The idea that "used batteries can not be discarded at will" is deeply rooted in people's hearts When it comes to used batteries, many people think first and foremost that they should be collected and recycled.

Otsu Resources and Geothermal Development Cooperation(GDA) cooperates in the development of exploration data for lithium saltwater extraction equipment and in power generation and direct geothermal use projectsIn a report released today, Canada's Otsu Resources announced that it has signed a joint venture agreement(JV) with GeothermalDevelopmentAssociates(GDA) in Reno, Nevada.

ResistanceThe resistance represents the degree of hindrance of a circuit element to the current transfer, in ohmsSo how does polarization come about?When the battery is discharged, all of these energies can not be fully converted into electrical energy.

The team of Linhaibo of the School of Chemistry of Jilin University took the lead in the international production of high-performance battery-grade carbon materials using rice husks, and used this material to develop cost-effective lead-carbon batteries Its performance has reached the international advanced level.

The mechanism of conversion efficiency loss of crystalline silicon solar cellsThe conversion efficiency of solar cells is limited by light absorption, carrier transport, and carrier collection For monocrystalline Silicon solar cells, the theoretical maximum conversion efficiency is 28 % because the excess energy of the upper band gap is transmitted to the lower band gap photon.

For power batteries, safety and electrical performance are equally important If a high-energy accident such as a collision occurs during the use of an electric vehicle, the lithium-ion battery may be severely deformed and causing serious safety problems such as internal short-circuit of the lithium-ion battery.

The full name of lithium iron phosphate battery is lithium iron phosphate lithium ion battery, which is too long, called lithium iron phosphate battery for short Since its performance is particularly suitable for power applications, the word "power" was added to the name, that is, lithium iron phosphate power battery.

Recently, the people's government of Qinghai province issued the guidance on promoting the sustainable and healthy development of the lithium battery industry in Qinghai province According to the opinions, by 2025, the production scale of lithium carbonate in Qinghai province will reach 170,000 tons/year, and the production capacity of lithium battery cells will reach 60GWh/year.

This year's government work report for the first time put forward "resolutely fight against the blue sky" It has made arrangements to address coal pollution, improve pollution sources, strengthen vehicle exhaust control, and encourage the use of clean energy vehicles.

Professor Guorong Hu, director of the institute of light metals and industrial electrochemistry, school of metallurgy and environment, central south university, pointed out that the development of anode materials has become the key to the large-scale promotion and application of such materials Before 2000, lithium cobalt oxide dominated, accounting for almost 100% of the market.
