The improvement of the performance of lithium-ion batteries is a perennial ambition as it raises the possibility of longer-lasting lightweight batteries for a variety of applications from miniature smart devices to electric & hybrid vehicles. A newly developed anode material may replace conventional graphite anodes in next generation vehicle lithium-ion batteries.

The next-generation hybrid anode material using silicon-nanolayer-embedded graphite/carbon has been demonstrated by scientists. It promises an increase in battery capacity, which will inevitably lead to a greater commercialization of electric and hybrid vehicles.

In Korean Government-supported research a team led by Professor Jaephil Cho of the School of Energy and Chemical Engineering at the country’s Ulsan National Institute of Science and Technology, has developed the material. The team said, “This architecture allows compatibility between silicon and natural graphite and addresses the issues of severe side reactions caused by structural failure of crumbled graphite dust and uncombined residue of silicon particles by conventional mechanical milling.” The newly-developed anode material has been developed with an increase in graphite content in composite by 45%. The material promises the manufacture of cheaper higher performance batteries.
