As the electric vehicle (EV) revolution takes shape, there is a growing need for high-safety, long-life batteries. However, EV manufacturers are requiring a battery with a higher energy density<\/a> than the current lithium-ion batteries. Because of this, scientists are looking to develop lithium metal batteries that have an anode comprised of lithium. These batteries have a much higher charging capacity than the predominant battery technology of choice, lithium-ion batteries.\u00a0<\/span>\u00a0<\/span><\/p>\n However, lithium metal batteries have safety issues because dendrites, spiky, metallic microstructures, form during charging.\u00a0<\/span>\u00a0<\/span><\/p>\n A team of Chinese researchers aim to solve this problem to ensure that high-safety, long-life lithium metal batteries can be produced for EVs. As part of this goal, the group has designed an electrolyte that prevents the formation of dendrites, offering a solution in the research toward building long-life lithium metal batteries. <\/span>\u00a0<\/span><\/p>\n The findings of the research were published in <\/span>Nano Research<\/a>.\u00a0<\/span><\/i>\u00a0<\/span><\/p>\n Lithium metal anodes have great potential for high energy storage batteries, which are required for EVs. However, they are hindered by uncontrollable lithium dendrite growth. <\/span>\u00a0<\/span><\/p>\n Dendrite growth occurs in lithium metal batteries when lithium ions move and convert to one specific location on the lithium metal surface. This raises significant concerns, resulting in poor cycling efficiency in the battery, which is a severe safety issue.\u00a0<\/span>\u00a0<\/span><\/p>\n By combining the advantages of conventional electrolytes and high-concentration electrolytes, the team was able to tackle dendrite growth. This electrolyte that was created was able to achieve excellent electrochemical performance in lithium metal batteries, whilst also preventing the formation of dendrites. The high-concentration electrolyte holds great promise for use in next-generation battery technology, being able to overcome the issues of conventional electrolytes.\u00a0<\/span>\u00a0<\/span><\/p>\n Chunpeng Yang, a professor at Tianjin University<\/a>, stated: \u201cIts unique structure not only promotes the uniform conversion of ions on the electrode surface, but also ensures the rapid movement of ions in the electrolyte.\u201d<\/span>\u00a0<\/span><\/p>\nConcerns around dendrite growth in lithium metal batteries<\/h3>\n
