The rising energy density and widespread use of lithium-ion batteries (LIBs) pose a growing safety challenge, marked by the potential for fires and explosions. Given the unique combustion characteristics of LIBs, the need for efficient and prompt fire suppression is paramount. Here we explore the mechanisms and characteristics of LIBs fires, emphasizing the critical design principles for effective fire-extinguishing agents and evaluating various agents, including gaseous, dry powders, water-based, aerosol-based, and composite-based fire-extinguishing agents, elucidating their mechanisms and effectiveness in suppressing LIBs fires. Noteworthy agents such as C6F12O and water-based solutions are highlighted for their superior extinguishing and cooling capabilities. Water-based fire-extinguishing agents show promise, exhibiting superior cooling capacity and anti-flash properties. Despite certain limitations, the review underscores the necessity of identifying an ideal fire-extinguishing agent that is thermally conductive, electrically insulating, cost-effective, non-toxic, residue-free, and capable of absorbing toxic gases. We conclude by discussing perspectives and outlooks, emphasizing the synergy between the ideal agent and innovative extinguishing strategies to ensure the high safety standards of current and future LIB-based technologies.

Syngas is an important chemical energy source with broad application prospects. The main problem with using syngas is its hazards, such as high storage pressure, high dispersion, low mass density, explosive, and toxic. The aim of this article is to find the key factors for the diffusion of syngas leakage and analyze the distribution of the dangerous concentration range from the diffusion behavior and hazard range characteristics of syngas leakage under complex working conditions. Therefore, a syngas leakage experimental bench is established, and a three‐dimensional simulation of syngas leakage was modeled. The results show that the initial pressure is the most critical factor, and the concentration distribution under different initial pressures is significantly different. The time required for carbon monoxide (CO) and hydrogen (H2) to reach their maximum concentration increased as the initial pressure or temperature decreased. The volume ratio had little effect on the time when CO and H2 reached the maximum concentration. In the horizontal direction, CO diffused further than H2 in the buoyant jet. The max volume fraction of H2 and CO did not exceed 1% and 2.5%, respectively. The research results are expected to give guidelines for the safety protection and standard improvement of syngas leakage.

Aqueous battery systems are increasingly recognized for their potential as environmentally friendly next‐generation energy storage solutions. However, their commercialization faces challenges due to the need for electrolytes that can operate stably at high voltages and in low‐temperatures. Traditional approaches to address these issues often involve materials that compromise the green nature. This review highlights the importance of developing environmentally friendly materials to improve the performance of aqueous electrolytes under high voltage in different types of aqueous electrolytes such as water‐in‐salt, molecular crowding electrolytes, eutectic electrolytes and cosolvents. In addition, we review advances in different types of aqueous electrolytes focused on using sustainable materials to achieve stable electrolytes at low‐temperature by suppressing water crystallization and lowering the freezing point. By integrating these innovations, we envision a future where aqueous batteries offer both high performance and eco‐friendliness, contributing significantly to the development of sustainable energy systems.
