Sensitivity to light elements in the presence of heavier elements makes neutron diffraction an ideal tool to study oxides, hydrides and compounds containing Li. The high penetration also allows various in-situ measurements. With concerns over the future availability of fossil fuels and climate change scientist and engineers from all disciplines are focusing their research on materials for a sustainable future.  Examples of areas where crystallographers are taking up the charge include Li-ion batteries for electric cars, materials for oxygen sensors and solid oxide fuel cells, thermoelectric materials, materials for solar energy.  This is also reflected in the user research that is carried out at the POWGEN diffractometer, the general purpose neutron powder diffraction instrument at the Spallation Neutron Source.  I will show some examples of how structural information obtained from energy storage materials can help us understand their functional properties primarily concentrating on Li-ion batteries.<br/>
