Lawrence Berkeley National Laboratory has developed a material for cathodes in li-ion batteries called Layered-Rocksalt Intergrown Battery Electrode Material which ensures high capacity, fast charging time and energy transfer, and superior cycling and thermal stability. The material can be synthesised under ambient atmosphere, easing processing and reducing production costs. Its thermal stability and minimal gas release reduce fire ...

The UK Space Agency (UKSA) has awarded £650,000 to Northumbria University to continue its work to develop what it describes as the first commercially available laser-based inter-satellite communications system. Their CubeSats use lasers, instead of radio frequency, for data transmissions with more capacity and security. And the aim is to develop an “off the shelf” ...
