Advancing Green Energy Storage: Indian Scientists Develop Novel Additive for Aqueous Zinc Batteries
GS3
Scientists at the Institute of Nano Science and Technology (INST) have developed a novel electrolyte additive, BDIM, to resolve critical issues in Aqueous Zinc Ion Batteries (AZIBs). This breakthrough addresses zinc dendrite growth and corrosion, paving the way for affordable, durable, and scalable renewable energy storage solutions.
In a significant boost to India's clean energy transition and indigenous technological capabilities, scientists from the Institute of Nano Science and Technology (INST), Mohali—an autonomous institute under the Department of Science and Technology (DST)—have developed a novel electrolyte additive called BDIM. This breakthrough addresses the long-standing challenges of Aqueous Zinc Ion Batteries (AZIBs), positioning them as a viable, low-cost, and safer alternative to conventional lithium-ion batteries for large-scale grid storage.
While lithium-ion batteries dominate the current energy storage market, they suffer from high costs, safety hazards (such as thermal runaway), and supply chain vulnerabilities due to limited lithium reserves. AZIBs, which utilize water-based electrolytes and abundant zinc, offer a safer and cheaper alternative. However, their commercialization has been hindered by issues like zinc dendrite growth (needle-like structures that cause short circuits), hydrogen evolution, and corrosion, which drastically reduce battery life.
