The main limitation of the use of nanotechnology in battery is the cost related to the method used to prepare materials at a nanoscale and to the layout used to avoid aggregates.
Some works are awaited concerning the membrane. The current one used (PVDF) suffers problems regarding its pores: they tend to get blocked. The future membrane will need to have a porosity low enough to avoid short circuits but sufficient to allow diffusion.
A work is needed concerning the managing of the batteries. To increase the lifetime of a battery, it might be possible to design a battery with a high capacity but which capacity is managed as to be not completely used during charge and discharge phase in order to reduce the solicitation of the material.
