Lithium is now a very important element for the energy domain following the spectacular development of the lithium-ion batteries. However, its characterizationat at the scales of the micrometer and of the nanometer is still challenging. Thus any initiative that develop cooperation between researchers and inform the scientific communittee about the recent advances in this field is welcome.

We can expect that the better characterization of lithium materials and particularly of batteries, will result in a better knowledge of the phenomena taking place in these materials and thus improves the performances of the devices incorporating lithium. Indeed, a better energy efficiency leads to a lower consumption and energy saving. The better knowledge of the behavior of lithium will lead to an expected lifetime of the devices, limiting the planned obsolescence. This will also beneficial for the extraction of lithium from minerals and salts, limiting pollution and saving again energy. These objectives will participate to the transformation of the society, relying less on fossil fuels and more on electricity.
