Battery developmentlaboratoryHow to optimize the battery
• Testing different Si sources
• Preparing electrodes
• Research on all components in anode (binder, carbon)
• As well as other battery components such as electrolyte, cathode
• Electrochemical testing of cells• Largest lab scale facility in Norway
11
Commercial batterylaboratoryBattery research for end-users
• Strong cooperation with norwegianmaritime industry
• Predicting life time of commercial batterycells and packs
• Evaluation of battery ageing throughexperiments and modelling
12
Future battery market
• Battery boom
• Giga factories
• Battery prices dropping
• New areas opening up with marketdevelopments:• Stationary storage• Recycling/urban mining• 2nd life batteries
Projects and partners
• Most of our projects are funded via Norwegian Research Council calls• EnergiX
• Larger focus on EU-calls • Some direct projects with industry
