Brilliant batteries

Batteries come in many shapes, sizes and compositions. They have become so integral to our modern lifestyle – whether powering a mobile phone, or a satellite in orbit – that it’s hard to imagine what life would be like without batteries powering our devices and systems!

Batteries are also playing an increasingly important role in addressing climate change.

Sustainable energy sources (like solar and wind) can be unpredictable and so batteries can be used to store energy, helping to balance the supply and demand for electricity.

How do batteries work?

Building better batteries

Scientists all over the world are working to make batteries that are safer, cheaper and more powerful. One scientific tool that researchers can use to help with battery development is neutron scattering, which is performed at large, specialist facilities across the world. At these facilities, researchers can fire a beam of neutrons (neutral particles) or muons (sub-atomic particles similar to electrons – but heavier!) at a sample and, depending on the interactions, learn about the structures and motions occurring within a material.
