… A research team led by Kavita Pandey of the Centre for Nano and Soft Matter Sciences (CeNS), a Department of Science and Technology (DST) institute in Bengaluru, working in collaboration with researchers from Shiv Nadar Institution of Eminence in Greater Noida, has developed a new composite material that makes aluminium batteries more stable and longer-lasting.
“Aluminium batteries have attracted attention because aluminium is widely available, inexpensive, and can store more charge per atom than lithium. But there has been a major hurdle: the materials inside these batteries tend to break down quickly. Over repeated charging, they crack or dissolve into the liquid inside the battery, causing it to lose power,” DST pointed out…
The result is a composite that acts like a support structure, holding the battery material together while also helping electricity and ions move more smoothly.This seemingly simple change made a measurable difference. Tests showed that the new material reduced the amount of vanadium dissolving into the battery liquid by more than four times compared to the original material.
As a result, the battery retained more than 73% of its capacity after 100 charge cycles, and around 59% even after 500 cycles. In comparison, conventional versions degrade much faster. In practical terms, that means a battery that lasts longer and performs more reliably…
