Resumen
ABSTRACT: In this research, a comprehensive literature review was conducted over the valorization, use, and circular economy of Zn-C batteries after their useful life. The status of this battery waste in Colombia and Latin America is also presented, as well as some case studies conducted in Medellin involving small business enterprises and research at the university level. The main objective of this work is to develop a polymeric matrix composite material using a conductive resin and battery waste powder comprised of zinc and manganese oxides and carbon, in different proportions as reinforcement, in order to contribute to the environment and innovation of using waste materials as a raw material. This development is complemented with some characterization of raw materials that include scanning electron microscopy, Fourier transform infrared spectroscopy, and x-ray diffraction. Besides, physical, chemical, mechanical, and electrical tests, was conducted in the new material. Results show the high potential of this waste in electronical applications, especially as piezoresistive sensors, showing a good behavior that depends on the amount of battery waste and the electrode configuration of the sensors.
