Dangers of Today's Lithium-Ion Batteries
Dendrites
|
Imperfections on the surface of the anode can cause buildups of lithium ions, also known as dendrites. Dendrites grow as additional lithium ions accumulate over time, resulting in a decrease of lithium ions available in the charging and discharging cycle. This decrease in lithium ions renders the battery less efficient. When the buildup becomes large enough, dendrites can puncture the separator and touch the cathode, short circuiting the battery and causing thermal runaway. Thermal runaway produces an excess of heat in the battery and causes an explosion.
Battery Explosions
Lithium is a highly reactive element that explodes upon contact with oxygen, which has led to many product recalls.
