Battery activities at IFE
Silicon- based nanoparticle production
• Producing silicon based energy materials
• Free space reactors
• Gas-phase silane polymerization• Understanding the chemistry of silane• Production control• Flexibility in composition• Up-scaling
6
Battery developmentlaboratory
How to optimize the battery
• Testing different material 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
7
Commercial batterytesting
Battery research for end-users
• Strong cooperation with norwegianmaritime industry
• Predicting life time of commercial batterycells and packs
• Evaluation of battery ageing throughexperiments and modelling

Commercial battery testingCommercial battery testing
Life time testing of commercial cells- The BattMarine project
• Cooperation with partners from the maritime industry• Fast growing sector in Norway• Hybrid solutions are necessary
• Safety and life time evaluation of large Li-ion cells and packs
• Develop new measurement techniques
• Risk reduction – physical and economical
16
Li-ion battery ageing
• Calendar life – loss of capacity during storage• Factors: • Temperature• State-of-charge
• Cycle life – loss of capacity due to cycling• Factors:• Temperature• Current – charge and discharge• SoC
• Maximum• Minimum• Cycling window
• Mechanical pressure
17
Recycling and reuse
Recycling and reuse- motivation
• Large need for sustainable handling of used batteries
• Control material flow within Europe• Urban mining through recycling possibilities
• Norwegian industry wants to positionthemself within recycling
• Norway will be one of the first countries to get large volumes of spent EV-batteries goinginto recycling or reuse• 50 % of all new car sales in 2019 was electric• Second largest market worldwide for EVs
19
Possible reuse of Li-ion batteries (2nd life)
• Starting research on safe and sustainable re-use ofbatteries
• Evaluating value, safety and cost-optimized use ofLi-ion batteries at End-of-Life (EOL)
• Open questions:• Economical feasibility (and at what battery cost)• Safety ensured in second life use?• Integration into current energy system
20
BATMAN projectLithium ion BATteries - Norwegian opportunities within sustainable end-of-life MANagement, reuse and new material streams
• Project lead by Eyde Cluster
• Will establish the current Li-ion battery market in Norway, as well control of the material flow analysis
• Will give guidelines to how Norwegian industry should position themselves within battery recycling

Future battery market
• Battery demand estimated to 2000 GWh in 2030
• Need for many new gigafactories
• Battery prices dropping
• New areas opening up with marketdevelopments:• Stationary storage• Recycling/urban mining• 2nd life batteries• Battery production
