Scientists have come up with a way to prevent damaged lithium-ion batteries from catching fire. The battery effectively hardens upon impact, preventing electrode contact and causing a fire. Lithium-ion batteries are now dominant in consumer electronics due to their superior performance compared to other batteries. They are the most popular choices for portable devices (including cell phones and laptops), and they have a place in heavier applications such as electric vehicles. However, the damaged lithium-ion battery has the risk of fire. In addition to causing personal injury, it is well known that lithium-ion fires cause house fires and even aircraft crashes, such as the UPS Boeing 747 crash in 2010. Scientists said that in a lithium-ion battery, a thin piece of plastic separates the two electrodes. If the battery is damaged and the plastic layer fails, the electrodes may contact and cause the battery's liquid electrolyte to catch fire. Through the use of additives and traditional electrolytes, the research team at Oak Ridge National Laboratory effectively proposed an impact-resistant electrolyte. Upon impact, the modified electrolyte solidifies to prevent electrode contact. When used in batteries, the possibility of fire caused by damage is greatly reduced. The specific approach is to subtly avoid this situation by simply injecting a silica additive into the battery before adding the electrolyte and sealing the battery. Silica helps the battery harden when impacted. The additives used here are perfectly spherical, 200 nm wide silica particles, suspended in a common liquid electrolyte, forming a colloid. The research was supported by the US Department of Energy's Advanced Research Projects Agency-Energy and Oak Ridge National Laboratory. It will be exhibited at the 256th American Chemical Society National Conference and Expo this week in Boston, Massachusetts.
