground voltage transformer station through the distribution cable, and then to the transmission network.
The associated charging pile of new energy vehicles has also become an important area to boost the growth of copper demand. According to the latest data from the International Copper Association and IDTechEx, the average amount of copper used in pure electric passenger vehicles is currently about 83 kilograms, three to four times that of traditional fuel vehicles. In the energy storage system, the lithium battery energy storage system is a product that absorbs, stores and releases the energy in the form of electricity, with the highest efficiency and the most widely used. Copper in energy storage, that is, in lithium batteries, mainly exists in the form of copper foil. According to the data of Gaogong lithium battery, the current thickness of the mainstream lithium copper foil is 6~8 microns, and the estimated amount of lithium copper foil is about 0.63 kg / KWH.
