Tiivistelmä
The ever growing demand of wearables and smart portable devices require power supplies with growing capacities, but being lightweight, economical, environmentally sustainable and with charging times as short as possible. Supercapacitors have attracted the the attention of researchers due to its high power densities, durability, sustainability possibilities and feasibility to be produced by additive manufacturing methods in a cost-effective manner.
This project shows that the production of a working supercapacitor, out of sustainable, recyclable and widely available materials like Poly(vinil) alcohol (PVA), Activated Carbon (AC) and Polylactic acid (PLA), can be done using additive manufacturing methods and with no post-processing needed. Although the performance of the devices in terms of capacity measured by Cyclic Voltammetry (CV) is poorer than those fabricated by other methods (around 1000 times lower in specific capacitance than those reported in [1]), it was achieved to slightly improve the capacity of devices manufactured using similar materials and fabrication methods in a factor of 5.6 ([2]). In summary, this project enlightens the path towards a further development of additive manufactured ecological energetic devices for low power and energy harvesting.
