12th January 2025 – (Beijing) A research team from South China University of Technology has made significant strides in lithium metal battery technology by successfully creating an ideal solid electrolyte interphase on lithium metal anodes. Their findings, published in the esteemed journal Nature, could pave the way for next-generation high-performance batteries.
Led by Yan Keyou, the team developed an interphase characterised by high electronic insulation, exceptional ionic conductivity, and robust chemical stability. These advancements promise to enhance both the performance and safety of lithium metal batteries, which are increasingly viewed as frontrunners in energy storage solutions.
The newly constructed interphase could play a critical role in advancing technologies across various sectors, including new energy vehicles and photovoltaic-storage integration. Lithium metal batteries have the potential to double the energy density of current lithium-ion batteries, yet existing commercial electrolytes have struggled to establish a stable solid electrolyte interphase, limiting their viability.
Utilising monoclinic m-Li2ZrF6 nanoparticles as additives, the researchers successfully formed a solid electrolyte interphase that exhibits outstanding electrochemical properties on lithium metal anodes. This innovative approach allows the batteries to retain 80 percent of their capacity after 3,000 cycles at a 2C charging rate, setting a new benchmark in the field.
The synthesis of m-Li2ZrF6 nanoparticles is both straightforward and scalable, offering a promising solution for the broader adoption of lithium metal battery technology.
