The current problem

Nowadays, batteries that you find in most rechargeable devices are lithium-ion batteries.

These batteries are currently not sustainable!

The materials that we use to make them use a lot of resources to extract and process them, and they come from very far away, including places where there is war and human exploitation.

That makes the devices employing these batteries also not sustainable.

How do we want to solve it?

We are working towards a future where the energy to power up everything is sustainable and affordable, and that is why our research focuses on:

New battery chemistries


We work with many scientists around the world to discover new types of battery chemistries that avoid critical materials, last for longer and can store more energy.

Some promising new types of batteries include: Sodium-ion batteries, lithium-sulfur batteries, aluminium and zinc batteries.

New materials for batteries


We want to make sure that the materials we use for anodes and cathodes for all future battery chemistries are as sustainable as possible.    

Currently, we focus on the production of materials  from two main feedstocks: biomass and plastic waste.  By employing waste as a resource and by prolonging  the life cycle of energy-intensive materials such as  plastic, we strive to decrease the net CO2 footprint  and costs of our synthesis processes.

Make Your Own Battery workshop

The materials that are used inside the batteries found in your phones, laptops and electric cars are very sensitive to air and water, so they need to be manufactured under very careful conditions to be safe. But these aren’t the only chemicals that can be used to make batteries!

In our Make Your Own Battery workshop, you will be able to build a battery using components that have been made using molecules that can be found in plants and food.

You will find out about the different parts that go into a battery, learn how to put them together, charge it up, and use your battery to light up an LED!
