Lithium-ion battery capacity to get new anode boost

|

Ulsan: A team of researchers claims to have made yet another step towards finding a solution to accelerate the commercialization of silicon anode for lithium-ion batteries. A new approach developed by a team led by Prof Jaephil Cho ( of Energy and Chemical Engineering) could hold the key to greatly improving the performance of commercial lithium-ion batteries.

Prof Cho and his research team have developed a new type anode material that would be used in place of a conventional graphite anode, which they claim will lead to lighter and longer-lasting batteries for everything from personal devices to electric vehicles.

In the study, the research team has demonstrated the feasibility of a next-generation hybrid anode using silicon-nano layer-embedded graphite/carbon. They report that this 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.

This newly-developed anode material has been manufactured with an increase in graphite content in composite by 45%. The research team has also developed new equipment, which is capable of producing 300kg in 6 hours per batch using a small amount of silane gas (SiH4). Such simple procedure ensures a competitive price.

They report that the silicon/graphite composite is mass-producible and it has superior battery performances with industrial electrode density, high areal capacity, and low amounts of binder. The findings of the research have been published in the August issue of the energy journal Nature Energy.
