Australia develops nano-coating to extend lithium battery life

Sydney, April 3 (Xinhua) — Researchers at the University of Queensland in Australia have developed a new nano-coating that can extend the life of lithium batteries and reduce the environmental damage caused by waste batteries.The paper was published in the journal Nature Communications.Lithium-ion batteries, which have high energy density and high output voltage, are widely used in smartphones, laptops, electric cars and other products, but their cathode material is usually cobalt, which is expensive and toxic, the researchers said.Leading the research institute of chemical engineering at the university of Queensland professor lian-zhou wang told xinhua that they give the positive “add a layer of the lithium battery new atom thick coating, nickel and magnesium has been added to the nano coating material, very strong and durable, and nickel and magnesium cheap, less release of toxic substances.The new coating is strong enough to stick firmly to the positive electrode of the battery, preventing the material from breaking down over time and greatly extending battery life.After this treatment, the lithium battery can still maintain stable performance after more than 1000 times of charge and discharge, which is more than double the number of charge and discharge of the original battery.Wang lianzhou said that under the dual pressure of industrial development and low-carbon environmental protection, it is crucial to develop lithium batteries with lower cost, higher energy density and longer cycle life.He sees broader applications for the new technology in consumer electronics, electric vehicles and energy storage, and hopes it will be available on an industrial scale within two to three years.(after)
