Science | Iranian researcher develops plan to extend battery life / Low-cost sheet enables water purification

Pars Today — An Iranian researcher has developed a project aimed at extending the lifespan of lead-acid batteries.

The project titled “Improving the Storage Capacity and Lifespan of Lead-Acid Batteries Using Graphene Aerogel Composite as an Additive” was carried out with support from the Iran National Science Foundation.

According to Pars Today, citing Mehr News Agency, Ghazitabar of Amirkabir University of Technology explained that, given Iran’s existing infrastructure for lead-acid battery production, the application of advanced technical knowledge to improve battery properties could lead to more efficient energy storage systems suitable for diverse applications — without requiring major changes to existing manufacturing facilities.

Ghazitabar noted that the newly developed battery offers greater lifespan and capacity compared to conventional models, emphasizing that extending battery life and enhancing capacity will lead to higher consumer satisfaction and open the way for new applications of these batteries.

Water purification made possible with low-cost sheet

Researchers at Sun Yat-sen University in China have developed a new water purification sheet. This self-floating photocatalytic sheet uses minimal sunlight to clean heavily contaminated water and eliminate bacteria.

The invention offers a simple, inexpensive, and effective solution to the clean drinking water crisis. According to the study, the disinfecting sheet is particularly suitable for regions facing water scarcity or limited resources. The researchers note that its low energy requirement, high efficiency, and operational simplicity make it practical for real-world applications in resource-constrained areas.
