Researchers at the University of Queensland in Australia have developed a new type of nanocoating that can extend the life of lithium batteries and reduce the environmental hazards of spent batteries. A related paper has been published in Nature Communications.

Wang Lianzhou, a professor at the School of Chemical Engineering at the University of Queensland who led the research, told reporters that they "added" a new atomic-thick coating to the positive electrode of the lithium battery. Nickel and magnesium materials were added to this nano-coating, which was extremely strong. It is durable, and nickel and magnesium are less expensive and release less toxic substances. The new coating has strong adhesion and can firmly adhere to the positive electrode of the battery, preventing the battery material from decomposing over time, which can greatly extend the battery life. The lithium battery(neware battery test equipment tested) treated in this way can still maintain stable performance after more than 1,000 times of charge and discharge, which is more than double the charge and discharge times of the original battery.

Prof.Wang Lianzhou said that under the dual pressures 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 believes that this new technology is expected to have wider applications in consumer electronics, electric vehicles and energy storage, and hopes that this technology can be produced on an industrial scale within two or three years.
