A discovery from Singapore's Institute of Bioengineering and Nanotechnology (IBN) of A*STAR and Hydro-Quebéc Research Institute (IREQ) in Québec could result in longer-lasting rechargeable batteries for electric vehicles and mobile devices.

Researchers have synthesized silicate-based nanoboxes that could more than double the energy capacity of lithium-ion batteries, compared to conventional phosphate-based cathodes.

“IBN researchers have successfully achieved simultaneous control of the phase purity and nanostructure of Li₂MnSiO₄ for the first time," says Professor Jackie Y. Ying, IBN executive director. “This novel synthetic approach would allow us to move closer to attaining the ultrahigh theoretical capacity of silicate-based cathodes for battery applications."

The research collaboration has been underway since 2011, and researchers plan to further enhance their new cathode materials to enable commercialization of the high capacity lithium-ion batteries.

“There is a great interest in developing new compounds that may increase the energy storage capacity, stability and lifespan compared to conventional lithium phosphate batteries," A*STAR and electricity producer Hydro-Québec say in a statement.
