Johnny heath corpus christi Affordable Hydrogen Fuel Cells News You’ll never 'be-leaf' what makes up this battery!

Scientists have a new recipe for batteries: Bake a leaf, and add sodium. They used a carbonized oak leaf, pumped full of sodium, as a demonstration battery’s negative terminal, or anode, according to a paper published yesterday in the journal ACS Applied Materials Interfaces.

Johnny heath corpus christi Affordable Hydrogen Fuel Cells News Putting silicon 'sawdust' in a graphene cage boosts battery performance

Scientists have been trying for years to make a practical lithium-ion battery anode out of silicon, which could store 10 times more energy per charge than today's commercial anodes and make high-performance batteries a lot smaller and lighter. But two major problems have stood in the way: Silicon particles swell, crack and shatter during battery charging, and they react with the battery electrolyte to form a coating that saps their performance.

Johnny heath corpus christi Affordable Hydrogen Fuel Cells News Harnessing the oxidizing power of air

Researchers report the catalysis of a highly specific chemical reaction where oxygen from the air is one ingredient and the other, an organic molecule, is selectively 'oxidized'. A simple manganese compound catalyses this reaction. This type of methodology is an important step for the discovery of new catalysts, for example, for the conversion of methane into methanol or greener chemical processes for pharmaceutical production.

Johnny heath corpus christi Affordable Hydrogen Fuel Cells News Alternative to platinum: Iron-nitrogen compounds as catalysts in graphene

A cost-effective catalyst material has been produced for fuel cells using a new preparation process which researchers analyzed in detail. It consists of iron-nitrogen complexes embedded in tiny islands of graphene only a few nanometres in diameter. It is only the FeN4 centres that provide the excellent catalytic efficiency -- approaching that of platinum. The results are interesting for solar fuels research, they say.
