Denmark's National Laboratory for Sustainable Energy, Risø DTU, is to join the race to develop a new kind of lithium ion battery for EVs (electric vehicles) that can improve on current technology, particularly regarding energy density and safety, writes professional journal Ingeniøren (The Engineer).
 
Risø DTU is collaborating with Positive Energies, a Danish company in the EV sector which has joined forces with Taiwan's Amita to produce lithium ion batteries in Denmark for the first time in many years – and is preparing an application for DKK 22m (USD 4.2m) in EU support funding on the basis of its strong competences in electrochemistry, fuel cells, energy storage and materials science.
 
To gain better control over the chemistry of the lithium ion battery, Risø DTU is planning to develop an inorganic electrolyte instead of the polymer and organic electrolytes in use today. They will also work on developing an interface that prevents the anode from reacting with the electrolyte and causing charge capacity and overheating problems.
 
Meanwhile Risø DTU and its partners will be working on ways to improve charging time through the development of new electrode materials that can manage larger currents. If all goes well, the research team hopes to have a demonstration model of a new battery with an inorganic electrolyte and improved electrodes in the next 3-4 years.
