The management and recycling of waste which contains critical metals has become a high
priority. Improper management of this waste leads to adverse effects for both the …

Primary zinc-air batteries are extensively used in medical, military, and telecommunication
applications. The structure of zinc-air batteries consists of a zinc anode (Zn/ZnO), an alkaline …

Black mass (BM) from spent alkaline Zn-MnO 2 batteries was used for the first time as a Mn
source in the preparation of Mn/TiO 2 catalysts for low-temperature NH 3-selective catalytic …

Triboelectric nanogenerators (TENGs) have been extensively studied in recent years due to
their potential for energy harvesting and self-powered sensing. However, most of the …

Spent alkaline and zinc-carbon batteries contain valuable elements (notably, Zn and Mn),
which need to be recovered to keep a circular economy. In this study, the black mass …

Recycling/upcycling alkaline batteries are significant for the sustainable development. Here,
for the first time, we upcycle spent alkaline batteries into rechargeable Zn metal batteries …

Acidic zinc− carbon dry batteries have been widely used in life because of their low cost.
However, a great quantity of used batteries is discarded as refuse, which not only wastes …

There is a serious threat of pollution due to the high waste of energy and materials
worldwide that needs to be decreased. One way is to reduce waste or use them in …

A simple and chemical-free recycled carbon-ZnMn 2 O 4 powder (composite) from the spent
Zn-carbon batteries is proposed as an effective active material for the supercapacitor. This …
