Researchers have shown that rigid lithium-ion batteries can be made more suitable for smart watches and other flexible electronics.
Backing from disparate investors such as General Motors and a vacuum maker has given the battery startup Sakti3 an unusual amount of momentum.
Rapid industrialization and rising standards of living have made China the world’s top emitter of carbon dioxide. Preventing a runaway increase will require the country to keep per capita emissions at a relatively low level.
A startup from one of the A123 founders aims to overhaul the making of lithium-ion batteries--but it’s not the first to try.
As the Pope calls for action on climate change, a growing body of evidence shows that low-latitude countries will feel the heaviest effects of global warming.
Devices produce electricity from spores resting on water’s surface, but practical applications remain distant.
Automakers have begun harvesting batteries for use in stationary energy storage applications.
Is there a realistic roadmap to 100% renewables?
Manufactured materials could lead to breakthroughs in batteries, supercapacitors, and eventually carbon-capture systems.
Predicted lithium shortages are leading to novel technologies for recovering the element, now found mostly in salt lakes in South America.
