In this talk, I will present development of nanostructured Si-C composite Li-ion anodes and P-C composite Na-ion anodes, both of which are composed of nanoscale building blocks and carbon conductive network. The effect of nanoscale building blocks of the active materials and carbon nanostructures are studied on the electrochemical performance. New functional cross-linking polymer binder for the anode materials will be also studied for improving efficiency and cycling stability of the anodes. The stable Si anodes have also been demonstrated to fabricate new hybrid Li-ion capacitors with both high power and energy density to illustrate new application of the anode materials.
