Silicon Anode Nanostructure Generates New Potential for Lithium-Ion Batteries

Scientists reveal a new nanostructure that could revolutionize technology in batteries and beyond.

• New research has identified a nanostructure that improves the anode in lithium-ion batteries
• Instead of using graphite for the anode, the researchers turned to silicon: a material that stores more charge but is susceptible to fracturing
• The team made the silicon anode by depositing silicon atoms on top of metallic nanoparticles
• The resulting nanostructure formed arches, increasing the strength and structural integrity of the anode
• Electrochemical tests showed the lithium-ion batteries with the improved silicon anodes had a higher charge capacity and longer lifespan

New research conducted by the Okinawa Institute of Science and Technology Graduate University (OIST) has identified a specific building block that improves the anode in lithium-ion batteries. The unique properties of the structure, which was built using nanoparticle technology, are revealed and explained today (February 5, 2021) in Communications Materials.
