“…defined internal short circuit). The results can then be used to create accurate models of battery cells or cell assemblies (Wang et al, 2022;Finegan et al, 2019). In this regard, high-speed synchrotron X-ray radiography is recognized as a highly valuable tool for studying the rapid internal events during TR reactions, and is being used by research groups to better understand the characteristics (Finegan et al, 2015(Finegan et al, , 2017aPham et al, 2020).…”

The investigation of lithium-ion battery failures is a major challenge for personnel and equipment due to the associated hazards (thermal reaction, toxic gases and explosions). To perform such experiments safely, a battery abuse-test chamber has been developed and installed at the microtomography beamline ID19 of the European Synchrotron Radiation Facility (ESRF). The chamber provides the capability to robustly perform in situ abuse tests through the heat-resistant and gas-tight design for flexible battery geometries and configurations, including single-cell and multi-cell assemblies. High-speed X-ray imaging can be complemented by supplementary equipment, including additional probes (voltage, pressure and temperature) and thermal imaging. Together with the test chamber, a synchronization graphical user interface was developed, which allows an initial interpretation by time-synchronous visualization of the acquired data. Enabled by this setup, new meaningful insights can be gained into the internal processes of a thermal runaway of current and future energy-storage devices such as lithium-ion cells.

“…10 DCP uses the external intervention (external short-circuiting) way to release the residual chemical energy in spent LIBs, which is manifested as an open circuit voltage (OCV) reduction below 2 V. 14,15 This is to avoid internal short-circuiting between electrodes in the subsequent dissociation process, inducing the battery thermal runaway effect and combustion. 16 Furthermore, the thermal runaway effect or combustion can change the state of electrode materials, which may reduce the value of electrode material regeneration products. Hence, except for directly smelting at high temperature 17 and freezing crushing, 18 DCP is the first step of processes in most cases because the stacking, transportation, and dissociation of the electrode materials in the disposal process will greatly increase the probability of the short-circuiting inside the cells.…”

The recovery of spent lithium-ion batteries is a key link of sustainability. The destruction of the chemical potential of batteries is an important prerequisite for a safe dissociation process and high-value recovery products. NaCl aqueous solution soaking is commonly employed for destroying chemical potential, and the release of pollutants is generally ignored. In this study, NaCl and Na2SO4 aqueous solutions are employed as media for the process of destroying the chemical potential, and the released pollutants are investigated. The galvanic and redox reaction paths are clarified according to the detection of the Cl2 emission, the pH value in the medium, and the phase composition of sediments. For destroying the chemical potential of 1 t of spent LIBs, about 0.52 kg of organic electrolyte solvent is leaked out to the medium; about 4.76 kg of lepodocrocite and magnetite sediment is generated in the Na2SO4 aqueous solution; and 5.49 kg of Al(OH)3 and Fe+3O(OH)-goethite sediment accompanied by 24 L of hazardous Cl2 is generated in the NaCl aqueous solution, causing an about 1 km2 zone seriously polluted by Cl2. A semiquantitative method is used to evaluate the comprehensive effect of commonly used media, and Na2SO4 and FeSO4 are found to be green media. This study aims to provide the pollution information and green suggestions about destroying the chemical potential of spent lithium-ion batteries during their recovery.

“…These include the perspective of designing efficient bifunctional electrodes for a novel generation of metal-air secondary batteries, , in particular with Zn anodes and aqueous electrolytes, either of the traditional alkaline type or innovative neutral ones, , as well as recently proposed solid-state ionic conductors . These devices are highly prospective for tomorrow’s green energy scenarios and enable the bypass of many issues associated with state-of-the-art Li-ion based technologies, chiefly the following: volumetric energy density, sustainability, environmental friendliness, recyclability, safety, and durability . Vast literature is already available, carefully investigating, dissecting, and reviewing the ORR mechanism in different environments and phases, and on several catalytic materials (metals, oxides, metallorganic synthetic materials, heme proteins, enzymes....).…”

Single Metal Atom Catalysts and ORR: H-Bonding, Solvation, and the Elusive Hydroperoxyl Intermediate

et al. 2022

The widely investigated oxygen reduction reaction (ORR) is well-known to proceed via two competing routes, involving two or four electrons, and yielding different reaction products, respectively. Both pathways are believed to share a common, elusive intermediate, namely, the hydroperoxyl radical. By exploiting a cobalt single-atom biomimetic model catalyst, based on a self-assembled monolayer of Co-porphyrins grown on an almost free-standing graphene sheet, we identify, in situ at room temperature in O2+H2O atmosphere, a hydroperoxyl-water cluster that is stabilized at the Co single-metal atom catalytic site. We show that the interplay between charge transfer, dipole and H-bonding, and water solvation behavior actually determines the hydroperoxyl-water complex stability, the Co-OOH bonding geometry, and, prospectively, opens to the engineered control of the selectivity of ORR pathways.
