BU-304a: Safety Concerns with Li-ion. Safety of lithium-based batteries has attracted much media and legal attention. Any energy storage device carries a risk, as demonstrated in the 1800s when steam engines exploded and people got hurt. Carrying highly flammable gasoline in cars was a hot topic in the early 1900s.
The mass loss rate of the battery is also greatly affected by the battery SOC and the electrode thickness, however, electrode material have almost no effect on the mass loss rate of the battery. According to the SEM images of the electrodes, it is found that short circuits cause graphite particles to break, separators to close and electrolytes oxidize on

When an electric vehicle catches fire, the underlying mechanism of the failure is complex, as shown in Figure 1.As thermal runaway continues inside the cell, 8, 9 the heat propagation will trigger the failure of additional batteries and the combustion of leaked gas will release additional heat. 10 It is evident that the vehicle or battery pack is
Accordingly, the discharge capacity decreases to around 1000 mAh g −1 at the 18th cycle. The complete failure of the Li‒S pouch cell happens at the 19th cycle in which the discharge voltage drops to the cut-off voltage of 1.70 V rapidly to render a sudden drop of the energy density to less than 100 Wh kg −1.
