Unlocking Low‐Melting‐Point and High‐Conductivity Molten Salts via High‐Entropy Strategy with Demonstration in Thermal Batteries

open access: yesAdvanced Science, EarlyView.
A high‐entropy strategy is developed to break the trade‐off between low melting point and high ionic conductivity in molten salt electrolytes. By incorporating CsBr and LiF into the LiCl‐LiBr‐KBr system, the quinary LiF‐LiCl‐LiBr‐KBr‐CsBr electrolyte achieves a record‐low melting point of 229.5°C while maintaining a high conductivity of 1.19 S cm−1 at ...

Low Latency Global Carbon Budget Reveals Late 2024 Carbon Losses and Contrasting Early 2025 Land Sink Recovery Signals

open access: yesAdvanced Science, EarlyView.
Low latency carbon budget estimates for July 2024–June 2025 combine atmospheric CO2 growth rates, fossil emissions, ocean uptake, DGVM land fluxes, and OCO‐2 inversions. The budget shows that late‐2024 land carbon losses dominate the annual anomaly, while early‐2025 recovery differs between bottom‐up models and top‐down inversions, especially in ...
