This device effectively controls temperature through photothermally driven heat release under conditions as low as −40 °C and achieves a high energy density of 380.76 J/g even at −63.92 °C. The thermal effect is primarily due to light-induced molecular isomerization, a nonradiative relaxation process.
Conclusions Several large-scale lithium-ion energy storage battery fire incidents have involved explosions. The large explosion incidents, in which battery system enclosures are damaged, are due to the deflagration of accumulated flammable gases generated during cell thermal runaways within one or more modules.
One delayed explosion battery ESS incident is particularly noteworthy because the severe firefighter injuries and unusual circumstances in this incident were widely reported (Renewable Energy World, 2019).
Deflagration pressure and gas burning velocity in one important incident. High-voltage arc induced explosion pressures. Utility-scale lithium-ion energy storage batteries are being installed at an accelerating rate in many parts of the world. Some of these batteries have experienced troubling fires and explosions.
For instance, Atinafu et al. developed a graphene derived from solid sodium acetate to enhance the photothermal conversion efficiency, thermal conductivity, and energy storage capacity of PCMs. The reduction in supercooling increased the composite material’s energy storage capacity by 157.6 kJ/kg, which is 101.4% higher than expected.
