It was shown on the basis of charge current, terminal voltage, and change in battery temperature that during thermal runaway, the observed changes cannot be explained by the self-acceleration of known reactions (due to overheating), battery charging and electrolyte decomposition. The observed changes can only be explained if we assume, that the thermal runaway is associated with a powerful electrochemical reaction going within the battery with a terminal voltage approximately 0.55 V. It is shown that the recombination reaction of atomic hydrogen accumulated in the electrodes is exothermic thermal runaway reaction in alkaline batteries. New mechanism of thermal runaway in Ni-Cd batteries, which explains all the experimental data known currently is proposed.

“…The organic electrolyte currently in use has several safety issues including flammability and electrochemical instability. The rechargeable Liion battery fails rapidly at temperatures in excess of 60 • C and thermal runaway occurs above 80 • C [1,2]. A potential battery fire in any consumer electronics or in an electric vehicle is a serious concern.…”

“…[3][4][5] A large number of theoretical and experimental studies have shown that thermal runaway is the main cause of LIB safety accidents. [6][7][8] On the basis of the studies of thermal runaway, scholars put a lot of efforts in order to increase the thermal stability of the LIB materials, [9][10][11][12] reduce the internal flammability, [13][14][15][16] and improve the battery thermal management. [17][18][19][20][21] LIB fire and explosion risk researches are also gradually developed, such as Perrine Ribiere et al explored the combustion behaviors of LIB using Tewarson calorimeter, and the results showed that state of charge (SOC) had a significant effect on LIB fire and poisonous gas generation.…”

Experimental investigation on the effect of ambient pressure on thermal runaway and fire behaviors of lithium‐ion batteries

et al. 2019

Summary To investigate the impacts of ambient pressure on thermal runaway and fire behaviors of lithium‐ion battery (LIB), experimental measurement and theoretical analysis with serial conditions are conducted at two altitudes. The well‐designed experimental equipment and operating conditions have enabled the accurate evaluation of ambient pressure effects. Results show that the first abrupt temperature change in Hefei (ambient pressure 100.8 kPa) is higher than that in Lhasa (64.3 kPa). The difference in ambient pressure at two altitudes leads to different relief valve crack temperature and time. The average burning rate in Hefei is larger than that in Lhasa, and the estimated pressure effect factor is quite different for detailed pack conditions and varies within the range of 0.083‐1.39. The ambient pressure has a greater effect on the heat release rate and total heat release than the mass loss, and the effective combustion heat under the low pressure is lower than that in normal condition. This work can provide more comprehensive and useful data for the safety management of LIBs at low pressure environments.
