‘Nanoboxes’ promise to boost energy capacity of lithium-ion batteries

Researchers from Singapore’s Institute of Bioengineering and Nanotechnology (IBN; www.ibn.a-star.edu.sg) and Hydro-Quebec’s Research Institute (Montreal, Canada; www.hydro.qc.ca) have synthetized silicate-based “nanoboxes” that could greatly increase the energy capacity of lithium-ion batteries as compared to that of conventional phosphate-based cathodes. IBN’s…
