LME Zinc Hits 14-Year High As European Smelters Halve Output Amid Energy Crunch, page-78

Excerpt

“Rechargeable zinc-air batteries (ZABs) are becoming more appealing because of their low cost, environmental friendliness, high theoretical energy density, and inherent safety,” said Azhar.

Lithium batteries rely on high-cost, finite resources, and also have safety issues.

”With the emergence of next-generation long-range vehicles and electric aircraft in the market, there is an increasing need for safer, more cost-effective, and high-performance battery systems that can surpass the capabilities of lithium-ion batteries,” said Azhar. “By using natural resources, such as zinc from Australia and air, this further enhances the cost-effectiveness and viability of these innovative zinc-air batteries for the future.”

Why Li-ion batteries were allowed into the vehicle market without the same rigorous testing is beyond me.
