The best of two worlds: Solar hydrogen production breakthrough
Using a simple solar cell and a photo anode made of a metal oxide, HZB and TU Delft scientists have successfully stored nearly five percent of solar energy chemically in the form of hydrogen. This is a major ...
Using bacteria batteries to make electricity
(Phys.org) —Their idea is state of the art: Ten Bielefeld students have set their sights on constructing a bio-battery. They want to make use of the bacteria Escherichia coli to convert glucose into energy. ...
Scientists power mobile phone using urine
British scientists on Tuesday reported they had harnessed the power of urine and were able to charge a mobile phone with enough electricity to send texts and surf the internet.
Phone and car batteries could use silicon made from rice
Eavesdropping on lithium ions
(Phys.org) —Lithium ion batteries are at the energetic heart of almost all things tech, from cell phones to tablets to electric vehicles. That's because they are a proven technology, light, long-lasting ...
Unzipped nanotubes unlock potential for batteries
(Phys.org) —Researchers at Rice University have come up with a new way to boost the efficiency of the ubiquitous lithium ion (LI) battery by employing ribbons of graphene that start as carbon nanotubes.
New framework from boron and silicon could smooth the way to higher capacities for lithium-ion batteries
Laptops could work longer and electric cars could drive farther if it were possible to further increase the capacity of their lithium-ion batteries. The electrode material has a decisive influence on a battery's ...
Graphene-boron mix shows promise for lithium-ion batteries
Frustration led to revelation when Rice University scientists determined how graphene might be made useful for high-capacity batteries.
Electrolysis method described for making 'green' iron
Anyone who has seen pictures of the giant, red-hot cauldrons in which steel is made—fed by vast amounts of carbon, and belching flame and smoke—would not be surprised to learn that steelmaking is one of the world's leading ...
New technique to improve quality control of lithium-ion batteries
(Phys.org) —Researchers have created a new tool to detect flaws in lithium-ion batteries as they are being manufactured, a step toward reducing defects and inconsistencies in the thickness of electrodes ...
Designing the clean-tech cars of the future
Ditching petrol for a clean-tech electric car sounds like an earth-saving move in theory. But if your charge is going to run out half way through your journey, it's not very practical to make the switch.
XGS presents new silicon-graphene anode materials for lithium-ion batteries
Bacterial boost for clean energy
(Phys.org) —Bacteria are often associated with their disease-causing capacity or alternatively, with their role as normal residents of the human body, where they perform duties essential to health.
