How things break (and why scientists want to know)

Humans spend a lot of time creating things—this drives a huge amount of our lives, economically and personally—and we are always in a fight to keep them from breaking down. Houses, roads, cars. Power lines and bridges. ...

Built in sensors make lithium-ion batteries safer

Researchers in Penn State's Battery and Energy Storage Technology (BEST) Center are working to make the lithium-ion (Li-ion) batteries we use every day safer by inserting sensors to warn users of potential problems inside ...

Solar energy from discarded car batteries

MIT researchers have developed a simple procedure for making a promising type of solar cell using lead recovered from discarded lead-acid car batteries—a practice that could benefit both the environment and human health. ...

Electric cars—batteries with brains

The battery is the heart of the electric car. Fraunhofer researchers have developed an energy storage device which is significantly more cost-effective over the entire life cycle in comparison with previous models. If one ...

Solar battery receives 20% of its energy from the sun

(Phys.org)—Last October, researchers at Ohio State demonstrated the world's first solar battery—a solar cell and a lithium-oxygen (Li-O2) battery combined into a single device. The main attraction of the solar battery ...
