Technical review outlines challenges for both batteries and fuel cells as basis for electric vehicles

Green Car Congress

Based on other studies, they note that without an increasing percentage of renewables in the European electricity generation mix, the only vehicle concept which could meet the 95 gCO 2 /km target is the pure battery electric vehicles. wind and solar). Source: Gröger et al. Click to enlarge.

Stanford team reports 3D electrode structure addressing major limiting characteristics of sulfur cathodes for Li-S batteries

Green Car Congress

The researchers suggested that their results showed that the inverse opal structure of hydrogen-reduced TiO 2 represents an effective strategy in improving the performance of lithium sulfur batteries. And this concept opens up a new avenue for constructing sulfur cathodes with metal oxides. —Liang et al.
