Scientists at Tokyo Institute of Technology (Tokyo Tech), Tohoku University, National Institute of Advanced Industrial Science and Technology, and Nippon Institute of Technology, demonstrated by experiment that a clean electrolyte/electrode interface is key to realizing high-capacity solid-state lithium batteries. Their findings could pave the way for improved battery designs with increased capacity, stability, and safety for both mobile devices and electric vehicles.
Liquid lithium-ion batteries are everywhere, being found in the majority of everyday mobile devices. While they possess a fair share of advantages, liquid-based batteries carry notable risks as well. This has become clear to the public in recent years after reports of smartphones bursting into flames due to design errors that caused the battery s liquid electrolyte to leak and catch fire.

Chemical engineers at UNSW Sydney have found a way to make green ammonia from air, water and renewable electricity that does not require the high temperatures, high pressure and huge infrastructure currently needed to produce this essential compound.
And the new production method - demonstrated in a laboratory-based proof of concept - also has the potential to play a role in the global transition towards a hydrogen economy, where ammonia is increasingly seen as a solution to the problem of storing and transporting hydrogen energy.
In a paper published today in
Energy and Environmental Science, the authors from UNSW and University of Sydney say that ammonia synthesis was one of the critical achievements of the 20th century. When used in fertilisers that quadrupled the output of food crops, it enabled agriculture to sustain an ever-expanding global population.

Long before an advanced nuclear reactor begins to generate power or another complicated project comes to life, researchers and engineers model and simulate it to ensure success. Now a collaboration between Idaho National Laboratory and Orem, Utah-based Coreform makes this modeling and simulation faster, less costly and more efficient.
The partnership improves upon an open-source INL platform to make simulations more true to life, benefiting the many projects that leverage it.

A research team from the Institut national de la recherche scientifique (INRS) has joined forces with French researchers from the Institute of Chemistry and Processes for Energy, Environment and Health (ICPEES), a CNRS-University of Strasbourg joint research lab, to pave the way towards the production of green hydrogen. This international team has developed new sunlight-photosensitive-nanostructured electrodes. The results of their research were published in the November 2020 issue of the journal of
