Just thinking about the crew of people needed to tramp around to change all those batteries is exhausting, and to actually do it would be prohibitively expensive and impractical.

Big Science tools for clean transportation: neutron scattering at ORNL

Green Car Congress

In the case of ORNL’s SNS, the target is mercury. Another major difference is that the intensity of x-ray scattering increases with the electron density of a material; light elements such as hydrogen and lithium thus make very little contribution to scattering. The adsorbed water allows detection by neutrons.
