EXAMPLE

Hydrogen fuel cells

Hydrogen fuel cells work by converting hydrogen and oxygen into water using catalytic electrodes separated by a polymer-membrane electrolyte. Researchers used small angle neutron scattering to investigate variations in water content within the polymer membrane. They discovered that water content in the membrane does not directly correlate with water content in the surrounding channels. This information can be used to design fuel cells with better water management.

EXAMPLE

Lithium-ion batteries

Researchers used high-speed X-ray imaging to study short-circuits in commercial lithium-ion batteries. By analysing the high-speed images, they were able to study the formation of gas pockets and venting, and they could identify consistent failure mechanisms. These new insights can be used to improve battery safety.

EXAMPLE

Electrical circuits

Integrated electrical circuits can sometimes delaminate during manufacture. Researchers used neutron and X-ray reflectometry to characterise the thickness, roughness and density of delaminated and non-delaminated wafers. They identified hydrogen accumulation as being responsible for the lack of adhesion between layers. This knowledge can be used to control (and eliminate) delamination during the manufacturing process.
