We use batteries in many different things including computers, laptops, cars, radios, mobile phones, clocks, watches, and much more.

Batteries are made from a variety of chemicals to power their reactions and some of these chemicals, such as nickel and cadmium, are extremely toxic and can cause damage to humans and the environment in form of soil and water pollution and endangering wildlife.

Now, a new research project developed by scientists of the University of Maryland hopes to change the situation at least on the small-scale.

A team led by professor Hongli Zhu has succeeded in creating a nanoscale rechargeable battery from the most environmentally friendly material there is — wood. This alternative to existing batteries would be benign when disposed of and very cheap to manufacture.
