Rechargeable batteries

Scientists are developing a new lightweight car battery made partly of air.

Researchers at the University of California, Los Angeles, are developing nano-batteries, the largest of which will be no bigger than a grain of salt.

MIT professor Don Sadoway thinks massive batteries made from liquid metals might let us use more renewable energy. If his revolutionary batteries could store the energy produced by wind and solar power, we could then use that electricity at times when the

The U.S. recycles almost all car batteries, but that’s not true in many developing countries. Sifting through waste to retrieve lead is a major source of income, and lead exposure, for many people in poorer countries. Living on Earth reports.
