Indian scientists have created an upgraded cathode material that significantly increases the energy-storage capacity and lifespan of zinc-ion batteries, according to a statement issued by the Ministry of Science and Technology.
A research team has developed a thermo-electrochemical activation process that alters the structure of vanadium oxide. The treatment introduces controlled defects, producing a zinc–vanadium oxide (Zn-V2O5) material with improved stability and expanded pathways for zinc-ion movement.
The modified structure enables zinc-ion batteries to store substantially more energy and withstand thousands of charge cycles with minimal performance loss. Officials noted that the innovation offers a simple and efficient way to enhance the energy density and durability of widely used cathode materials. This is reported by
IANS, a partner of TV BRICS.
Zinc-ion batteries have recently gained attention as a safer and more environmentally friendly alternative to lithium-based systems. While lithium batteries dominate due to their high energy density, they pose environmental and safety challenges. Zinc-ion technology, by contrast, benefits from high storage capacity, improved safety and greater sustainability.
The ministry said the newly developed Zn-V2O5 material could accelerate the advancement of next-generation zinc-ion batteries, supporting broader efforts to expand clean and reliable energy-storage solutions.
