While electrochemical degradation in lithium-ion batteries is well studied, the role of stack pressure in long-term cycling remains unclear. Here the researchers use a high-precision pressure-controlled dilatometry tool to optimize stack pressure and understand how it prolongs battery lifetime.

Converting plastic waste into jet fuel could support aviation decarbonization, but current approaches are limited by high-pressure requirements and low efficiency. Here the authors present a tandem hydropyrolysis and vapour-phase hydrogenation strategy that uses a Ru/Co-Al oxide catalyst, achieving promising rates and yields at low pressures.
