Stack pressure strongly influences degradation pathways in lithium-ion batteries, yet its optimal value remains poorly understood. Now, a high-precision stack pressure control and dilatometry system reveals an optimal pressure window that suppresses key degradation pathways and doubles battery lifetime.

Decarbonized grids may face rising resource adequacy risks as weather-driven renewable variability and climate change jointly affect supply and demand. A high-resolution model shows that these risks stem from multi-day power shortfalls and system design, but can be reduced through region-specific, climate-informed siting and transmission planning.Nature Energy, Published online: 14 July 2026; doi:10.1038/s41560-026-02119-1

European charging infrastructure targets rely on uniform benchmarks that overlook flexibility from smart charging (V1G) and V2G. A system model shows that V1G delivers most cost and infrastructure savings, whereas V2G provides smaller savings but substantial balancing revenues, particularly in photovoltaic-dominated, grid-constrained systems.Nature Energy, Published online: 14 July 2026; doi:10.1038/s41560-026-02093-8
Vacuum-processed perovskite solar cells show promise, yet their efficiency remains limited. Xu et al. use formamidinium acetate to promote perovskite crystallization, achieving a 25.5% power conversion efficiency and 1,000 h operational stability.Nature Energy, Published online: 13 July 2026; doi:10.1038/s41560-026-02096-5
Zinc-based batteries could offer long-duration energy storage, yet conventional zinc electrodes degrade during cycling. Now, a flowing zinc slurry battery is developed with zinc nanoparticles dispersed in a conductive network and a ligand that stabilizes the slurry. The slurry shows reversible Zn/Zn2+ conversion and enables durable battery operation.Nature Energy, Published online: 13 July 2026; doi:10.1038/s41560-026-02111-9
Elemental diffusion in Cu2ZnSnS4 induces secondary phases and defects, limiting the open-circuit voltage in associated solar cells. Wang et al. introduce two-stage copper incorporation to suppress copper out-diffusion, enabling 12.4% efficiency and an 874-mV open-circuit voltage in solar cells.Nature Energy, Published online: 10 July 2026; doi:10.1038/s41560-026-02102-w
EU import tariffs on battery electric vehicles may not substantially hinder the overall electrification process but may substantially reduce adoption in vulnerable markets. These findings highlight the uneven implications of broad trade interventions and underscore the importance of complementary policies to support a resilient and inclusive transition.
