Experimental study on the burning behaviors of 21700 lithium-ion batteries with high specific energy after different immersion duration

Progress of layered double hydroxide-based materials for supercapacitors

“…229 The interfacial regions of heterogeneous structures can provide opportunities to enrich the number of active sites 230 and promote electron transfer. 231,232 And strong electronic interactions in the heterogeneous interfaces facilitate the enhancement of electronic and ionic conductivity 233 and redox reaction kinetics. 234 However, the tightness of the heterogeneous interface is difficult to control, and the existence of voids between the interfaces affects the electrochemical properties.…”

“…Therefore, in the search for clean, efficient and renewable energy sources, 13 the development of energy conversion and storage must also keep in pace. The need to provide high-capacity and portable power supplies [14][15][16] for various technological products and equipment has attracted widespread attention, and for the above reasons, supercapacitors have emerged as the times require. 17 So far, supercapacitors have been developed for more than forty years since their birth, but the history of development in China is only about twenty years.…”

Harmful effects of lithium-ion battery thermal runaway: scale-up tests from cell to second-life modules

“…Finally, given that TR cannot be ruled out completely, tertiary explosion protection measures must be considered. As input parameters, information about the release of gases 22,23 and heat (the thermal impact on the environment) [19][20][21]45,46 is required. Experimental data for the heat release rate (HRR) and the total heat release (THR) have been reported in the recent literature.…”

Coaxial Electrospun Tai Chi-Inspired Lithium-Ion Battery Separator with High Performance and Fireproofing Capacity

“…With the increasing demand for high-performance electronic devices and the global mission to reduce greenhouse gases produced by fossil fuels, the development of rechargeable energy storage systems has received great attention, especially lithium-ion batteries (LIBs). − Battery separator is the core component of a battery, which can physically isolate the positive and negative electrodes, allowing ions in the electrolyte to pass through, which is closely related to battery safety. − Currently, LIBs pursue higher energy density to achieve small volume and light weight at the same charge. However, this also brings great danger: when thermal runaway occurs, the LIBs will instantly release enormous heat, leading to combustion and even explosion. , Therefore, developing high-performance and flame-retardant separators is the key to improving battery safety and efficiency. − …”
