Lithium ion battery with inbuilt fire extenguisher

Now a days one of the biggest issue that we are facing with respect to our mobile phones is its battery explosion.

Although the energy densities of batteries continue to increase, safety problem (explosion And fires) associated with the use of highly flammable liquid organic electrolytes remain a big issue, significantly hindering further practical application of the next generation of high energy batteries.

The encapsulation of a flame retardant inside a protective polymer shell has prevented direct dissolution of the retardant agent into the electrolytes, which would have negative effect on battery performance.

During thermal runaway of the lithium-ion battery, the protective polymer shell would melt, triggered by the increased temperature, and the flame retardant would be released, thus effectively suppressing the combustion of the highly flammable electrolytes.
