Lithium-ion batteries (LIBs), integral to modern technology, consist of various components, including a cathode that often contains cobalt. While cobalt-based cathodes offer advantages like longer life expectancy, there are efforts to reduce their cobalt content to cut costs while maintaining performanc...
Car and tech companies are scrambling for supplies of cobalt, a mineral they need to power electric vehicles and smartphones. But they have a problem: Much of the cobalt used in lithium-ion batteries comes from a country where children work in mines. A CNN investigationhas found that child...
The sustainability of cobalt is an important emerging issue because this critical base metal is an essential component of lithium-ion batteries for electric vehicles. More than half of the world’s cobalt mine production comes from the Katanga Copperbelt in DR Congo, with a substantial proportion ...
Lithium-ion batteries (LIBs) to power electric vehicles play an increasingly important role in the transition to a carbon neutral transportation system. However, at present the chemistry of LIBs requires, among other elements, cobalt (Co), which will probably become scarce over time in addition to...
MIT researchers have now designed a battery material that could offer a more sustainable way to power electric cars. The new lithium-ion battery includes a cathode based on organic materials, instead of cobalt or nickel (another metal often used in lithium-ion batteries). ...
What does the rise of electric vehicles mean for two critical raw materials that go into their batteries—and for the players in this ecosystem?
