Using hydrogen to enhance lithium ion batteries

Lithium ion batteries operate longer and faster when treated with hydrogen.


Lithium ion batteries (LIBs) are a class of rechargeable battery types in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. The growing demand for energy storage emphasizes the urgent need for higher-performance batteries. ...


It's solid: Storing hydrogen in a new form


As part of a tri-lab consortium, Lawrence Livermore National Laboratory researchers will develop tools and understanding necessary for designing new solid-state materials for storing hydrogen gas. Storage of hydrogen onboard vehicles is one of the critical enabling technologies for ...

Discovery of a highly efficient catalyst eases way to hydrogen economy


Hydrogen is usually produced by separating water with electrical power. And although the water supply is essentially limitless, a major roadblock to a future "hydrogen economy" is the need for platinum or other expensive noble metals in the water-splitting devices.Noble metals resist oxidation ...

Chemists find new way to do light-driven reactions in solar energy quest

The more efficient method opens another possible pathway to harness sunlight for energy


Chemists have found a new, more efficient method to perform light-driven reactions, opening up another possible pathway to harness sunlight for energy. The journal Science is publishing the new method, which is based on plasmon - a special motion of electrons involved in the optical properties of ...


NIST calculates high cost of hydrogen pipelines, shows how to reduce it


The National Institute of Standards and Technology (NIST) has put firm numbers on the high costs of installing pipelines to transport hydrogen fuel - and also found a way to reduce those costs.Pipelines to carry hydrogen cost more than other gas pipelines because of the measures required to ...


PNNL Hydrogen Catalysis Team win ACS award


ACS Catalysis and the American Chemical Society (ACS) Division of Catalysis Science & Technology are announced Morris Bullock, Ph.D., Daniel DuBois, Ph.D., and the Hydrogen Catalysis Team at the Pacific Northwest National Laboratory (PNNL) have won the 2015 ACS Catalysis Lectureship for the ...

The simplest element: Turning hydrogen into 'graphene'


New work from Carnegie's Ivan Naumov and Russell Hemley delves into the chemistry underlying some surprising recent observations about hydrogen, and reveals remarkable parallels between hydrogen and graphene under extreme pressures. Their work is the cover story in the December issue of Accounts ...


A new solution for storing hydrogen fuel for alternative energy


Turning the "hydrogen economy" concept into a reality, even on a small scale, has been a bumpy road, but scientists are developing a novel way to store hydrogen to smooth out the long-awaited transition away from fossil fuels. Their report on a new solid, stable material that can pack in a large ...


Chemists challenge conventional understanding of how photocatalysis works

New model proposed by UC Riverside researchers could help identify better promoters for photocatalysis


Photocatalysis is a promising route to convert solar energy into chemical fuels. Particularly appealing is the possibility to use photocatalysis to split water molecules into molecular hydrogen. Although photocatalysis has been around for many years, the search for viable photocatalysts to ...

Halving hydrogen

First view of nature-inspired catalyst after ripping hydrogen apart provides insights for better, cheaper fuel cells


Like a hungry diner ripping open a dinner roll, a fuel cell catalyst that converts hydrogen into electricity must tear open a hydrogen molecule. Now researchers have captured a view of such a catalyst holding onto the two halves of its hydrogen feast. The view confirms previous hypotheses and ...
