Fire Resistant Lithium-Ion Batteries
The scientists at John Hopkins Applied Physics Laboratory, US, have developed Lithium-Ion batteries that can operate under extreme conditions like submersion, ballistic impact, cutting and heat. In simple lay man terms, they can operate even under fire!
The Lithium-Ion batteries that are commonly used in every household item starting from smartphones are susceptible to catastrophic fire and explosion. Because of this, many phones were banned from airlines and ships. The US Navy had prohibited the use of e-cigarettes on ships and submarines because of the danger the batteries possessed.
The Technology behind the battery
The scientists have used water-in-salt and water-in-bisalt electrolytes in the batteries. These electrolytes were incorporated in a polymer matrix to reduce water activity and elevate energy capabilities of the battery. This gives the batteries higher energies to withstand heat and pressure.
