HydroGraph Clean Power has announced that according to a study published in the Journal of Electrochemical Energy Conversion and Storage, HydroGraph’s graphene surpassed the performance of the leading cathode carbon materials in a lithium-oxygen (Li-O2) battery test.

Lithium-oxygen batteries have emerged a promising energy storage solution, but global adoption has been hampered in achieving efficient electrocatalysis, which impacts a battery’s performance. Using HydroGraph’s patented high-purity fractal graphene, battery scientists have reportedly overcome performance challenges, allowing for a better performing battery at a lower cost compared to the incumbent.

Stellantis and Lyten have announced that Stellantis Ventures, the corporate venture fund of Stellantis, invested in Lyten to accelerate the commercialization of Lyten 3D Graphene™ applications for the mobility industry, including the LytCell™ Lithium-Sulfur EV battery, lightweighting composites, and novel on-board sensing. 

Lyten will aim to leverage the tunability of the material to enable enhanced vehicle performance and customer experience while decarbonizing the transportation sector. Lyten’s tunable materials platform has demonstrated significant reductions in greenhouse gas emissions and will advance the transition to sustainable mobility.

Earlier this year, Tohoku University researchers created a technique that could micro/nanofabricate silicon nitride thin devices with thicknesses ranging from 5 to 50 nanometers. The method employed a femtosecond laser, which emitted extremely short, rapid pulses of light. It turned out to be capable of quickly and conveniently processing thin materials without a vacuum environment.

By applying this method to an ultra-thin atomic layer of graphene, the same group has now succeeded in performing a multi-point hole drilling without damaging the graphene film. 

Haydale has announced that it will be a key contributor to Viritech's development of fuel cell hydrogen electric vehicles (FCHEVs).

Viritech, a developer of high-performance hydrogen powertrain solutions for the automotive industry, has secured a major role in Ford Motor Company's three-year hydrogen fuel cell E-Transit trial and Haydale will lead the development of new functionalized materials and resins for Type V pressure vessels to support Viritech's proprietary integrated mounting system Graph-Pro™.
