BMW iX5 Hydrogen in final winter testing close to the Arctic Circle

Green Car Congress

Under these cold conditions, the hydrogen fuel cell drive system displays the same everyday usability as a conventional internal combustion engine. The hydrogen it uses as an energy source is stored in two 700-bar tanks made from carbon-fibre-reinforced plastic (CFRP). Full system power quickly comes on tap.

JAIST black-glasses-grafted silicon microparticles as anode material for improving battery performance

Green Car Congress

SiMPs are the most appropriate, low-cost, and easily available alternatives, especially when combined with materials that have exceptional structural properties, such as silicon oxycarbide black glasses. This screening showed that the material has great lithium diffusion ability, reduced internal resistance, and overall volumetric expansion.
