Centre for Nano and Soft Matter Sciences (CeNS), Bengaluru & Aligarh Muslim University (AMU) have developed a lanthanum-doped silver niobate-based energy storage material, which has enhanced the performance of supercapacitors.
Lanthanum-Doped Silver Niobate Energy Storage Material:
- About: It is an advanced nanostructured compound made by doping silver niobate (AgNbO₃), a lead-free and eco-friendly perovskite material, with lanthanum, a rare-earth element.
- Significance:
- This doping has reduced nanoparticle size, increasing the surface area for energy storage, and improved electrical conductivity for faster charge-discharge cycles.
- It also ensured excellent energy retention (118%) with no energy loss during use (100% coulombic efficiency).
- It is also environmentally friendly, being lead-free and suitable for green energy applications.
- Applications: Used in portable electronics, electric vehicles (EVs), and renewable energy systems, demonstrated potential by successfully powering an LCD display through a prototype supercapacitor.
Supercapacitors:
- Supercapacitors, also known as ultracapacitors, are energy storage devices that bridge the gap between conventional capacitors and batteries.
- They offer high power density, rapid charge-discharge, and a long lifecycle (millions of cycles).
- Unlike batteries, they store energy through electrostatic charge separation rather than chemical reactions, making them safer and more durable.
- They have lower energy density than batteries, but this can be improved through material doping, such as with lanthanum-doped silver niobate.
