Future Materials Battery Lab
The battery lab’s overarching priority is to study how Lithium-ion (Li-ion) batteries with various chemical compositions behave under different conditions.
A Li-ion battery consists of two electrodes, an anode and a cathode, an electrolyte and a separator separating the electrodes from each other. Li-ion batteries are a rechargeable type of battery where Li-ions move from the negative electrode (the anode) towards the positive electrode (the cathode) when discharging and the opposite direction during charging. The Li-ions move in an electrolyte where the main component is a Li-rich salt.
The battery lab can test different kind of battery cells; like small coin cells, a bit larger pouch cells and in the future cylindrical cells. The cells are placed in a battery testing device where the cells´ “battery capacity”, mAh/g, is measured. The maximum number of cycles or how long a cell withstands charging and discharging while maintaining storage capacity, is also measured.

Elkem also has extensive, complementary characterisation capabilities such as XRD, XRF, FEG-SEM, Particle size and shape, BET, AAS, ICP-MS. The battery lab is located close to Elkem Pilot Plant, an industrial R&D center with core competence in metallurgical high-temperature processes. The combination of a Battery Lab, Pilot Plant facilities and characterisation capabilities makes Elkem Technology/Future Materials well equipped for lab. scale, bench scale and pilot scale experiments.
