Nature Energy, Published online: 14 May 2024; doi:10.1038/s41560-024-01540-8Realizing fast-charging and energy-dense lithium-ion batteries remains a challenge. Now, a porous current collector has been conceptualized that halves the effective lithium-ion diffusion distance and quadruples the diffusion-limited rate capability of batteries to achieve fast...

Nature Energy, Published online: 14 May 2024; doi:10.1038/s41560-024-01511-zThe European Commission has set a regulatory benchmark for classifying green hydrogen in the European Union. New research finds that by regulating the power purchase for electrolysers, emission savings from green hydrogen production is ensured, but cost is also affected.

Nature Energy, Published online: 14 May 2024; doi:10.1038/s41560-024-01531-9The costs of battery and fuel cell systems for zero-emission trucks are primed to decline much faster than expected, boosting prospects for their fast global diffusion and electrification of freight transport, with battery-electric trucks probably leading.

Nature Energy, Published online: 09 May 2024; doi:10.1038/s41560-024-01527-5It is challenging to design anti-freezing electrolytes for extremely low-temperature aqueous batteries. This study proposes a general guideline for designing anti-freezing electrolytes by choosing H2O–solute systems with low eutectic temperature and strong super-cooling ability,...

Nature Energy, Published online: 03 May 2024; doi:10.1038/s41560-024-01526-6Achieving good electrical contact without damaging underlying layers is critical to the performance of photovoltaic modules. Research now reports a silver electrode embedded into a polymer matrix and a silver/chromium protection layer, enabling over 14%-efficient flexible organic...

Nature Energy, Published online: 30 April 2024; doi:10.1038/s41560-024-01525-7Ensuring rooftop solar photovoltaics are deployed equitably requires understanding who installs, where, and when. Through assessment of satellite imagery data, research offers a glimpse into solar rooftop photovoltaics deployment inequity in non-residential buildings in the...
