New lithium battery ushered in a breakthrough: high efficiency without exploding, charging 500 times

According to foreign media reports, researchers at Washington State University (WSU) in the United States have proposed an ideal material that can replace the negative electrode material at the time, and to a large extent promote the development of lithium batteries, which also brings to the planning of lithium batteries. New breakthrough. During charging and discharging, lithium ions can move back and forth between the two electrodes. At that time, the anode material was mainly a mixture of graphite and copper, but scientists believed that there was still much room for improvement. Scientists pointed out that pure lithium provides the highest energy density among solid materials. If used as an anode, it can double the life of lithium batteries and store more energy. In order to overcome some of the safety issues surrounding the pure lithium metal anode, the research team turned selenium disulfide and two additives together into the cathode of the battery, forming a protective coating on its surface. Actual tests show that this new type of battery can not only be charged 500 times, but also maintain a high efficiency. (This common protective layer hardly changes the morphology of the lithium anode during the cycle, which helps to reduce the growth of lithium dendrites and harmful side-uses.) Now scientists are trying to commercialize these plans, and those Compared with new plans to disrupt lithium batteries, these plans are more likely to end soon.
