Current commercial lithium-ion batteries typically use carbonate as an electrolyte. Carbonates are often volatile and prone to burning. During the thermal runaway process in liquid-state batteries, high temperature drives the vaporization of the electrolyte. The carbonate solvents may spray out and burn outside the battery.
Cracking open lithium ion batteries is a super bad idea. "...play with blobs of mercury metal and melt & pour lead in big open cauldrons (to make gamma ray shields for nuclear applications)" just the kind of experiments that led to this.
Small specks of lithium can embed themselves on your skin and cause tiny third-degree burns. Lithium dust in your airways can cause havok as well, although the amount needed to really get into trouble is very unlikely to come out of a battery. Only a few types of lithium (ion) batteries contain lithium metal.
However, note that all lithium batteries can experience a puncture under the right circumstances; there is no “puncture-proof” battery. Cylindrical cells are the most puncture-resistant cell types. What Should You Do If Your Lithium Battery Gets Punctured?
In addition to lithium-induced battery failure, the cycle life is another problem. For instance, the use of lithium as an anode causes dendrite growth and pulverization during cycling, thereby significantly reducing the life of the cell. The large volume change in a cell with a lithium anode is also an unsolved problem.
Lithium-ion batteries inevitably suffer minor damage or defects caused by external mechanical abusive loading, e.g., penetration, deformation, and scratch without triggering a hard/major short circuit. The replacement of cells becomes a dilemma if the safety risk of the defective batteries remains unknown.
