Tiivistelmä
With the world dynamically changing and countries drastically cutting their CO2 emissions, the need for fossil fuel replacement is necessary. Electric vehicles are seen as the alternative means of transport and the future of the automobile industry. This requires enhancements in energy storage. Nanofiber membranes could be the solution to improving lithium-ion battery performance and safety.
The aim of this thesis is to test the nanofiber membrane as a battery separator used in supercapacitors and lithium-ion batteries. This thesis analyzes the current markets of supercapacitors and lithium-ion batteries, as well as other potential markets for the nanofiber membrane to be used in. In addition the future growth potential of the existing markets and the development of new markets is analyzed.
The test results signify that the properties of the PI and PAN nanofiber membranes reached their ideal target values to a high degree. The thickness of the PI membrane was 11.4 µm and 21.6 µm for PAN membrane. The results for porosity for PI and PAN membranes exceed the target value at 79.8% for PI and 81.5% for PAN membrane.
This thesis analyzed the different market entry options. By analyzing the risks and gains involved in the alternatives, it is possible to conclude that partnering as a supplier of nanofiber membrane with a lithium-ion battery manufacturer is the optimal strategy. The world is heading to renewable energy and emission free transportation, hence being involved in the battery business will have numerous opportunities available in the near future.
