The battery technology industry has seen a rapid growth in recent years as countries increasingly switch to clean-powered electric mobility. Currently across the world, four types of batteries are in use: lead acid, lithium-ion (including variants), nickel-metal hydride and vanadium ion batteries. While lead acid and lithium-ion batteries are the only two currently available in the Indian market, several other technologies like vanadium redox, metal-air, metal-ion and liquid metal batteries are also being explored for application across sectors.
Parveen Kumar, senior programme manager, Electric Mobility at the World Resources Institute, a global research non-profit, tells Down To Earth (DTE) that four factors determine whether a new battery technology disrupts the market-energy density (amount of charge in a unit area), cost, safety (health impacts, flammability and explosiveness) and sustainability (including global availability).

BRACE FOR STILL WINDS
Wind circulations are slowing down across the globe. It may not be immediately apparent in terms of wind speed, which is a local phenomenon. But scientists say global stilling of wind affects almost every aspect of our lives—from unpredictable rainfall to excess heatwaves to frequent or missing storms. It even affects wind energy production and the aviation sector. Evidence shows a clear connection between global warming and wind stilling. Could this be the missing piece in climate models?
