Waste Covid-19 masks will be converted into Lithium-ion batteries

    Millions of masks emitted by the Covid-19 virus will be converted by scientists into lithium-ion batteries. According to a study in 2020, 129 billion protective masks are used every month. Now scientists are planning to use these waste masks in a more useful way.

    A new method has been discovered to make low-cost, efficient and flexible batteries from waste masks. The cleaned waste masks are heated to 140 degrees after immersion in a compound made of graphene. It is then converted into conductive plates, which are the electrodes of the battery. With this method, it was possible to obtain batteries from waste masks.

    Scientists using this method have also reached an energy value of 99.7 Wh / kg. This is a very successful result. However, scientists were able to reach an energy value of 208 Wh / kg by adding calcium-cobalt nanoparticles to the electrodes. Thus, the new method of obtaining batteries from waste masks has been adopted as a successful method.

    It should be noted that there is currently a shortage of batteries in world production. The main reason for this is the gradual depletion of the mines needed to make the battery and the deterioration of relations between the countries. For this reason, analysts say that if we do not find new methods for making batteries, we may face serious problems in the future.
