This proposal describes an approach to establish design rules for novel Li-ion battery electrode materials needed for improving battery charge capacity and effective lifetimes. The work will focus on Si nanowire-based electrodes as they address key limitations in current Li-ion batteries due to their resistance to mechanical degradation and extremely high specific charge capacity. The long term objectives will be determining the structure-mechanical property relationships of Si nanowire-based electrodes and establishing a set of design rules for the synthesis of mechanically optimal electrodes in collaboration with Electrovaya Inc. - a Canadian world leader in Li-ion batteries. Determining the structure-mechanical property relationships of Si nanowire-based electrodes and demonstrating mechanically optimized batteries will directly benefit Canadian industries. It will enable commercially viable nanostructured Li-ion batteries for new products such as long-range electric vehicles as well as extend the battery lifetimes of everyday consumer goods. Canadian battery companies, such as Electrovaya, will benefit directly from the development of nanostructured battery electrodes. Canadian companies will also benefit from new graduates with relevant skills for battery technologies, energy, aerospace, automotive, and electronics industries.
