Modern alchemists are making chemistry greener

Image result for cobalt

Researchers have found a revolutionary approach that uses  and methanol to produce an epilepsy drug that previously required rhodium and dichloromethane, a toxic solvent. Their new reaction works faster and more cheaply, and it likely has a much smaller environmental impact, said Chirik, the Edwards S. Sanford Professor of Chemistry.

#Graphene makes its mark on gas separation

Polymer-based membranes for gas separation have a trade-off between high gas permeability and high gas selectivity, the so-called Robeson upper bound. By combining individual graphene oxide sheets with polymer spacers, in a sandwich style structure, Graphene Flagship researchers have been able to overcome such limit, separating gas quickly and efficiently.

Focusing on producing a gas separation device useful for carbon capture and storage, the researchers devised a protocol to separate CO2from H2. Hydrogen production, both from natural gas or in gasification of liquid or solid fuels, is often accompanied by the formation of a significant amount of CO2, which needs to be removed before the gas is used. Efficient separation of the CO2has greater potential for capture of this greenhouse gas.

Vale inks first-ever cobalt streaming deal from Canada’s Voisey's Bay mine

#Brazil’s mining giant #Vale  has inked a pioneering agreement to sell future production of cobalt from its Canadian Voisey’s Bay mine, located in the Atlantic province of Newfoundland and Labrador, as speculation rises over a shortage of the metal needed to make batteries and which has been pushing companies to secure long-term supply.

#Tesla May Be Trampled by #CATL in #China

China LIthium Global Power

By the looks of it, every car of the future will be equipped with a powerful and cheap battery made in, and more importantly by, China.

This month, #Nissan Motor Co. and #Daimler AG put in orders for electric-car batteries with an emerging #Chinese champion, privately held Contemporary Amperex Technology Co., or #CATL. #Volkswagen AG is already a customer, as is the joint venture of #BMW AG and Brilliance #China Automotive Holdings Ltd. That’s quite an endorsement of the battery maker’s know-how.
Almost 90 percent of #CATL’s revenue comes from making #Lithium-ion batteries. It’s moved beyond lithium iron phosphate technology to produce more advanced, higher-energy-density forms that use #Nickel, #Cobalt and #Manganese.

#Tesla delivers bad news for #Cobalt price, boost for rare earths

Slide 1Tesla is a proponent of #Nickel-#Cobalt-#Aluminium (NCA) technology which requires less than a third the amount of cobalt.

Nickel-Manganese-Cobalt (NMC) batteries favoured by most vehicle makers contain around 20% cobalt.

Musk said on Wednesday the cobalt content of its NCA cathode chemistry “is already lower than next-generation cathodes that will be made by other cell producers with a nickel-manganese-cobalt ratio of 8:1:1″.

#Nickel intermediates can fill class one supply gap – #Vale



#Nickel intermediates could provide the most cost-effective means of bringing on-stream additional class one nickel units to serve the growing battery market – #Vale.

Nickel demand from the battery sector could increase to 1.8 million tonnes by 2030 from 700,000 tonnes by 2025, according to Vale’s upside forecast. Its more conservative forecast suggests demand of 350,000 tonnes in 2025 and of 1 million tonnes by 2030.

“There is no better chemistry available than lithium-ion and it favors nickel in a big way; the more nickel the better, the greater the energy density,”.

“And the more nickel you add, the cheaper it becomes – your battery cost comes down significantly,”.

Future of #Vale’s #Nickel operation in #NewCaledonia?

Goro nickel mine, New Caledonia

RIO DE JANEIRO, April 26, 2018 (Reuters) – #Brazil’s #Vale hopes to find a partner for its struggling #NewCaledonia #Nickel mine by the end of the year but it is not clear if the world’s largest nickel producer will continue nickel operations there, executives said.
