Project HiQ-CARB aims to provide new carbons with a superior performance and a low carbon footprint for future green batteries in Europe
Lithium-ion batteries require in addition to lithium metal a number of sophisticated functional materials for their performance. Some of them sound rather unspectacular: conductive additives. In fact, conductive additives like carbon black or carbon nanotubes are a decisive component for the ...
Scientists achieve defect control with a new reaction pathway
The properties of carbon-based nanomaterials can be altered and engineered through the deliberate introduction of certain structural “imperfections” or defects. The challenge, however, is to control the number and type of these defects. In the case of carbon nanotubes – microscopically small ...
Novel technique yields a carbon nanotube forest of record length, potentially revolutionizing the future of many industries
Today, a multitude of industries, including optics, electronics, water purification, and drug delivery, innovate at an unprecedented scale with nanometer-wide rolls of honeycomb-shaped graphite sheets called carbon nanotubes (CNTs). Features such as light weight, convenient structure, immense ...
It’s all about good cooperation
By splitting water electrochemically, green hydrogen can be produced, which can be used as fuel, energy storage and for chemical reactions. This way, we can decrease our dependence on fossil resources and reduce greenhouse gas emissions. However, the electrolysis of water consumes a lot of ...
Novel nanostructure design lends extraordinary strength to a promising storage ingredient
The same material you'll find at the tip of a pencil--graphite--has long been a key component in today's lithium-ion batteries. As our reliance on these batteries increases, however, graphite-based electrodes are due for an upgrade. For that, scientists are looking to the element at the heart of ...
A Korean research team has succeeded in developing next-generation high-capacity cathode material for lithium-ion batteries. The Korea Institute of Science and Technology (KIST, Acting President Seok-jin Yoon) announced that the joint research team of Dr. Kyung Yoon Chung (head of the Center for ...
One nanotube could be great for electronics applications, but there's new evidence that two could be tops. Rice University engineers already knew that size matters when using single-walled carbon nanotubes for their electrical properties. But until now, nobody had studied how electrons act when ...
In a recently published paper in Science Advances, Feng Ding of the Center for Multidimensional Carbon Materials, within the Institute of Basic Science (IBS, South Korea) and colleagues, have achieved the creation of a specific type of carbon nanotubes (CNTs) with a selectivity of 90%, and ...
Scientists from Tokyo Metropolitan University have used aligned "metallic" carbon nanotubes to create a device which converts heat to electrical energy (a thermoelectric device) with a higher power output than pure semiconducting carbon nanotubes (CNTs) in random networks. The new device bypasses ...
A research collaboration between Rice University and the Energy Safety Research Institute (ESRI) at Swansea University has found that old newspapers can be used as a low cost, eco-friendly material on which to grow single walled carbon nanotubes on a large scale. Carbon nanotubes are tiny ...
