Preventing thermal runaway in lithium-ion batteries is crucial to ensure their safe operation. In this study, we report application of a poly[Ni(CH3Osalen)] polymer layer at the current collector to protect active materials in high-performance energy storage devices based on NMC532 cathodes. Poly[Ni(CH3Osalen)] has a conductivity window matching well the operational voltage of NMC materials, and it transitions to a nonconducting state when the potential exceeds safe limits upon overcharge, overdischarge, or short circuit. According to the stress tests performed in coin prototypes and ex situ XPS, EDX, and XRD studies, the polymer layer effectively limits current flow under extreme conditions and prevents degradation of internal components of the cell. While securing operational safety of the cell, the polymer layer allows for retention of up to ca. 90% of the capacity value of unprotected samples at an extended operational voltage range of 2.8–5.0 V. According to electrochemical impedance spectroscopy, the protective action of poly[Ni(CH3Osalen)] stems from the 10-fold increase in the charge transfer resistance at the polymer layer/cathode material interface, which compensates the sharp voltage change.

“…Heat transfer between cells can also propagate thermal runaway, expanding the scope of LIB fire accidents. 11,16,17 LIBs in thermal runaway produce a mixture of gases, including H 2 , CO, CO 2 , and various toxic substances, posing a severe threat to human safety and the environment. [18][19][20] Efforts to enhance LIB safety have led to the development of various thermal management methods and intrinsically safe designs.…”

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.

Battery safety is a multidisciplinary field that involves addressing challenges at the individual component level, cell level, as well as the system level. These concerns are magnified when addressing large, high-energy battery systems for grid-scale, electric vehicle, and aviation applications. This article seeks to introduce common concepts in battery safety as well as common technical concerns in the safety of large rechargeable systems. Lithium-ion batteries represent the most significant technology in high-energy rechargeable batteries and a technology with well-known safety concerns. Because of this, particular attention is paid to introduce common concepts and concerns specific to these batteries. An introduction of system-level battery issues that may cause problems in larger systems is given. Finally, a brief summary of the gaps in emergent technologies is provided. As most of the effort in new technologies goes toward improving performance, there are significant gaps in understanding safety performance of these new batteries.
