Bias-free solar hydrogen production at 19.8 mA cm⁻² using perovskite photocathode and lignocellulosic biomass

While light-driven water splitting offers a means to produce renewable H₂ fuel, water oxidation limits performances and yields low-value products. Here, authors demonstrate a photoelectrochemical cell that converts lignocellulosic biomass into valuable products alongside H₂.

Ultra-high-voltage Ni-rich layered cathodes in practical Li metal batteries enabled by a sulfonamide-based electrolyte

Charging at high voltages in principle makes batteries energy dense, but this is often achieved at the cost of the cycling stability. Here the authors design a sulfonamide-based electrolyte to enable a Li metal battery with a state-of-the-art cathode at an ultra-high voltage of 4.7 V while maintaining cyclability.

Visualizing interfacial collective reaction behaviour of Li–S batteries

In situ liquid-cell electrochemical transmission electron microscopy allows the direct visualization of the transformation of lithium polysulfides over electrode surfaces at the atomic scale, leading to a new energy-storage mechanism in lithium–sulfur batteries.
