Performance evaluation of battery-based energy storages for various duties, in terms of power, energy and environmental impact

In this project various storages, with a basis in Li-ion technologies are investigated in terms of their power and energy ability, linked to their environmental impact. The environmental impact is both determined during the user phase as well as during the extraction phase.

In the centre of the storage investigation are the Li-ion battery technologies, with various cathode materials containing both Cobalt and Nickel as well as LFP which is a technology without these heavy rare-earth metals. The power and energy capacity varies with these cathode materials, and by changing the anode material to Lithium titanate oxide a very high power-ability can be obtained.

Furthermore, by designing electrodes with different thicknesses the power versus energy capacity can be altered. Additional storage elements such as supercapacitors and fuel cells, and to a small extent Hydro power are lightly covered in order to bring a completeness around the storage. The requirements on the storage systems are also established, here other activities within the center as well as already ongoing activities at the division of Electric Power Engineering will be utilized the overall aim of this project is to find suitable battery-based storages for various duties in a 100 % fully renewable electric energy system.
