Division of Applied Electrochemistry
Electrochemistry is about the interconversion between chemical and electrical energy and a general goal of our research is to make this transformation as energy efficient as possible
Electrochemistry finds its use in areas as energy storage in batteries and fuel cells, and for the production of chemical products and metals in electrolytic processes. It is also used in sensors for chemical analysis as well as for environmental processes as water purification. Many of the challenges that the world is facing today are connected to energy and how to use our resources in the best way, where electrochemical systems will play an increasingly important role.
In the Applied Electrochemistry group at KTH we are about 30 employees working with research and teaching. The research is directed mainly towards electrochemical power sources (lithium-ion batteries, molten carbonate fuel cells, polymer electrolyte fuel cells) and electrolytic processes (polymer electrolyte water electrolysis and chlorate electrolysis). A common theme is mathematical modelling and electrochemical characterisation and of special importance is the development and application of porous electrode theories for battery electrodes and gas diffusion fuel cell electrodes. Studies of mass transport in liquid and polymer electrolytes as well as of electrode kinetics on new electrocatalytic materials are other important activities.
