10,000 charge and discharge cycles: The university develops sulfur battery technology

Core Research Institute December 15 news, a few days ago, according to media reports, researchers at the University of Adelaide in Australia in the progress of sulfur battery technology, the university's energy and catalytic materials director Director Professor Qiao Shizhang said, "Researchers designed a high-efficiency electrode material to catalyze battery reactions and improve the durability of metal sulfur batteries." ”

He said that for the next generation of energy storage devices with lower cost and higher energy density, metal sulfur batteries are one of the main options. However, the cyclic durability of such batteries is generally poor, and the number of times it can be recharged is limited. In contrast, this new sulfur metal battery can charge and discharge at least 10,000 times. This battery may store at least twice as much energy in terms of weight as the current generation of lithium-ion batteries. Sodium-sulfur batteries are several times cheaper than lithium-ion batteries and are the mainstream power supply for electric vehicles and electronic products such as mobile phones and laptops. The materials used in sodium sulfur are generally environmentally friendly.

"Our basic research advances will inspire sound design of high-performance metal-sulfur batteries and facilitate the development of large-scale energy storage technologies," professor Qiao said, "and these findings are expected to make metal-sulfur batteries a technically and economically viable approach in the energy storage industry within 5 to 10 years." "The findings of Professor Qiao and his team, published in the journal Nature Communications, provide an important opportunity for metal-sulfur batteries as a cost-effective alternative to existing applications to ensure energy safety and reliability and help reduce energy costs."
