The projected doubling of world energy consumption in the next fifty years requires certain measures to meet this
demand. The ideal energy provider is reliable, efficient, with low emissions source - wind, solar, etc. The low carbon
footprint of renewables is an added benefit, which makes them especially attractive during this era of environmental
consciousness. Unfortunately, the intermittent nature of energy from these renewables is not suitable for the commercial
and residential grid application, unless the power delivery is 24/7, with minimum fluctuation. This requires intervention
of efficient electrical energy storage technology to make power generation from renewable practical.
The progress to higher energy and power density especially for battery technology will push material to the edge of
stability and yet these materials must be rendered safe, stable and with reliable operation throughout their long life. A
major challenge for chemical energy storage is developing the ability to store more energy while maintaining stable
electrode-electrolyte interface. A structural transformation occurs during charge-discharge cycle, accompanied by a
volume change, degrading the microstructure over-time. The need to mitigate this volume and structural change
accompanying charge-discharge cycle necessitates going to nanostructured and multifunctional materials that have the
potential of dramatically enhancing the energy density and power density.
