Battery materials & chemicals are the building blocks of the next generation of energy storage solutions. From powering our smartphones to electric vehicles and grid-scale energy storage, these materials are crucial for the transition to a clean and sustainable energy future.

The choice of chemicals and materials has a significant impact on the performance of a battery:

Energy density: The amount of energy that can be stored per unit weight or volume
Power density: The rate at which a battery can deliver or absorb energy
Cycle life: The number of times a battery can be charged and discharged before its capacity deteriorates significantly
Safety: The risk of fire, explosion, or toxic leaks
Cost: The materials and manufacturing process should be affordable
Sustainability: Sourcing ethically, utilising abundant and environmentally friendly materials, that are easily extracted and then recycled at the end of their lifespan

The development of new battery materials and chemicals is a complex and challenging task, but it is essential for the continued progress of clean energy technologies. By unlocking the potential of these materials, we can create a future powered by safe, reliable, and affordable batteries.
