Researchers at the 'National University of Science and Technology MISIS' (NUST MISIS) have created functional batteries by using upcycled facemasks. The used masks go through a process of disinfecting through ultrasound before being used to ensure the safety of the batteries.
As for how the masks are turned into batteries, the researchers dip the masks in a graphene-based ink and heat them up to 140°C, then compress them to form conductive electrodes for use in a battery. These electrodes are then separated using other upcycled masks as an insulating layer. Lastly, the batteries are enclosed in another upcycled casing made out of drug blister packs.
These batteries upcycled from masks deliver 99.7 watt-hours per kilogram, which is nearly as powerful as a standard lithium-ion battery. Mask waste is a large negative side-effect of the pandemic, so finding efficient uses for the waste, such as batteries, is crucial for sustainability and cyclicality.
