UD invention aims to improve battery performance

Imagine a world where cell phones and laptops can be charged in a matter of minutes instead of hours, rolled up and stored in your pocket, or dropped without sustaining any damage. It is possible, according to University ...

Polymer professor develops safer component for lithium batteries

The power source for implanted medical devices, electric cars, unmanned aerial vehicles and other such objects is vital to their performance. So, what would happen if that powerhouse of energy—a lithium battery—failed? ...

A new polymer raises the bar for lithium-sulfur batteries

Lithium-sulfur batteries are promising candidates for replacing common lithium-ion batteries in electric vehicles since they are cheaper, weigh less, and can store nearly double the energy for the same mass. However, lithium-sulfur ...

Freezing lithium batteries may make them safer and bendable

Yuan Yang, assistant professor of materials science and engineering at Columbia Engineering, has developed a new method that could lead to lithium batteries that are safer, have longer battery life, and are bendable, providing ...
