🔆 DST Scientists Develop Electrolyte Additive for Safer & Affordable Aqueous Zinc-Ion Batteries

📍 Why in Focus?
Scientists at the Institute of Nano Science and Technology (INST), Mohali, an autonomous institute under the Department of Science & Technology (DST), have developed a novel electrolyte additive that significantly improves the performance and lifespan of Aqueous Zinc-Ion Batteries (AZIBs).

📍 Key Highlights:
✅ Researchers developed a new electrolyte additive BDIM (1,3-bis(1,3-dicarboxypropyl)-1H-imidazole-3-ium chloride) to enhance the stability of Aqueous Zinc-Ion Batteries (AZIBs).
✅ The additive suppresses hydrogen evolution, corrosion and zinc dendrite formation, improving battery safety, cycle life and charging performance.
✅ AZIBs are emerging as low-cost, safer and sustainable alternatives to Lithium-ion batteries, especially for grid-scale renewable energy storage.
✅ Scientists used advanced techniques such as Ultramicroelectrode (UME) and Fast-Scan Cyclic Voltammetry (FSCV) to study zinc deposition and interfacial charge-transfer mechanisms.
✅ The innovation can support renewable energy integration, backup power systems and sustainable energy infrastructure by reducing battery degradation and maintenance costs.

📍 Challenges / Issues / Implications:
✅ Commercialisation and large-scale manufacturing of advanced battery technologies.
✅ Reducing dependence on imported energy storage technologies and critical minerals.
✅ Scaling affordable, safe and efficient battery storage to support India’s clean energy transition.

✅ Mains Question (GS III | 150 Words):
“Discuss the significance of next-generation battery technologies such as Aqueous Zinc-Ion Batteries (AZIBs) in achieving India’s renewable energy and energy storage goals. Highlight the challenges in their commercial adoption.”
