Will Electric Vehicles Explode?

[MacJustin]

Electric vehicles can explode. The following are the scenarios where explosions may occur: Collision-induced explosion: While driving, if a collision accident occurs, the electric vehicle is highly likely to explode due to battery runaway. Whether the battery is ternary lithium or lithium iron phosphate, electric vehicle batteries store electrical energy through the gain and loss of electrons by lithium ions. As the most reactive element known, lithium ions will react with oxygen upon contact with air, leading to combustion and explosion. Charging-induced explosion: The main cause of explosions during charging is battery overcharging, meaning the battery is charged beyond its capacity. Overcharging leads to excessive lithium metal deposition at the positive electrode, continuously embedding into the negative electrode, increasing the battery's internal resistance and causing temperature rise. The rise in temperature then triggers micro-short circuits inside the battery, further escalating the temperature, making an explosion more likely.
