Organic batteries – Building in sustainability
31 March 2021
Sustainable energy storage is in great demand. Researchers at Uppsala University have therefore developed an all-organic proton battery that can be charged in a matter of seconds. The battery can be charged and discharged over 500 times without any significant loss of capacity.
Due to the fact that great many of the batteries manufactured today have a major environmental impact, not least due to the mining of the metals used in them, the point of departure for their research has been to develop a battery built from elements commonly found in nature and that can be used to create organic battery materials. Their proton battery is a large stride towards being able to manufacture sustainable organic batteries in future.
Such batteries open up new possibilities when it comes to areas of applications but – perhaps most importantly – they are sustainable because no mining is required to produce the materials, which is a major problem with conventional batteries. Not to mention all of the carbon dioxide emitted during production , says Christian Christian Strietzel, PhD student at the Department of Materials Science and Engineering.
The transition to a fossil-free energy system, in Sweden and globally, is one of the great challenges of our time. For a successful transition to a sustainable energy system, there must be comprehensive research on, first, technology and, second, the behaviour and circumstances of electricity users. At Uppsala University, a lot of research is going on in this area.
