The recycling of lithium-ion batteries is vitally important to the future of electric power, explains Gregg Smith at Orbia Advance, writing for WEF. Making a battery has a significant carbon footprint of its own. Yet recycling can be one tenth the cost of manufacturing a battery from scratch. And energy security is enhanced by lessening dependence on mining countries and other suppliers. It’s why Europe will require new batteries to contain at … [Read more...]
Research into how electrons and protons couple at an electrode can create more efficient fuel cells, electrolysers
Every efficiency gain discovered in the lab feeds through to the final cost of electricity. Anne Trafton at MIT describes new research looking at how electrons and protons couple at an electrode surface, which drives electric current. It’s a critical step in many energy technologies, including fuel cells, hydrogen electrolysers, batteries, and CO2 conversion into chemical fuels. The first step was to develop a way to design electrode surfaces … [Read more...]
Fuel Cells and Electrolysis: nanoparticle catalyst electrodes can advance clean power and Hydrogen production
Fuel and electrolysis cells both involve electrochemical reactions (one is the reverse of the other), and their efficiency depends on the catalysts used on the electrodes. Conventional metal catalysts coarsen at high temperatures, reducing activity and durability. Elizabeth Thomson at MIT describes new research there that uses ion irradiation to precipitating metal nanoparticles onto the surface of the electrode. The process allows close control … [Read more...]
Making Hydrogen direct from seawater using double-membrane electrolysis
Can hydrogen be produced from seawater? The standard method requires water to be purified, which is expensive to do and adds complexity to the device. David Krause at the SLAC National Accelerator Laboratory, Stanford University describes new research there that uses electrolysis and a double membrane directly on the seawater to separate out the chloride and isolate the hydrogen and hydroxides. The system operates without generating toxic … [Read more...]
Using atomic-scale imaging and AI to reduce Battery degradation
Finding ways to extend a battery’s life starts with understanding why they degrade. Andrew Myers writing for Stanford University describes research there that is using new methods of high-resolution X-ray, electron and neutron microscopy to allow direct visualisation of battery materials at the nanoscale. Degradation is mostly caused by the expansion and contraction of the materials. The high resolution images are processed using AI to uncover … [Read more...]
