Are zinc-air batteries safe for vehicles?

Hindustan Zinc Ltd and IIT Madras, working under a Memorandum of Understanding (MoU), have developed the prototype for electrically-rechargeable zinc-air batteries. These batteries are claimed to be safe for vehicles since they use water-based electrolytes and no flammable materials. Their life cycle is longer than that of lithium-ion.

Are zinc-air batteries good for cyclic stability?

Recent research has proven the use of water-based electrolytes and batteries with wider operating temperatures. In fact, zinc-air batteries have already been found suitable for appliances that require a very low rate of discharge, such as hearing aids or sonobuoys. However, the low rate of discharge leads to poor cyclic stability.

Are zinc-air batteries a viable alternative to Li-ion batteries?

Of all the chemistries, zinc-air batteries have been a feasible alternative to Li-ion, addressing most of the shortcomings that Li-ion batteries have struggled with. Hindustan Zinc Ltd and IIT Madras, working under a Memorandum of Understanding (MoU), have developed the prototype for electrically-rechargeable zinc-air batteries.

How can India achieve a large-scale commercialisation of batteries?

However, to achieve large-scale commercialisation, the market must strictly operate on a circular economy, especially since India does not have the metals required for batteries. “There should be a proper ecosystem to convert recycled materials into battery raw materials,” points out Trikha.

Is zinc battery recyclable?

Of all its features, the easy replaceability and recyclability of zinc are driving market enthusiasm. “Approximately 80% of zinc used globally is sourced from recycled materials. The recycling process for zinc batteries is less energy-intensive and straightforward.

Is zinc a growth opportunity for small and Medium Manufacturers?

Regarding growth opportunities for small and medium manufacturers, Trikha adds, “There are niche markets requiring specialized designs, like defense, that are ignored by large manufacturers. Innovations are also easier at a smaller scale.” Of all its features, the easy replaceability and recyclability of zinc are driving market enthusiasm.
