New method increases energy density in lithium batteries

Yuan Yang, assistant professor of materials science and engineering at Columbia Engineering, has developed a new method to increase the energy density of lithium (Li-ion) batteries. He has built a trilayer structure that ...

High-efficiency zinc-air battery developed

Stanford University scientists have developed an advanced zinc-air battery with higher catalytic activity and durability than similar batteries made with costly platinum and iridium catalysts. The results, published in the ...

A novel catalyst for high-energy aluminum-air flow batteries

A recent study affiliated with UNIST has introduced a novel electric vehicle (EV) battery technology that is more energy efficient than gasoline-powered engines. The new technology involves replacing battery packs instead ...

Renaissance of the iron-air battery

Iron-air batteries promise a higher energy density than present-day lithium-ion batteries. Their main constituent, iron, is an abundant and cheap material. Scientists from Forschungszentrum Jülich are pursuing research into ...

Air pollution: The silent killer called PM2.5

Millions of people die prematurely every year from diseases and cancer caused by air pollution. The first line of defense against this carnage is ambient air quality standards. Yet, according to researchers from McGill University, ...

What's the best design for a flying Mars robot?

Building a flying vehicle for Mars would have significant advantages for exploration of the surface. However, to date, all of our surface exploring vehicles and robotic units on Mars have been terrestrial rovers. The problem ...

Titanic's sinking: Was it more than human folly

(AP) -- After an entire century that included two high-profile government investigations and countless books and movies, we're still debating what really caused the Titanic to hit an iceberg and sink on that crystal-clear ...
